Greetings,

I've a 22' D&M sailboat. It weighs in at 4000 lbs with 2000 lbs of
ballast. Right now, I have a Johnson 15hp motor with a 20inch shaft on
the transom. The boat floats pretty much on its lines.

I'm experiencing a lot of cavitation when underway in moderate seas (2-4
ft) and am wondering if this is standard for an outboard powered
sailboat or if perhaps I need a longer engine shaft. Also, would
moving the tilt pin forward or backward help?

Any thoughts or comments would be greatly appreciated.

Thanks,
Nelson
