    Rpm vs pitch

    Got a 90 merc 2 stroke on a 25 ft tritoon. 13.25x17 solas 3 blade prop. I know the 17 is probably too much, only seeing around 4800 rpm at wot. How much rpm gain can i expect dropping a couple pitch sizes, maybe a 15 or 13?

    You'd have to do trial and error. Probably an 11 or 13 pitch prop would be needed. 90 hp on a tritoon is a pretty weak power package, as most have 115's at a minimum.
