I put a new Honda 90 on my 1985 17' Montauk. It has swamped twice now i believe due to the motor being too haevy for the boat. Has anyone had this problem? Is there a place i should have looked for specs on what i could have or should not have put on the boat?
thanks

A 90 shouldn't be a problem on a 17' Montauk.......Sounds like you may have other issues such as water in hull or large gas tank in rear or someting else adding lots of weight to the rear. Can yu explain a little more detail in what you mean by swamped

Thanks. Well I had the standard 1984 Johnson V4 on it and a kicker (8 hp 4-stroke yamaha), rode just like it had for years. then we put the new motor on and with any sort of chop the boat gains water. Twice now it has taken so much that it would sink if it could of. I've had a couple of dealers since who said they wouldn't have sold me one, i now just want to get the right motor for the boat and I don't know where to find some specs to tell me what i can or cannot put on the back of the boat. gas and everything else is standard equipement, i can see no leaks with it in or out of the water. thanks again.

Here is a list of Current Engine Choices and the Weights.

I think discussing another motor is premature.
I have a friend who has a older Honda 90 (even heavier than the new model). His boat rides a bit low but not a problem.
If the battery is in the stern, move it forward and into the console.
Do you have a stern seat?
I think you should remove the kicker and run the boat for a while. You don't need it. If you need to troll slowly, consider a trolling plate for the main motor.

While I would rather see a lighter engine, the 65 or so pounds you have added should not cause this much of a problem. However, I assume the kicker is still installed, and now maybe in total, there is just to much weight. Was the boat's trim low in the stern to begin with?

Thanks for your replies. No the boat sat fine with the old motor and existing 4-stroke kicker. I definately need the kicker for fishing and getting out of the shallows when the tide is out. I should mention that the boat is on a bouy, and we have had whaler's on that bouy for decades. the battery is in the console and i have a standard seat behind the wheel. the only way I've found to fix this is to take one of the tanks from beneath the seat and move it up to where the cooler/seat is infront of the console. This is definately not a way to keep or have a boat, one more swamping and i can loose it all.
Is there a link for the specs for that boat? Our manuals we lost long ago. thanks

I have a 1985 mantauk with a 90 hp Honda that has been on it since 1996. No problems.

Two 4 strokes on the transom is apparently too heavy.
The Honda 90 is apparently at the limit of weight all by itself.

Joe - thanks for the earlier list, but what is the weight limit? Whaler must have published one?

The Montauk did not have a maximum weight for the engine, rather the horsepower (100 hp).
I often moor my boat on an out-haul off a stone pier. At dead low tide, there is only 1' of water. I use my extendable gaff to get me out a bit then tilt down to the top of the trim range and idle out.
I, for one, would be interested in seeing how your boat is sitting. Can you post some photos to a personal page?
FYI - The Honda site lists the new 90 as 365 lbs dry.

Any chance that the hull is wet? The foam could be full of water.

I thought of swapping the 4-stroke kicker for a 2. But aside from introducing new fuel issues, that apparently would only shed about 20lbs. of weight (depending on the model) which really would be a negligible difference.
