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.

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!
