need help where to start on props....old props 32 4 blades massaged by throttle up, great improvements but would still tap the limiter..

1.50 drives

new motors make about 150 more, 785 hp 875 tq

im thinking 34 5 blades any help is appreciated

That would be a good start I'd think?

Man that thing is going to be hell on the drives if you're not real easy with it. Sounds like a mean boat.

I've got a set of 32 pitch five blades you can try to see what you need.

What did ya buy?!?!?

thanks guys, not mine and yeah we have been having the drive concern....originally it was a 575 sc boat then the whipple kit added, had some issues so re did valve train and a basic freshen, work was sub par and created more problems, second engine builder found several issues with head work, injectors to small, and blowers worn out, so the hp wasnt sought after, but never turned down lol....Thanks eddie, i think that will give a good base line to start with, I think it should break 100 mph any body else have any opinions on that?

If its a true 785 100+ should Not be a problem.

Better get the SCXs on order!! Just placed my order--- and I am only 650
or you can just buy the 2 sets of XRs I have now.

what gear case style are your xr's i have a buddy with a 42 fountain needing a drive but would need the steering to work his in 05 model year

I've got an XR that will work on the 2005, $4,500 complete.
