Hey-
I was wondering if anyone could lead me in the right direction in trying to pick the right pitch & diameter propeller to use for a #6 drive. Are there any calculation charts available? Thanks much!

There's a little more to it than that. HP vs Wt, Hull design etc..Your best bet is to contact one of the larger prop companies like Throttle up or Blades for info.

Or go to the forum of your brand boat and get your answer from the guys that know.

Here is one I use.

Thanks for the link.

Easy one for you guys. RPM x Pitch divide 1056 divide gear x % of slip. Use it all the time to see if guys are B/S ing.
