Hey this is a great site!! Glad I found it. I'm sure if I look hard enough my questions have been answered. I have a 1993 MONTUAK 17 that now has a dead 1995 Evinrude. I keep the boat in the water 90-percent of the time, and when it rains I have to switch the bilge on. I want to re-power with 90-HP four-stroke Yamaha or Suzuki or the new E-TEC. Some of the sales reps I'm speaking with say I may have a weight problem, and it could be a problem because I leave the boat in the water. I would like some advice on re-powering and what can be done to set the bildge to auto on with out killing the battery after a long night of rain.

Thanks in advance for your help!

Hey Mitch! Mitch Ryder - hey you guys it's Mitch Ryder! Mitch, this must be you man!! Where are the DEEEEtroit Wheels, Mitch?
fee fee fi fi fo fo fum . . .

Advice you are getting is on target - best for you to dig into the reference section and use search feature. Lots of info, you will find many threads on this subject and probably a weight comparison chart. It is rich and deep w/ info. Hardcore Whaler geeks of every interest and discipline will post includng skippers that take boats like yours off shore.

Everyone will want to know what happened to your 95 Ev?

My 1985 Montauk with 90hp etec sits at rest with the transom drain holes right about at the water line. My console and seat have been shifted fore and aft over the years, I have a 13 gallon tempo fuel tank under the seat (the old Pate finally died), and the battery is in the rear of the boat; there are usually two decent sized anchors and line stored ahead of the console. I think I remember shifting the console forward after switching to the 90 from my old 70hp (I had moved it back to get more forward space). The motor mounting brackets are in the water, but the lower unit tilts way out.

I have no clue as to why a motor would make a difference on the bilge pump; my pump works the same with the new motor as it ever did with the old one! I can take on water above the height of the battery in a real deluge without problems, just have to gingerly step on the seat to reach the switch.

Heavier engine will have nothing to do with bilge pump unless you drop twim 200's on it which would cause it to partially sink at rest.

I think the zuki 90 is too heavy but a few here run them and disagree. I LOVE the 70 suzuki and think it i sthe ultimate montauk engine as long as you can live with 39mph WOT and burn 2+gph at 25mph cruise....awesome combo and much cheaper. The 90 will fetch you 41-42mph and costs about $1500 more...just food for thought.

Here is the recommendation from the factory on how to handle the problem of rain water collecting in the boat:

I have a 2004 Montauk 17' with a 90 Mercury 4 stroke and it is a huge engine, but it doesn't bog down, like I was told it might, on fast take offs. The performance of that boat with that engine is superb to me.
SeaSeaRider posted 09-19-2006 10:07 PM ET (US)     Profile for SeaSeaRider  Send Email to SeaSeaRider     
Thanks everyone for the advice. I'm still on the fence about which motor to buy. I leaning towards a Yamaha 90 4 stroke. The Suz 70 would be a the 2nd choice but is only 10 lbs lighter. There is only one service center here and It's on a side of town I never get to, were Yamaha has several options for service all with in 3 miles were I keep the boats.

It's the same for the etec 90. Only one place to service it about 18 miles away but still easier than Suz. I've been looking at boating mags and have notice no adds for the etech. Will Evinrude be around with this engine or will it phase out to 4 stroke tech? I could be convience to get Etech but need more info..anyone?

Thanks again for everyone reply - Hugh help.

You might as well check out the new Honda 90 EFI too.

I am in the same boat with same situation. I'm leaning towards the f90. Have you made your chioce yet?
SeaSeaRider posted 09-28-2006 09:53 PM ET (US)     Profile for SeaSeaRider  Send Email to SeaSeaRider     
No I have not made a decision yet. I leaning towards a Yamaha 90 2 stroke because of the weight. I've been speaking with a local boat dealer who I trust and he has put 90 F on serveral 17 montauks. Some of the owners love it but the ones who leave their boat in the water wish they had less weight on the back.

I may also buy a new boat - but hate to get rid of my whaler.

I will let you know what I do...I should be making a purchase in two weeks.

Thanks. I will also be making the purchase in the next two weeks good luck. The new Montauk 190 looks pretty nice. I'll keep you informed

I had a 1984 striper with a 2001 df70 suzuki and just loved it.What i did was install a stingray hydrofoil and put a sand bag under the anchor.After that it handled great,would jump up on plan fast and did'nt slap in the front unless i jumped it off a good size swell.I took this boat off shore 40 miles and ran all day could'nt run out of gas.Had 2 13 gallon tanks oh and by the way i never needed to take in for service as it ran perfect everytime all the time.Great engine would buy again.seems Yamaha is the most popular but that does'nt mean there the best,as a matter of fact check the boards and you'll find lots of different problems with the yamahas.Ask any Suzuki 4 stroke owner and he'll tell you the same thing i bet.Granted i never skied with it but for fishing it was great.i miss that boat as now i have an 18ft outrage but with older power that just slurps down the fuel,even just trolling.Good luck with whatever you decide.

Went with the 4 stroke yamaha 90 I'll let you know how it works out. My mechanic said that there should be no weight issues just that it might go too fast. Good luck

I love comparing 90's to the 70 so please tell us about your performance.

FYI dealer by me has new 70 2 stroke yammies for $4600+ and 90's for 5100+.

I maybe trading the whaler in for a new bay boat. How is your 90f-stroke working out?
borofsky posted 10-13-2006 02:55 PM ET (US)     Profile for borofsky  Send Email to borofsky     
i haven't tried it yet i'm in curacao but i figured it would have a higher resale value, it could be easily transfered to another boat if needed and i would be able to pull just about anyone up skiing. i let you know

Where I live a 90 is considered about the minimum that you would put on a 17' classic hull. There are many 115 Yamies (2 and 4 cycles), 130 Hondas or 140 Suzukis on the back of 17" hulls up here. But these boats are used like trucks. Most of the people on here (these forums) would shudder, or directly faint, to see what is done to our Whalers. One of the hottest tickets for a 17' is the 140 Suzuki; lighter than the 90 Suzuki and you would never lack for power. Extra power in the hands of the prudent man is not a problem and can come in handy.

I currently run a 17 with a 90 Etec and love it. It is a great compromise between the 4 and 2 cycles. Emission standards are better than many 4-strokes and at ~320lbs it does not squat the boat at all and is lighter than most 70hp 4-strokes. Fuel efficiency is adequate averaging ~3-5 mpg.

If I could repower a newer hull I would opt for either the 115 Etec or the 140 Suzuki. You lose ~30lbs with the 115 but at the cost of 25hp.

I live in the wettest place in the US, excluding Hawaii, so this makes me somewhat of an expert on bilge pumps. Our boat is in the water ~200 contiguous days a year and rainfall frequently averages 1" a day (we have had 5"+ in the last 48 hours). The only time I have had battery drain problems was prolonged periods of not running the boat, periods grater than 10 days. Our current battery is over 4 years old. The Rule automatic pumps are the best I have found.

**Note** The screen filter on the pump should be cleaned weekly or at least monthly. More frequently if small debris is common in your boat. And the filter must be used or the pump will likely fail.

That is my dollas worth of nickle knowledge. Take it or leave it.

Sea-BRP is spending very little on ETEC ads yet look how many people are talking about them. They are selling them as fast as they make them! I have one and love it! I am not worried about thier future.
jimh posted 10-16-2006 08:07 AM ET (US)     Profile for jimh  Send Email to jimh     
BRP recently reported that their outboard sales have doubled in the past year. Mercury reported their outboard sales declined. Mercury motors are principally sold as part of a mandatory tie-in sale with new boats built by boat builders that are also owned by Brunswick. These are captive sales and do not represent a particular market-based choice by outboard motor buyers. Evinrude E-TEC motors are being chosen by independent boat builders for new boats and many individual buyers for re-power applications on older boats.

Don't worry about a sudden shift in Evinrude engine manufacturing to four-stroke models. BRP will be sticking with the E-TEC two-stroke outboard motor until the conversion of the Jews.

Word around Wisconsin is that Evinrude's market share is up from 1% to 2%, as additional horsepowers above 40HP have finally come on the market. This bodes well for the future of the brand. We know Evinrude does not outsell Mercury and Yamaha, with no small HP oferings at all, but do they outsell the popular 4-strokes of Honda, Suzuki or even Tohatsu? Not likely.

Optimax has largest DFI market share, particularly in higher HP go fast, racing, and bass markets, but sales of 4-strokes are still gaining in overall market share as their popularity continues, and as promoted by Mercury, Yamaha, Honda, Suzuki and Tohatsu. Loose repowers are around 15% of total sales, and six companies are now competing for that small market segment. Included in this are loose small 4 stroke engines below 40, and for kickers. Divide that out and get the 2% figure, assuming all six get equal share, which they don't. Merc and Yamaha are big in loose sales too.

Looks like Larry is in to magic math again. Nothing to back up any of his figures! You would think his retirement income is based on how well Merc does! Gotta wish him luck! Those ducks in the Sister Bay Marina depend on it!

I can see it now...1980 with large rose colored lenses in aviator type frames. Rayon shirt with a big necklace and chest hair showing. Skin tight Sasson jeans and a BIG Burt Reynold's type stache and Larry saying....

OH PLEASE! Do you REALLY think those Jap cars are going to take over the US industry? GM and Ford have 80% of the market share, no WAY are they going to make a dent here. The Big 4 will always be on top, no WAY could GM ever go bankrupt. You can have your crummy little Honda, my AMC Matador is the best thing since sliced bread and I will own them forever.

Keep yapping Larry...keep yapping.

I would not buy a 4 stroke, 1st they cost more and I do not think you get your dollars worth, they are heavier, use the extra cash on fuel and other items, everyone I talk to about 4 strokes say they are not as fast and the fuel savings is not worth it. I would put a larger motor than a 90. you do not have to use all the power all the time but its there. Big engine pushes the boat easier (you turn a bigger prop hense more distance more power), Im in south fla, were a rain storm squall can come up in a minute, It sure is nice to have the power to make shelter.I have a 16'7'' 1975 hull whaler that I repowered and redid. The inside of the hull setup is a center console with a 27 gal tank and battery under it, I run a old 140hp evinrude looper (no vro just mix my oil no problems) that I bought new in 1985 when I redid the boat. I have not done anything with the boat since except for standard maintance and I love it, The large motor just pushes the boat with no effort and little fuel. Good luck

Not sure what 4 stroke owners you know or talk too but numbers do not lie. As far as cost goes, you now only have 2 choices...DFI or 4 stroke and they cost about the same. Actually 4 strokes are usually cheaper. As far as fuel on the 140 looper goes she will burn 7-8gph or so at cruise, a 140 suzuki does less than 5.

the 90 four stroke worked out fine. all the talk about too much weight doesn't seem to hold water at least with my particular hull. So far gps said 42mph. gas milage is way better then the 70 2 stroke. this is plenty of power for me with this boat. My mechanic says it's too much power he would have went with the 75 instead of the 90. nice and quiet. good luck

Judge my motor is a 1985 what year is the suzuki?? I would like to see that motor in 23 years. And I think your mpg are a little off.

2005 engine. Last weekend did 2.4 hours at cruise(4k) with minimal idle speeds at bridges etc. Filled her up after run and she took 8.42 gallons. I am not lying nor exagerating.
