Hull vibration when coming on plane
I'm experiencing hull vibration and noise when coming on plane on my single engine 454 donzi. Once on plane it goes away. It feels like it's coming from the bottom of the hull and makes this "woo" "woo" cyclic shuddering sound and goes away if I throttle back or once I get on plane. Turning is no problem, no vibration at all. Just when under load when coming on plane.
My mechanic says my prob checks out ok and the u-joints/gimble bearings are new.
I come on plane with drives in and tabs down never exceeding more than 3000 rpm.
Any ideas? Is this prop cavitation?
