It sounds weird, but would a 40-HP Honda on a 1984 Montauk 17 work? We could quit drinking beer and throw all that money into the "More Power" jar. John

Yes it will work but top end MIGHT be 30 on a good day. Many are happy with 50hp so a 40 would not be too far off. I have heard of a 30hp but I think that is pushing the envelope a bit.

Toshgib, based on your reply here and on the other recent thread involving the 22' OR with a single 150, you are very optimistic when it comes to performance #'s. My 1983 Montauk has a 1985 johnson 75 hp, and top speed is about 30 knots(34 mph). I consider the boat underpowered with that motor.(just to clarify, while I do enjoy going fast, that is not what I mean by underpowered, I like to be able to have a boat totally pigged out with people, fuel, and gear, and be able to get up on the step.) With four adults and 1 child plus 12 gallons of fuel and beach gear this summer on 4th of July it was all she could muster to get up, and it still took probably thirty five or forty seconds once I hit it.

I would be willing to bet that with an average load, the forty would have a lot of trouble planing the boat out.

Keep filling the jar.

Having just repowered my Montauk with a 60hp E-TEC , a 40 would only work for in certain situations . Propped to plane I don't think you would see more than 25MPH and if you propped to try for 30MPH , more than a light load would be extremely slow to plane.

Whaler says min hp for Montauks is 35 hp.

Some years back we repowered a smirkless 17 with a 50 , It was used in the junior sailing program and it worked fine, but we wanted it to be slow.

Yeah, I swap the 1998 Evinrude 70 hp 4 stroke off my 15 Sport with the Honda 40 hp on the Montauk and voila, I have two under powered boats. John

2many we also had/have a smirkless in our youth sailing program. The first power we had on it was a donated 40hp Nissan 2 stroke. I was adequate for pulling Opti's and I used it regularly as a mark boat. Never had a problem getting it on plane. It was OK with one or two aboard. We then installed a donated 50hp 4 stroke. Performed a little better. Last summer we re-powered it with a new Suzuki 50 4 stroke. I used it as mark boat one regatta and was very pleased with the performance. It won't be a speed demon but for light duty I think it would be OK.

Explain to me me how a boat the size and weight of a 15' Whaler can be considered underpowered with 40hp of any stroke. You may wish for more power and that's OK but I don't see it being underpowered. I learned how to waterski behind a 60's era 16' ArrowGlass with an Evinrude Lark. It was a tank, you could fit your 15' Whaler inside the ArrowGlass (sans motor).

sounds like you better get two jars

I think it depends on what kind of beer you are drinking. In the summer I have been known to get the $3 per six-pack no-name beer. It's cheap, and it's cold. And on a hot summer day that is about all you need. When the weather gets colder, I tend to switch to some micro-brewed Pale Ales, and they're about $9 for a six-pack. Once in a while we'll have a drink at a bar, and there it's $3.25 a beer, or about $20 a six-pack.

How fast you can save up for that new 40-HP Honda depends on what and where you're drinking.

Jimh, you need to shop around more for your beer. Hint: get
24 Oz cans. I can regularly find Coors/Bud 24s for $0.99,
which equals 2.97 a six-pack of 12s, but the 12s wil cost
$4.99 in the same store. Go figure. (All prices plus tax
and deposit).

Well the beer thing has not worked so far. The 70 on the Sport is fun. It would be hard to go down. Who has got a 40 on a Sport anyhow? I was content with our 35 Lark on the Skagit 15 also, untill I got a different boat. This is the prompt for the post.

Just move the 40 over to the kicker bracket and put a 90 in the center.

John,

You guys need to jump on that boat! No kidding, a Montauk in that condition on the West Coast is worth that all day. If you are worried about power, have the dealer swap out that Honda for a BF75 or BF90. He will probably even take the 13' on trade.

FYI, that 40 Honda would be great on your 15'. Not a rocket, but what a great combo for fishing and fun.

Heck, I might have just talked myself into a road trip to Oregon!

Now I just need to decide on what type of beer for the trip ;-)

Andy, you are absolutely correct. I need to make a couple of calls.

Poop.

Oh. by the way, everybody please disregard my link to the Montauk. It's probably all beat up and they photo-shopped the pictures. I am sure its been a salt water boat and all you "fresh only" people know what that means. Probably got lots of water in the hull also, that is why it sits so low in the water, well if it had a 90 on it I am sure it would only have a couple of inches of freeboard. The transom has got to be shot also, all that weight. It's a total loss. Forget about it. John

John,

Act quickly my friend...If I had more time off, I would have a new fishing boat.

Maybe up there it is a steal but I think $10k is steep for a 1998 engine.

Mobjack I was not saying it is not underpowered, I was saying it would work which is all he asked. My father's first fiberglass boat was a 1962 Nauset with a 40 Johnson and he loved it. Tops speed was about 28mph which was not bad back then.

PS if yu are running heavy loads then a 75 might not be enough for you. All I can say is my 70 4 stroke would do 39+mph and get 5 adults and a dog out of the hole nicely, moreso than my 90 Yamaha would.
JMARTIN posted 12-04-2007 12:21 PM ET (US)     Profile for JMARTIN  Send Email to JMARTIN     
Do you think the 40 would be too heavy for the 1987 13 Sport? John
Tohsgib posted 12-04-2007 12:47 PM ET (US)     Profile for Tohsgib  Send Email to Tohsgib     
Nope! Many have them on their hulls. My setup weighs close to 250lbs and although I would like less weight, it is not an issue and runs fine.

I hear you Tosh, and I am not at all certain that my engine is generating the power it did when it was new. it is relatively low time(450 hours) but is 24 years old. I plan on repowering as soon as financially able, and I am planning on getting either a two stroke yamaha 90,(mainly from the price and reliability standpoint) or an Etec 90.
Tohsgib posted 12-04-2007 02:40 PM ET (US)     Profile for Tohsgib  Send Email to Tohsgib     
The old 75's are more like 65hp today. I would not however recommend a 70 Yamaha if you want more performance, not enough cubes. The 90 is a good choice but 4 strokes are getting easier to find at good prices now that they have been around almost a decade.
Mobjack posted 12-04-2007 03:17 PM ET (US)     Profile for Mobjack  Send Email to Mobjack     
Yeah, I know, but I am a little worried about the additional weight and the loss of hole shot ability. This is a topic that has been discussed on this board relentlessly, and I plan to do my due diligence beforehand when I really get ready to do the repower.

Don't believe the hype on holeshot. Yes it is a tad slower with light load but with 5 people it is just as fast...weird.

I would be wary of a 40hp on the smirked Montauk. I rigged a 30hp tiller on a much lighter 1971 pre smirked hull this year and with just me could get 21-23 mph. Put two medium sized people onboard and the hull would barely plane but eventually did and got 16 mph. This was a gutted hull with no rps ,or console much lighter than a newer smirked hull with interior componentry. Yes, I was using an older tired two stroke motor and the Honda propped right might be OK with light loads. I would just be a bit wary. When using modest power on these hulls setup is even more crucial and they are very load sensitive. Even with my less is more approach I found myself looking for a nice 40 or 50 hp tiller motor.

Just finished reading the 1974 brochure and they show a 16' with a 40 Merc towing a skier. They claim 26mph and 30 with a 50hp. They also had a 19 Outrage with twin 40's and claim 31mph.

Don't forget the 5 cent deposit on the cans. That ought to get you another 10 hp.
