Just looking to see if anyone has any quick advice for this... I get a vibration on my 390 Sundancer between about 2800-3300 RPM that smooths out after that and cruises beautifully. Bottom is clean. First V-drive boat, any help to leads to get this figured out is much appreciated. I would think if it was a drive-shaft or prop issue it would only get worse with higher RPMs.
