Re: How fast?
It all depends: I know of one on a 15 foot deep vee Glastron V153. It goes 55 MPH. You have a bass boat; it is bigger and heavier yet built to go fast.
Still, how fast is fast? It all depends. Depends upon the condition of the engine, the way you have it propped etc., etc., etc.
All told though if you were to go less than 40 you should be disappointed. Top end ? you need to find someone with the same rig.
