Who's tried a Q-iV or X on a Y2K bottom?

I've heard not much diff. than the B1. Maybe a slight increase in top end, and slight loss in cruise.

mY BUDDY GAVE ME A Q-IV 29P I converted to a fat shaft for my XR. It has the diffuser ring on it which he needed to stop the blow-out. He had it on a supercharged 502 in a Donzi 22Zx stepped hull and said it was "the joint". he was running the 90's. I got a feeling its going to be to big a prop for me to spin though the price was right to add it to my collection... I should be ready to do some testing...

Good luck Gary. I talked to FastEddie and he said the Q-IV was the fastest prop for him at one time. Let us here the results of how it feels even if it is to big of pitch. A 29 Hydro is like a 30.5 Bravo1.

I should be meeting up with Pat McPhearson tomorrow to get some testing done..

We tested props today...
With one person and about 50gal of fuel my boat ran 76-77mph @ 4900+rpm with a modified 28p B1.
And topped out at about 75mph @ 5100+rpm with Gary's labbed 25+p Hydro P5-X.
The 5 blade Hydro is an awesome prop. Definitely more lift to the entire boat than with the B1. If it had been a 26p, I'm sure I would have seen the same or better top speed vs. the B1.
Great Day on the water...
Thanks for making the trip down today Gary...

that would be Jim right?

What was the Hydro and what did it run?

The Hydro I tried was OH-Zone's P5-X and it ran great.
OH-Zone ran both a Quad IV and the P5-X.

Oops. Too many martini's for me!
