Howdy,


Sounds like a LOT of other stuff is going on.

First, I highly doubt that the engine is turning 6500. Get another tach to verify (or ensure the switch on the back of the tach matches your engine 4, 6,8 cyl)

A 13p prop might be right for a boat that big and an engine that small (115hp? I don't know anything about an AQ115)

What should your engine turn at Wide Open Throttle (WOT)?

Most sterndrive engines turn 5000RPM or less.
