Just got my engine and drive installed in my 1995 velocity 280. We ended up going with a blown 555ci with a imco sc drive with a 2" shorty. The motor puts out 1100 horse power the gear ratio is 1.5. leaning toward a hydromotive p5 or a maximus? What do you think?

If go Hydromotive, use the P5X not the P5.

I've always liked the Maximus Labbed after a baseline set of numbers. We have test propellers if you are interested.

I thought the p5 was a bow lifting prop while the p5x is a stern lifting is that right?

bbladesprops

Other way around.

I had a 27 p5 on the boat when it was NA and it seemed to work pretty good.

Velocities have traditionally run their best with Hydromotives. They like the semi clever style blades of the Q4 or P5 design. Too much blade surface tends to upset the boat when it it up on it's pad at speed. The lift created by the Hydro design picks the whole boat up and allows the boat to maintain a more level running attitude while being up on it's pad, thus more control at speed. Lots of speed with your nose in the clouds is not what you want. Believe me, I had a 32 that ran close to 100 and in my experience any big bladed Bravo style prop was a nightmare.

Did you ever try using a maximus prop? What was your x dimension? Did you use a 2" shorty?

stoltz

Brett you were right that maximus has a part number 48-889972-34, but stamp on the prop reads 15 5/8 or 15 3/8 35r
will give you a call on monday. Thanks for your help

stoltz

Brett I will send you the prop on tuesday. i'll make the notes that you requested. Thanks again
