Have a 2003 40 hp 2stroke on a 20 foot pontoon Stock OMC 3 blade 12 3/8 X 13 . At 15mph 5000 rpm it vents . Have to back off throttle .
Do you think a 4 blade will work better and stop the ventilation Or maybe a 3 blade stainless?
I have a omc 15 pitch but it keeps it below 4500 at full throttle
Thanks in advance
