sand the running surface of the bottom.don't be shy. good for 1-3 mph on the adverage. give me the numbers so i can crunch them. rpm @ wot / prop pitch / gaer ratio. that will help me help you.

Randy,
Have you checked your Xdim. and do you have room to move it up or down?
Have you checked the bottom to make sure its straight?
Have you check to see where your CG is?
Do you know what your slip factor is at the prop?
What size prop are you running and at what RPMs,is it a 4 blade or a 5 blade?
Bravo prop or a Hydromotive?
We have done alot of testing with the sport master drive and it is not always fast,we have tested on some boats and run 2-3 MPH slower.We also found that they dont like to run at a high Xdim. and usally work best between 85-90 MPH.Thats why they work so well on F-2 boats and not on F-1s.
If we do the math we can tell if the problem is the boat or the prop and aleast know where to start...Good luck!
