I've removed the tounge from one of mine and it does real good on my Enforcer Sport & G230. Went a step further and cupped the tips a little. Didn't notice anything. My next step is to thin it out real good and try rolling the edges a little. Then I want to round out the tips and cup a little more.

Thing most people will tell you is do one mod at a time. Test under different conditions to see how each one reacts. Then, mod again.

Another thing I've learned from running high speed fullsize boats is don't ever turn down the chance to try another prop also.[8D]

Check out these links and see how some are done.

Chat later.
