Nice calm day on the lake yesterday so I thought I may see what top end is on new motor. Playing with the trim I maxed out at just under 50 on speedo (forgot to bring gps) and 4800 rpm with 15x17 aluminum prop. Should I be happy there since I rarely run fast anyway or could I change prop pitch for more top end?

Only you can decide if you happy or not but just to make sure what's the operating RPM range of your motor.

Gator, A stainless prop will always out perform an aluminum prop. The aluminum props flex as speed increases and that changes the pitch. If I were you I would find a "OMC Raker" "19 or "21 pitch. they are a good all around prop. Good luck!

the rat.. :D
