Just purchased a 22p ss laser2 prop from a guy i met and got a smokin deal, I currently run a 19p ss prop. I no there is room for more prop on my boat. I just was wondering if anyone has had this setup or currently running it and also what is the top mph you reached with the prop. Im currently running 42mph at 5500rpm with my 19p ss.

Thanx Ryan.

3" pitch cahnge is going to bring wot rpms down to like 5000 which is on the low side,and hole shot will suffer. everything is worth a quick try though. come back with results.

well tried the prop on the weekend and it went well, Suffered a bit of rpm loss but it still worked well. IT just didn't scream like she use to with this prop on.:D:D Im gonna try a 21pitch and see if there is any change.

what were wot rpms with 22" laser? 4900? one more thing how is setup cavitation plate in relation to bottom of transom. seems like every motor could go up an inch to improve performance.
