You don't always need the power but it sure is nice to have when you do need it. Besides, the 15' is a hot rod anyway. ;-)) Cliff 1966 13' Sport with a 1993 40hp Yamaha 2 Smoker

I run a Johnson 50 hp (last of the 2-smokers), It work's out well for me. I follow the re-power rule of 75 to 80% of "Max. rated H.P.". This gives good fuel economy, good balance, and enough "Oats" to get out of the way of trouble quickly ! Matt

A 50 hp motor setup properly will do upper 30's , 60 hp low 40's, 70Hp mid 40's. The bigger the motor that better it will handle passenger laods or watersports. It will also cruise along at high speed and/or lower rpm. Dave
