I was on a friend's boat earlier this year and noticed it starts listing once the engine speed reaches 3000ish RPM or higher.

What would be some of the causes for this?

The boat is older Glastron 19' bowrider propelled by a Merc V6 and Alpha 1

No trim tabs
Whale tail on the outdrive
Prop pitch unknown at the time of this post
