[QUOTE="scoobeb, post: 431575, member: 6843"] Also a perfectly tuned 25hp 2 stroke can spin a 13 to 15 pitch prop unlike a 25hp 4 stroke, not happening. With a 14 or 15 pitch prop your lucky to get on plane. My 25hp 2 stroke merc I sold easily spun a 15 pitch prop and the torque was there,I doubt a 25hp 4 stroke has the torque to spin a prop that big at least that I've seen. Most spin 12 pitch props and that is pushing it,lol. [/QUOTE]
