You'll notice a big gap where I just couldn't run at 2500 RPM. Just past 2K rpm it would bust up on plane and the motor would simultaneously rev up and haul out... I couldn't control its desire to get on plane.

Every motor does that. That because as soon as the boat gets on plane, it takes a lot less hp to maintain that planing action. It may take 60% power to get on plane, but then only 40% to stay on plane. So at 50% power it won't plane off, and at 60%, you've got half again as much power as you need to stay on plane.

The question is, can you extremely carefully throttle back to 2500 rpms without falling off plane?
