If the engine is running well and has been properly looked after, why bother changing it. I would recommend a compression test on the cylinders to check that they are all performing well and maybe think of carrying a smaller outboard as a back up and make sure that you have a decent radio and know how to use it properly.
How is maritime safety around Hong Kong since the Royal Navy pulled out?
The boat will be better balanced if you leave both consoles in and you will have plenty of room for electronics plus the below decks locker is huge so maybe best to keep it. Does your locker have a bilge pump fitted or just a plug to keep the water out. Mine has just the plug but the system works well.

thanks your advance. the trader give me the same suggestion as you ... keep the still running eng. and one small eng as back up. because trade in the existing one only value for usd300 to usd400.. by the way,
it just a plug to keep water out.
this Sat. i will drive the boat from HK east to Hk west ..it is a long distance may take around 2 to 2.5hr for it. the wind is East 3 to 4 .. it would be little rough on the sea.
i will renew all the seats with new cushion. it may cost around usd250-300, i think it is good investment return with good looking and comfortable.
by the way, are you still keep your SL16? or, already changed a bigger one?

It is a good idea if there is nothing wrong with the engine to leave it on there, just make sure that it is in good condition and use it.
These boats are tough and scrub up well, if you spend some money it should look good for a long time to come. We will keep ours for as long as we can, we don't need anything bigger.
If I remember correctly there are a lot of bays and sandy beaches where you could shelter if the weather gets bad, the throttle is your best friend if the waves get big just travel more slowly and the boat will get you there.
I was 5 months in Hong Kong on HMS Yarnton in 1985 with the Royal Navy and had a great time.

I have also been in Honk Kong several times between 1990 and 2000 and also had a great time. During the start-up of a large radiation monitoring system for the ROHK, we were flown by helicopter, on a daily basis, to and from remote islands where these monitors were stationed. These were often British marine pilots. Sometimes, if the weather conditions were bad, we needed to be brought to our destination by boat...talk about rough seas at times. From the helicopter the view of the mountains, green sea and the many islands was absolutely fantastic. You could also see sharks swimming around in the shallow water at times. A great experience indeed.
We also spent many hours having beers, in an Australian bar called the Kangaroo Pub, with American marines. This pub was actually a supporters location for a local rugby team I think. It was great and filled with very friendly people although I sure wouldn't have wanted to get into a serious difference of opinion with some of these guys...or women for that matter. They were huge, man ....
Oh, and I also think the SL16 is a fine Whaler. It is often underestimated and discarded by some Whaler enthousiasts. I think this model was the foundation for the post-classic Legends as they were introduced.

Good luck,

Erik

Dears,
the reason for me to buy the sl16, price issue is nr.2.
nr.1 is that i need a boat i could handle it easy by my own. of course, sometime, i will go out with other fishmen.
the reason for such small boat is i really like the harbour. here had many small island around us.
everytime when i landing home (HK).. look down from the air, the green sea, dark blue sea, blue sea... and the small green island ...
i always think with myself: am i really live here? so many place i never been ...
i already had a 28ft chris craft for 10persons, but this not a fishing boat not a easy go one...
but, someone is so lucky (just like the tv show believe or not) .. in fact, i never see the shark but dolphins.
wish every one had a nice /fun week end. bye

I love it when someone asks about the 16SL. And I love the old 2000 postings by LHG where he trashes the boat and then admits he has never been in one.

I can't help Kai with information regarding how the boat handles in open sea. Dave Weight and his brother are the experts on that subject. But we have enjoyed our 16SL since 1992 and taken it everywhere. The latest was to northern Wisconsin near Hayward. For us that is 300 miles. I got 19mpg on our 2002 Toyota Sienna. We boated on two different lakes this time. The boat is easy to trailer, launch and load even when the launch ramp is primitive. So we are happy BW owners because the boat when have chosen fits our style of boating.

When I looked at my owners packet I found magazine articles I had collected at the time we bought the boat. Jim Barron, writing about the boat said, "it is a giant leap toward conventionalism. I'm not sure I like it, though." He adds, "That is not to say I'm down on Whaler." He had a Nauset that he loved. He adds, "In spite of the design changes, the 16SL is an excellent performing hull. The riding and handling qualities are similar to previous Whalers, but the new hull is drier in rough, windy weather. The hull planes easily and corners with only a modest amount of banking."

Joe Raguso in Motorboat magazine wrote a glowing article about the boat and gave the 16SL Motorboat Magazine's "Editor's Pick" award. Raguso writes, " Based on a fresh 15'6"L by 6'6"W hull, it is not reconstituted platform by any means." Later he says, "There is something on the Whaler 16SL to please every member of the family." He then enumerates features to pleas both the fishing crowd or the skiing fanatics. He notes the tremendous amount of storage space for a boat its size. Motorboat tested the 16SL on Sarasota Bay. Raguso adds, " This is also an efficient platform, planning 2800rpm with the Yamaha 90 and 19 inch stainless steel prop. Waterskiers will appreciate its out-of-the-hole performance;time to plane takes just under 3.6 seconds. Top speed was over 43 mph." Raguso finishes, "There isn't much that I'd recommend changing on the combination platform. Other than some of the performance nuances I mentioned earlier, the Whaler 16Sl's hull and layout are about as right as they can be for a boat this size. The Whaler design team did a fine job of designing this 16, and C. Raymond Hunt & Assoc. did an equally fine job on the running bottom. So if you are looking for a utilitarian sportboat that is not not only a jack of all trades, but a master of most of them, check out the 16SL."

Finally from Dave Mull of Lakeland Boating magazine. Mull likes the boat, which he tested near Saugatauk, Michigan. He mentions all the storage, comfortable ride and being dry. Mull ends his article with this line, "Whalers are an established sea going classic, and the 16SL is a fine addition to the line."

So if it is this good what led to its demise? In my opinion it was price. The invoice on our boat in 1992; this is boat, motor, trailer, cover, battery etc. was $21,283. That is premium for a 16 boat, particularly in 1992!

So here we are 16 years later with a boat load of great memories from boating on the Hudson River, Puget Sound, Coeur d'lene, four of the Great Lakes and the Mississippi ,plus numerous Wisconsin & Michigan lakes. Isn't this what boating is all about? So I submit that the 16SL is not a Whaler loser, but a sound boat that offers great fun.

I just heard from someone on this blog who bought a '92 boat, motor, and trailer for $7000. What a deal. I have seen others for sale for $9000.

One other issue. I would not put on a motor bigger than 90hp, nor would would I add a 4 stroke. In my opinion the 4 stroke is too heavy for the hull.

I am anxious to hear of Kai's decision. I hope he goes it.

Dear RFK. Dave..Erik,
thank you for all of your information.
in HK whaler is not common .. for the price issue. a new whaler is expensive.
honest speaking, whaler looks is so so .... but between my boatmates .. whaler is a good boat... checking on internet,still many peoples talking on this topic. sounds
that i make the right decission on it.
specially thanks Dave comments help a lot.
next week , i will try to take my OLD SL16 back to my home place ... it drive from East to west... i will cross the victoria habour, the most busy and rough sea of hongkong, .. to test the performance of such OLD , small boat and Eng.
i keep the old eng. as Dave suggestion as well as RFK too.
last night, i cannot sleep well for i dream with my new toy SL16... i wish n hope SL16 will bring me a lot of fun and exciting...
highly expected in SL16.
keep testing report update later.

Will be interested in hearing about your trip across Victoria Harbor. That will be an interesting accomplishment.

Because of the pressure to own a "real" Whaler, I have looked at the possibility of moving up to a Montauk or a Ventura. Both are nice, but they don't offer sufficient gain to make the move. In each case it would mean not just up-grading the boat but also consider a bigger tow vehicle. In our view it wasn't worth it.

If you haven't seen a 16 up close I will tell you you would be amazed at the storage. One console will hold 6 life jackets. Underseat storage will hold towels, extra clothes etc. The anchor locker will hold two anchors and plenty of line. The 6 ft. in floor storage will hold skis, line etc., or beach equipment; folding chairs, umbrella etc. There are still two in-floor lockers in the rear which I use for tie downs. Sometimes the rear lockers are used as coolers. So when you are underway everything is out of the way and tidy. And I haven't mentioned the lockable glove box and storage under a rear seat.

So I no longer yearn for a classic and am satisfied with this throw-back Whaler version which is unsinkable and in its own way delightful.

Dick

I know Victoria Harbour very well, you need many sets of eyes to get through there safely but at least you have enough speed to get out of the way of things. Your boat should keep you dry from spray just remember to slow down for the wakes from the Star Ferry etc.

Your boat will do well, just remember it is 15 feet but it is a Boston Whaler and the ride is very good for such a small boat, we fish at sea in the English Channel which has confused sea coming from all directions at the same time and very sharp waves as well, just change speed for the most comfortable ride and you should be fine.

At the risk of boring people, I thought I would add another anecdotal note on 16SL boating.

Yesterday we took friends to Madison,Wi. to boat on lakes Mendota and Monona. We put in on the east side of Mendota with a plan to show these folks UW-Madison from the water. The university is on the south end of the lake. There was a 15-20 mph breeze coming the southwest to northeast creating a 11/2-2 ft. chop. I told the ladies if it got too rough we would go to plan B. I found that between 1500 & 2000 rpm I could get enough bow lift and speed to make it a comfortable, dry ride. I got periodic spray in the helm seat, but not enough to get my clothes wet. Good design and higher free board helps. If I had tried the same trip with our 15 Super Sport Limited we all would have been wet just getting out into the lake.

Lake Mendota is connected to Lake Monona via the Yahara River. You lock through, then follow a channel from one lake to another. (There is now a $5 charge for a round trip through the lock.) The one downside to the afternoon was seeing the lack of water clarity in the Yahara. When we first visited Madison years ago it was crystal clear and there were no weeds.

Lake Monona was much more calm than Mendota so travel was easy. I wanted our friends to see Monona Terrace from the water. Monona Terrace is the last public building to be built from an old Frank Lloyd Wright plan. It is a gorgeous building and a great addition to downtown Madison. It is particularly beautiful to see lighted at night as it shines out over the lake.

It was another great afternoon of boating. Incidentally, another asset of this boat which makes these trips easy is its 24 gal. built-in gas tank. No plastic tanks sloshing around in the stern of the boat. Just check the gauge and go.

I'll quit now.

Hi Dick
Still all present and correct, I can't post photo's, I have tried but for a decent view of our boat go to www.greenwichyachtclub.co.uk select photos from the left hand column and then you need to find a folder marked 2007(135) then London Regatta page 2 and there we are acting as photo and news crew boat for this prestigious Fall event here on the Thames.
Tom W Clark
If you read this, congratulations to yourself and your new wife. You are welcome back to Greenwich Yacht Club any time you are in the vicinity, Chris and I would love to buy the two of you a beer.
They close the Thames Flood Barrier for the day and almost completely stop the tidal flow on the Thames for the whole days racing, no mean feat.

Dave,

Found it. Good picture and the information on the club is interesting. I love the club house. Looks like a fantastic place to have a pint. I can appreciate why you like being part of membership.

For those who feel a "smirk" on the bow is an essential part of the Whaler brand, I hope you take note that 16SLs do have one. In fact, I would argue, more pronounced and classic than some of the new Dauntlesses.

For what its worth, I just posted this in the GAm area:

I have a 16 SL, and despite the derisive comments here (i.e. on the GAM area thread), I am prepared to say I think its a great boat. But what do I know - its my first boat. However, unlike most of you (from the GAM thread), I have been out in one!

I fish the coast from San Diego, around the La Jolla Kelp beds mostly, but have been on a few longer trips - one to the Coronados and back (66 sm round trip) and a few trips out to the 9 mile bank which from where I launch is 11 nm pretty much due west out into the pacific.

Its only a small boat, so heading out into the swells with livebait on board can restrict speed to around 11 kt or it gets airborne too much. Its only a modified V. On flat water with the original Yamaha 90 it will go more than 40 mph but I am never in flat water - typical cruising speed when not carrying bait or going due west is around 19 to 21 kt.

I put a pair of trim tabs on it which helps a lot at the higher cruising speeds in moderate chop.

The best thing about this boat - well there are two: 1) the amount of storage. It has a generous anchor locker up front. Each console can hold a lot of stuff for example i have 4 pfds, a throwable, fire extinguisher and my flares in the port console. I store boat documents, tools and then jackets and a fishing belt in the stbd helm console and there's room for more.

Food, snacks, drinking water for two people (I fish with two people most of the time) go into the seats forward of the consoles.

The "Ski Locker" presumably is long enough for skis, but it makes a great fish locker - more than twice the capacity of the lockers on say a 21 ft Outrage. And its fully insulated so it holds ice all night & all day and keeps fish very fresh.

To the rear are two small insulated fish boxes where I keep frozen chum or other fresh bait and other odds and ends.

I have two batteries under the rear seats so all that stuff is out the way.

The other great feature of the boat is that it is very dry - the bow flare works very effectively and we get essentially no water in the boat at any speed.

MPG is around 3.2 nmpg.

Its small enough to keep in the garage, its easily launched and operated by 1 person, and for my purposes it is pretty much perfect.

Limitations? A larger boat would have a) faster travel capability uphill and b) more range due to a bigger gas tank.

The boat handles the ocean well but I have not been out in it in rough weather - it handles wind chop very well, small white caps are fine, but I have not been out in anything really rough. It handles the swells coming over the bar just fine going in and getting out and I have had no issues in a following sea, given the preceding caveats.

i just back!
start boating at 14:30, finished at 16:30. spend around usd150 for the trip.
mostly the speed at 4500rpm. sometime down to 3000rpm. (i guess it should be less or around 20knots)
reason is busy travel and rough open sea of victoria habour.
both of you are correct,SL16 easy to handle and it is a dry boat!
but, my eng. is too much noise! this is not only point i am upset for but not the boat.
for sure, in the coming future i will boating with BW more and more ..

A 16SL fan club. That is something fun to think about.

Dave, would it be okay to have the Greenwich Yacht Club (GYC) as our home port? That would add a little class and international flavor to the club. Next we need a place for the annual meeting. How about GYC? The club house looks like a perfect setting for this venture.(If you can afford a 16SL what is a ticket to London?) Here it gets a bit touchy, would having the meeting on the 4th of July be seen as too tacky, Dave?

My first motion would be to nominate lhg for Honorary Commodore of the Fleet; my second would be to offer a toast to him for motivating us to get organized.

For the meal, could Dave and btb provide fish? I would be happy to bring Wisconsin cheese and corn fed beef tenderloins. ( My fishing skills are under developed and that adage "teach someone to fish and they will never go hungry" has never worked for me. I buy fish at the store.) Leigh, another owner in Louisiana, might be talked into bringing oysters and some Cajun specialties. Kai might be willing to bring Chinese noodles. I am sure there are other potential members who have special contributions to make to this feast.

I don't know where we should start on membership fees. How about $100? Then there is the question of owners of other models, should they be given an opportunity to join as associates? I do think center console boats should pay double, since their boats only perform one task, fishing. Ours are multi-purpose and can handle recreational boating and fishing.

It is an interesting idea to think about. Gee, it the communication get fast and furious, maybe jimh would create another category just for 16SL owners.

Just a note, I am writing this in the morning and I haven't had anything to drink.

I am sure GYC would be glad to host such a club, Chris and I could provide deep fried Skate wings (Thornback Ray), with chips (English for French Fries) Subscription would have to be £50 Sterling and the 4th of July would be a great idea, we could have a cup of tea at the end of the day.
We think we may have the only SL16 in the UK and I would guess Kai's is the only one in Hong Kong. They are few and far between.

Thank you, Dave, we have a start. Incidentally,the GYC logo certainly offers opportunities for adaptation to our cause.

I have made a request of BW to see if they will give us the actual numbers of 16SLs produced.

We have not had Skate so Nancy and I would look forward to giving that a try.

I did receive a response from C. Bennet at BW on my question regarding the number of 16SLs built between '91-'94. The number manufactured is not being given. However, I was told that the "SL" refers to Ski Locker. That is something I had never heard before.

Skate is a throw back to the prehistoric, but a very "meaty" fish.
From memory I think there were less than 350 made, I can't remember the source for that memory.
Ski locker sounds feasible, it's almost big enough for me to sleep in at 270 pounds overweight. Unfortunately our foot throttle sits squarely on one edge of the lid and so ours gets relatively little use unless we forget to put the bung in and fill it with 1000 pounds of water.

Dears,
i am prapare the map to told my store of victoria habour in details.
i am freshman of the BW.
does any one could told me that 90HP 2 stoke at 4500rpm should be equal to knot? (please concern the eng may be at least 7yr old!)
Sept 14/15/16 .. i am little busy on BW SL16.. after clear up the boat, it looks much better and good looking.
it is easy to control , my boatmates like it too ... it is simple for control.. some of my guests are ladies... they can handle it easily too.
but i had small problem with the eng... it is not easy to switch ON! also, not easy to put it down too. may be some INT for the wires.
what's the best pick up speed for BW SL16?
the head is goes up, then comes down ...
i try 5500rmp... it still stable ...
but, my problem is i did not feel the speed!

i also interested in the same question as you: the actual numbers of 16SLs produced!
if you had the figure, please post it on site.
in my yatch culb (gold coast yacht and country club), we had 4 BW boats.SL16 is the one and only one in our yacht club. i am not sure how many pc will be in HK, but i don't think it is common.

any suggestion:
if install a new 4 stroke eng. on SL16.. does 70HP is enough? 90HP would be too heavey ?

erik selis posted 09-16-2008 04:00 AM ET (US)     Profile for erik selis  Send Email to erik selis     
Kai,

I'm not sure but are you running a Mercury, ELPTO 90-hp, 2-stroke engine? If so I also know they are difficult to start. Here's how to best start the engine when it's cold:

-Make sure you have pumped your primer ball until it is hard. Holding it in a vertical position while pumping is best.
-Push the release button on the side of your control lever and put the lever in a 45° angle forward. I don't know what type of control unit you have but I assume there is a release button on it. If you start and the engine is running too fast, bring the lever back a bit. Do not exceed 2000 RPM.
-Turn your ignition key into the starting position and start the engine while pushing the key. This will prime the engine a bit more. When the engine is running stop pushing the key. If you feel that the engine will stall push the key again but very briefly. Repeat this until the engine runs on it's own.
-Let it run for a shortly while the control lever is in the 45° position but make sure you don't exceed 2000 RPM.
-Bring the lever back into the fixed-neutral position and let it run. The engine should not stall now unless it needs some adjusting.
If you have the engine manual the starting procedure should also be described in it.

To stop your porpoising problem, maybe you could put some weight forward and trim the engine inwards. I have heard that you can also solve this problem by screwing/gluing 2 small stainless steel plates to the transom of the boat. The plate has a small 30° bend and it extends about 1/2-inch below the hull bottom. It wasn't a 16 SL but a 17-ft Alert that had porpoising problems due to too much weight at the stern. It seems these small plates drastically improved the boat's ride. It took some experimenting though.

Erik,
the used eng. is : Evinrude , 2 stroke, 90HP, v4
just difficulty to turn it ON. once it was ON, everything works well.
doing the same as , pumped the primer ball before start ..
i need to turn the key many times to start the eng. does it is normal? But, when it runs on ... it is easy to restart again.
in my experience with "Chris Craft" (in-out-board) .. just turn the key on .. an go, that's it.
could i fix up this problem by re-wire it....etc.
or, it is normal for such aged 2 stroke eng?

4500rpm around ? knot?

BTB and Dave
i will goes out by myself too .. so, what will be and must be watching out during boating?

Did you tell us what kind of 90hp motor you have? 7 years old certainly doesn't make it ancient! I re-powered in 2000 replacing a Johnson 90 with a 90 Yamaha 2 stroke and I couldn't be happier. The motor has been trouble free!

Your questions are now going to lead us to ask about the size of your prop and are you saying your trim feature on your motor is not working?

4 stroke over 2 stroke; my 90hp 2 stroke Yamaha weighs about 265 lbs. (Sorry, I am not good at metric.) A similar 4 stroke is about 100 lbs heavier. I judged that to be too heavy for the boat. Personally I think having a motor in the 250 - 275 lbs range is ideal for that hull. At the time I would have had to go to about 50hp 4 stroke to stay in my ideal weight range. You now may have more options. Suzuki might have a four stroke at a good weight. Since your boating is in the ocean I think the weight issue may be more important for you than someone like me who boats almost exclusively on inland waters.

Your issue of high bow when you start to come too plane. Like Erik asks, do you have the motor all the way down or as close to the transom as possible? Then tilt out after coming up on plane.

How much speed do you want? The more speed you want will mean a higher pitch prop, which in turn will effect how fast the boat will come up on plane, particularly if you have five or six people on the boat. I boat mostly with my wife who has no interest in going 43 mph in our boat. Plus we bring couples with us who also are not interested in speed, but cruising. All the occupants tend to be smaller than Dave Weight, but still of good proportion, plus a few beers and pop. Therefore I use a lower pitch prop that gives me plenty of "out of the hole" power and I can have the boat on plane in no time. Top end speed for the prop I use most of the time is in the upper 30s. I can plane the boat quite easily with six adults on board. But I have them sitting toward the front of the boat. (These small collapsible chairs fit perfectly in the center isle of the boat.)

Porpoising is easily controlled with the trim. I had much more porpoising with the Johnson motor and prop than I have with the Yamaha and my current prop. With my current combination it is almost non-existent.


Good to hear that as you clean up the boat it gets better and better looking. I also think yours is probably the only 16SL in HK harbor. (I remember being in Cozumel diving and we came into the harbor and low and behold there was a mammoth yacht that had a 16SL on davits on the upper deck. I wasn't sure I liked seeing my boat as someone's tender. But I did credit them with having good taste.)

We are really impressed with the quality of Stainless Steel used on our boat and the build quality is really impressive.
If you contact Tom W Clark here at Continuouswave he sells a set of CD's which cover nearly all of the Boston Whaler boats including the SL16.

Kai, your hull number is stenciled on the transom. Ours appears to be hull #201 and built in '91.

I put on our alternative aluminum prop which is 131/4 x 17. It is a little bit faster at the top end, but won't blow your hat off. I tracked it on our GPS, but our river is full with so much rain so the current is running at about 4mph and makes getting definite speeds a bit difficult.

Dick,
my last boating form Hongkong East to Hong Kong South.
i just measure it on the map. it is total 55M. i used 2 hours for it. means 27.7mph around 15Knots/hr in average. of course i did not count the wind and water flow.
this week end i will fix up some cable problem of the Eng, lighting, horn ... may be you will not believe .. all cables were disconnected in my boat .. no red/green light, white light and even the horn was lost too!
once fix up, i will try to speeding up to see what's the mix speed would be ....

27.7 MPH should be 24.4 Knots or nautical miles per hour.
Did you measure the distance of 55 miles on a nautical map or use GPS or similar.
We use a stainless steel Laser II prop and have maxed out at 43 knots or 48.9 MPH in a slight chop with 2 lightweight people on board

Dave,
measure the distance of 55 miles on a nautical map
1.8M = 1 knot? right or wrong?
if it is 24knot speed ... i did not had such speeding feeling. or in the other words .. SL16 is very stable!
daveweight posted 09-18-2008 05:34 AM ET (US)     Profile for daveweight  Send Email to daveweight

1 mile on land is 1760 yards
1 nautical mile is 2000 yards approximately
1 knot equals 1 nautical mile per hour or 2000 yards per hour
So 1 nautical mile equals approximately 1.13 land miles
Or conversely 1 land mile equals 0.88 nautical miles
And yes Sl16's are very fast and smooth.

Boating on the open salt water, i put a weight on the head. so the wave comes , i could moving forward more stable. does it is correct way for it?

Are you saying that you are putting weight in the front of the boat to keep it down.
If you get the boat "on plane", and then use the tilt and trim to bring the front of the boat down to a good angle. We do not use any weight in the boat to change it's angle, start off with the leg of the engine tucked in close to the back of the boat and as you get on plane you can start to gently use the tilt and trim to move the leg of the engine away from the back of the boat to bring the front down. With practice you should be able to not have a weight to do this for you.

Dave and all Dears,
just check the ele. eng. and discovered that one of the ignition without spark, this is the reason for difficulty starting and once the eng was warm up, it works okay... the technician said that for such OLD eng. is not wealth for repair. just keep the eng running till to it's end.
some of our boatmate suggested change to 4 stroke eng.
but the technician comments is 2 stroke eng. for 2 stroke eng. would be more simple to handle and lighter than 4 stroke. also, cost less and suitable for small boat as SL16.... did you had any comments. (the existing eng. is 10years OLD)
i searching on internet E-tec sounds good .. but someone also say it is BAD for must keep on updating .. otherwise, the computer will lock-down the eng.! Does it is true?

My Mercury 90 2 stroke is 12 years old and still running well.
The SL16 is a fairly narrow boat designed for the weight of a lighter 2 stroke engine. Most 4 strokes will be heavy for it.
Can you buy old second hand parts on ebay and try to keep the engine good. If it is a bad spark is it a coil or a lead or a spark plug. Remember your boat has done a lot less hours than a car and so 10 years is not very long if maintenance has been OK.

Dave,
during the compression test , when we turn the key, one of the left hand side without enough pressure. one of the left hand side is nearly no pressure. means only half of the eng. (right hand side) is activate for starting, sparking. The technician said it will still work for several months or 100hours. then the right hand side will goes down, less and less power... i am not technical people, i know nothing about the eng.

An E-Tec, 90-hp would be the perfect engine for your boat. Lots of power and acceleration and very light weight.

Erik,

A Yamaha at 261# is a better fit, in my view. The 90hp E-Tec is a horse at around 350#!

Tom W Clark posted 09-20-2008 06:19 PM ET (US)     Profile for Tom W Clark  Send Email to Tom W Clark     
The Evinrude E-TEC 90 weighs 320 pounds, not 350 pounds. It is a vastly more sophisticated motor than the Yamaha 90. It is quieter, cleaner and more fuel efficient.

The Yamaha 90 in comparison is an excellent, old-school two stoke outboard much like the venerable old OMC 70s.

erik selis posted 09-20-2008 08:15 PM ET (US)     Profile for erik selis  Send Email to erik selis     
Dick, no doubt the Yamaha is a bullet-proof engine but I was thinking if Kai is going to buy new why not take advantage of the newer, cleaner, quieter and better fuel efficiency of the E-Tec (lighter than the 4-cycle engines).

Dave, I don't quite understand your last post. Are you advising Kai to mount a kicker engine in general or only if he would mount an E-Tec?

Erik

Dears,
i think the best way is $$$ .. e-tec and yamaha 4 stroke is nearly the same cost in hongkong around usd7200 .. if i buy the new 2 stroke traditional style... it cost usd5000.... the cost different equal to half year fuel cost! of cours if budget okay, buy the best one , most latest technic issue is the best choice.
RFK posted 09-21-2008 01:53 PM ET (US)     Profile for RFK  Send Email to RFK     
Gentlemen, I am sure E-Tec and four strokes are technically better. The 16SL has a rather narrow stern. The transom is approximately 6ft. wide at the top,while bottom of the transom is approximately 5'8". For me the issue becomes what 90hp engine provides the best buoyancy and handling characteristics for the boat? Kai operates the boat in big water, with lots of turbulence. Therefore engine weight, in my judgment, is important. I think Dave Weight concurred with me on this point.

After checking available 90hp engines, it appears to me the Yamaha offers the best power:weight ratio. The Mercury 2 stroke weighs in at 303#, that is 40# over the Yamaha. Admittedly the Yamaha is old technology but in some ways so is the boat. It is almost old enough to be a "classic'!

I was suggesting that he carried a kicker in case his current engine broke down on him, and possibly with any new engine he buys as well. His area of boating can be very remote and dangerous at times.

Dave, that's a very good suggestion indeed and I fully concur. The reason I don't go out in our coastal waters without a companion boat is because I haven't mounted a kicker motor yet. Like you said it makes no difference if the engine is new or old. Another reason why engine weight is so important on Kai's boat.

dears,
boating is for fun and safety is nr. one.Nothing could be fun without safety.
i will mount a kicker as backup. also, kicker also using for fishing! this is best way to hold in position against the wave during fishing.
But, the new eng. must be quiet than we could talk freely during boating ... the existing 2 stroke is too much noise. So what's the suggestion? E-tec would be good .. but someone say it create trobule always and lock down itself .. always need to software upload ..etc. does it is ture.
if i buy the traditional 2 stroke .. does it quiet?

last week end we are boating with some BW owner in our yatch club. SL16 works well! i love my new toy very much and for sure will be more and more in the future.

Kai,

If you wish to talk about re-powering your boat maybe you could post a new topic in the performance section. You will most likely get more response there. Not everyone reads the post-classic section, you see, and many have been re-powering their older Whalers for a long time.

I believe there are several options for you boat. IMO if you want a modern engine you will need to consider the weight of this new engine. I think Honda has a fairly light weight 90-HP out now. Also the new Suzuki's should weight much less than the previous models. I already mentioned the E-Tec option.

Erik


RFK posted 09-24-2008 08:28 AM ET (US)     Profile for RFK  Send Email to RFK     
Re-powering in this case means the main engine and a kicker, so the weight of both needs to be considered from the get-go.

Sounds like you want the safety of a kicker and quiet of a 4 stroke.

If you are mostly fishing/boating alone. You might consider a Yamaha 60 4 stroke and a small kicker 4-6 hp.

Tony and I were out this weekend in San Francisco Bay which may be similar in conditions to Hong Kong. His 15 foot Boston Whaler with 60 hp 4 stroke was more than enough power even against an ebbing tide.

i get the offical information from BW, the min. request is 55HP and max 90HP.. i think for boating, fishing 20 to 25knots is good enough for me. i must say thank you for all of you, specialy Dave, Erik and Warren ... wish both of us will enjoy our SL16, BW and wish every one with happy life. bye.

Hey Kai, since you are going to explore some of the islands near you, make sure you get a kicker motor as a backup too. Plus you wouldn't want to be dead on the water with freighters, barges and ferries coming at you.

My backup motor (kicker) has saved my son twice and I have a new outboard. The first time my son left my live well running for hours with the ignition off, which killed the starting battery. The second time was a fuel line at the Fuel Supply Module that failed. Both times, the kicker motor got him back to the ramp.

Good luck and post some pictures.

Warren

PS. I took the pictures of Tony. Also, I predict that you will get a larger Whaler within 12 months. :-)

here may be some interest information about our SL16. informatoin from BW.

IMO, SL 16 is over design in 1991-1994.
please take a new BW catalog to compare our existing 16SL with 18' Ventura.

email copy as below:

Hello Kai,

The 16'SL was originally replaced with the 17' Dauntless. The 17' Dauntless ran from 1996-1997. After that the 18' Ventura took its place.

The standard referral source for canvas is Mills on Long Island. They have all the Whaler specs. Otherwise I think you would have to find a custom shop where you live.

I would be interested in hearing what Mills could design for you.
