Is a 115 Merc (98 Model) too much weight at 347 lbs and too much power for a Montauk? Thanks, TL

I'm currently replacing my Evinrude 115 with a Yamaha 90 and can tell you that you won't have TOO MUCH power, but probably more than you need. I don't know exactly what my top speed with the 115 was, but I do know that the boat started to get "squirrelly" at WOT. Power for pulling up skiers was awsome.
The weight should not be too much of a factor except for making your BW sit a little low in the stern.
I opted for the Yamaha because of it's light weight and hopefully greater fuel economy.
I'd say if you are getting a really good deal on the motor, go ahead. There are several in my area with the older, tall, in-line six 115's and owners seem satisfied.

Does anyone know what the effect would be on insurance for the boat if it is powered by more than the recommended max. HP? I have also considered a 115hp to replace my 88hp. Nearly the same weight and they look identical, but with more power. I do a lot of boating with up to 6 people and some skiing so I could use the extra power, but I was concerned with the max HP limit. Any thoughts?

I've got a 115 Suzuki on my Montauk and it works great. Check it out at http://www.danwagner.com/whaler/whaler.html

To MikeG:
I don't know if it is a universal principle for insurance companies, but I was turned down for boat insurance as well as a two million dollar "umbrella" policy because of the 115 on my Montauk being 15 over the rating. It is my understanding that even in an accident where you were not technically at fault, you might be assumed to have some "contributory negligence" by having your boat over-powered. I got by with it for 19 years---no problems---maybe I was just lucky!

My opinion is the way things are now with so many boats PWCs here there and everywhever, you have to anticipate that if something were to happen, even not your fault, it is not worth the gamble to have a boat "overpowered".

Your insurance co., after hearing about your choice of engine, will run for the hills.

The insurance company of the other party (in an incident) will eat you for lunch).

In my opinion, it is just not worth exceeding the USGC rating of your boat.

I had no trouble insuring my Montauk with a 115hp. As for the weight (370) - it's no problem. The new Mercury 4-strokes Whaler is putting on the new Montauks are even heavier. My mechanic wanted to put the carbs from a 140 Suzuki on my boat (which is the only difference between a 115 and a 140) and I told him he was crazy. In the meantime I'll get a magic marker and turn the 15 into 00 ; )

After being in the businesss of selling Whalers for a while, I can tell you that there may be liability issues for you if you if you ever sell a boat to someone and it has an engine over-rated for the boat. And if any insurance company has no problem insuring an overrated boat, I hope they have deep pockets, because they are at huge risk. The Montauk, in my opinion, has more than enough power with a 90; a 115 is over the top and could be very dangerous. I think it can take the weight, but the HP is too much.

I think a 115 would be fun on my montauk if I could afford to repower. Right now I can't. Is it too much? That's a matter of opinion. I would probably like it. I used to have a 15' Hydrostream rated for 120. This was a low profile speedboat that weighed about 500 lbs. I had a 200 V6 on it and some people thought I was crazy, But I enjoyed it. When the family was in it , I could cruise at 45-50 at a very low rpm and when I was alone or with a friend, I could blast along at 80 when conditions permitted it. It was fun, but I do enjoy my montauk with just a 60 on it more than any other boat I've owned. I guess priorities change with your age! The thing I would like about more power on it is on flat water, I feel like I'm crawling at anything but WOT, but I don't like to run that way for long periods. But in rough stuff the motor is perfectly suited to the boat. It is also very economical and with the 27 gal. tank, it seems like I get gas about every other month instead of every day like my old boats. Just my .02 hope I didn't ramble too much!

I agree with dscew. Also check with the Coast Guard. I believe you may be fined if you exceed the max hp for your Montauk. My 90 Yamaha is all the motor my Montack needs. Especially if you ever let your son drive!

I don't think the CG cares about max HP, but
some states do.
