Cavitation
Subject: Cavitation
From: Nelson Kirsch 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. Your experiencing airation which is not uncommon in that type of boat. It sounds like you need a longer engine shaft. Or a way to lower the outboard you already have. Capt. Bill |
