I just purchased a 2002 donzi zr competition. It is rigged w/ side by side twin 875hp w/ bravo xr s w/ 2 inch shorties. Does anybody know what pitch prop i should start. 5 blade or six blade. Thank You

Hi Chris. I have an 03 Comp with staggared motors. I know the boats like a 5 blade prop, not sure of the 6 blade or what pitch you will need. Also, I am running standard length Xr's on mine. I have the boat that was the Donzi in house boat from 03-07. They tried many different combos on it and found this was best. Again, staggared vs. side by side could be different.

What kind of HP do you have? What size props are you running now? Thank you

35p six blade.. dont know it that will even be big enough.

I have twin Ron Potter 700+ hp's. They are built up from from 575's. I am running 34" pitch 5 blade Herrings turning in. The boat runs great, jumps on plane and I have seen over 115mph. I have blown the XR's a couple times now and am trying a set of Kryogenic frozen gears this summer and keeping my fingers crossed. I am trying to save my pennies and eventually get a pair of Arnesons.

Just upped my membership. Here's a few pics!
Pics 1 & 2 are from Nov. '07 when I bought the boat. IT is an '03 that was Donzi's in house boat until I bought it.
Pic. 3 eventually led to pic 4!
