    20" lowe Suncruiser

    just bough a 20' lowe suncruiser with a 90hp two stroke Yamaha. tach does not work, but gps speed is 18 mph with a 13.25x17 three blade prop. I think prop is too big. what are your thoughts? I think a 13.25x15 would be better - I know I have to get tach fixed too.

    Definitely try a 15" pitch. Might even have to go to a 13". Most 90 HP'ers on that size toon work well with the 15". You should be in the mid to upper 20's on speed..
