View Full Version : Prop sizing

Does anyone have any prop advice for a CSX 220 with a Indmar 400 HP motor? The current prop seems small and can't tell the pitch. It is a 3 blade and RPM's seem high when cruising 20-25 MPH.

ahh... the classic find me a prop thread...

call eric at OJ. include what your activities on the water are, how much time is spent doing each, how much ballast do you normally run with, and tranny ratio (not sure what the CSXs are... i imagine 1.52:1)
