I am looking to repower my 16'-7" Whaler and I wanted to know opinions and feedback on the Yamaha F70, Suzuki DF70, E-TEC 75 or 90 and a 2004 90 HP 2 stroke. If anyone has these on a boat similiar to mine please respond. I will post pics of my boat another day, it has a different console, unsure if its original. Thanks.

Must be a Cohasset and there is no such thing as a 1972 Montauk.
The Montauk was first made in 1973...

Look at our Current Engine Choices in the Articles section.
Look at the weights of each motor....

Here are my first 2 choices whether you prefer a 90 or a 70...
E-Tec 90
Yamaha 70 4 stroke

Yeah, I know there is no 72' Montauk, but isn't the Cohasset just another version of the Montauk with the exception of a different console. Everything else seems identical.

No, the Cohasset came before the Montauk...

Then came the Montauk

We need to call the model what Boston Whaler called it when it was made. Otherwise why have names for the different models?

Thanks for the links on the different engines, whalercentral is great and I'm really stoked on fixing up my first whaler.

I have a 70hp 2002 yamaha 2 stroke on a 1970 smirkless hull.

The lowest planing speed I can come up with is roughly 19 mph (sog per GPS). I'm told that a more powerful engine would allow me to plane at lower speed, though I'm not sure how much lower that speed would be.

W/O a means to measure full flow I'm unable to adress fuel consumption with any degree of accuracy, however, I'm somewhat satisfied with its' rate of burn.

I also would like the engine to be a bit quieter.

While having a following wind at the same speed as the boat can be a bit annoying, oil consumption is remarkably low therefore there is very little smoke and the attendant fumes.

Looking in the rear view mirror and if I had the $$ I'd have held out for a fuel injected newer 70 hp or 90hp 4 stroke.

Hope this helps.
