what is the absolute biggest OB I could get away with :devil2: ?

25

depends. need to see pics. what is it rated?

no clue, trying to clean up the plate so i can read it
12' fiberglass gamefisher

I got a 15 on 14' aluminum and it moves along good. Fiberglass boat is heavier I am sure so maybe a 25 would be perfect to more than enough. Paul

Is it one of the rough-finished Gamefishers, the ones without any gel coat? If so, I wouldn't go more than 15hp on that boat. My buddy had one with a 9.9 and it moved well with 1 person.

I have a 13 whaler, my 25 Yamaha moves me at about 24, plenty of motor

thanks guys :cool:
