Hi team
A friend recently purchased a new Yamaha four stroke F15 outboard along with a 3m rib for his teenaged sons. it would seem to be underpowered not quite getting up on to the plane when two up. Can anybody suggest a way of boosting the power output to that of the F20 which appears to share the same frame and capacity of the F15.
We have tried trim/ moving bodies fore and aft without much success.
Magic wand please chaps
Regards
