Ready for Summer

Second time out with Imco"s and -2 shorties. I don't love the cavitation when getting on plane, can live with it though. Picked up 3 MPH and 300 to 400 RPM with less trim with a full tank. Still tweaking and adjusting but results are not bad.
Prop slip is 17.7 so thinking maybe a 5 blade should help slippage and cavitation planing.

I have found give it a bunch of throttle as soon as the nose starts to drop you can back off. If you leave it while cavitating it will continue. I probably run up to 3600 it's cavitating so really not hard on drive, and back down when it comes over, then you can get back into it. After that they rock. I also found getting on plane while turning it keeps the hull away from the front of the prop. Where I can I use that method, I also though of 5 blades but concerned for the stress on drives.

guy that built my drives calls five blades drive breakers.
thats what i found out, soon as they slip i give it more throttle and back off as the nose drops.
