The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I have a 15 hp Merc Pro Kicker with a 14 spline 10x7 4 blade prop that is on a 16' pontoon. At full throttle the motor cavitates but at slower speed it is fine.
The pontoon mfr suggests switching to a 3 blade prop. The motor has an extended shaft.
What pitch should I get for a 3 blade prop...
