    Does anyone have recommendations on maximum horsepower for an '88 M-171?

    Rating tag says 135, I'm considering a new 150 4stroke to replace my old Johnson 120 looper. Boat will be used at high altitude- 4-7000'- mostly higher end. Looks like the 150 Tohatsu or Honda is 113# heavier than old 120

    most 17's were rated for 135 hp.

      Yes that's what the placard says.

      Wondering how this boat would handle 100+ pounds additional weight on stern. I don't think the power would be an issue at all, at my altitude.

        Short answer no, long answer would be to take 100lbs and put it on the transom, think sand bag or a kid, and look at the water line. If it looks okay and is still self bailing then go for it but odds are youd need to move some weight around
