I am repowering my 17 montauk wiith a Yamaha F90 four stroke. I am removing a 1983 evinrude 115 crossflow and I am concerned about the weight difference which I believe to be about 60 lbs. Any problems with that? Any thoughts would be helpful. Thanks in advance. Kevin

From what I can find it seems to be 301-320 lbs

For three years of model runs, 2000-2002, Boston Whaler shipped oout a couple of thousand white classic Montauks with the 386# Mercury 4-stroke 90. At the time they were saying the boat was rated for 410# engine weight.

I too will be looking to re-power my 17 Montauk, once I find it. =) I have always thought it would be with a Yamaha 90, but I'm also considering the below due to the weight issue.
Let me know how everything goes with your re-power, hopefully I won't be far behind you.
Yamaha 70 - 257lbs
E-Tec 90 - 320lbs
Suzuki 90 -341lbs
EDIT:
Corrected weight of E-Tec 90

I will move the battery to the console to shift some of the weight. I am in too deep to back up now! Any other suggestions will be wonderful. Kevin

Montauk 17' 1979.
In 2005 I replaced my 90 Johnson 2 stroke with a 90 Yamaha 4 stroke. I put the battery in the console.
Yes it sits a little lower in the back, you cannot reverse the engine really hard unless you want water in the stern, but other than that, the gas mileage, noise and running performance make up for it.
I would do it again as the yamaha is a great motor, always starts, runs great, sips fuel and no smoke.
The same gas tank capacity provides double the range.
No one ever told me, the boat sits really low in the back, it is hardly noticeable.

Wrangler, Thanks for the post. I felt it may sit a little lower in the water but, my fishing and boating are in the gulf flats or inland lakes. Following seas will not be a big problem so forward I go with the repowering. Thanks all for the responses and thoughts. Kevin

It is not likely to be a big problem. I have a 2002 70 HP Suzuki (about 350). The fuel tank and batteries are moved forward. The splash well drains are only under water if you move behind the helm seat. Yep i am currently installing a bulge pump! I have just installed a 19 gal bait tank behind the helm seat. We will see what effect that will have.
