Have you tried any other props on the boat. Say a 7013-3 rounded??

:? 7013, never heard of that one, sure your not talking 7016 ?

Tim, I tried a Dasbota 7016/3 rounded ears, on my Hurricane with a Full Mod Piranha and my Rampage with a Pro Mod CC.

On the Hurricane I liked the 2614/3 Ernie Special

On the Rampage I liked the 6717/3 425c from Brent

The 7016 seemed to be a little heavy in the turns compared to the ones listed above.

Here is my 90* Need For Speed 1" band steel pipe and 2716 prop on my Sprint, the motor was refreshed by Redline in June and I think Mike had put a turbo crank in it as he told me in the email..this thing was not slow, it went 73.5 mph.
