Proppin my 29 VR1
 

Any body else go through this with a VR1. I would like to buy less then 10 props. I have a 27 Hydromotive P5 prop. 30 quad4 and a used rough 28 Bravo that seems to be the best. I figure the more bow lift it gives is helping out. Anybody run a left hand wheel. Looking to try one next. Looking to sell or swap some of my others. The Bravo got me 81.6@5250 first time out. 30 was 79.2@4900 27 P5 was 80.2@5100.

I ran a lh b1 30p and didn't notice any difference from the same prop rh other than the boat listed to the starboard instead of the port. It was also before my blueprinting.

In your shoes, I'd take that used 28p B1 and send it to BBlades.
Tell Brett you want 2-300 rpm extra and more bow lift with less trim.
Brett knows your boat...

Left him a massage. I wish I had got the right prop from Hydromotive to begin with. I hate having a thousand dollar prop that doesnt meet my needs. The others I bought used so it didnt hurt as much.Why they told me to go with a stern lifting 5 blade is beyond me. I figured they new better then me. But for another $400+ they would rework it and MAYBE it would work better. Great slip factor @7% but not what I needed.

Ask if they will trade it for a P5-X. The P5-X is like a 5 blade Bravo 1. They are a great prop in the rough. I ran one on my 24' Superboat and it was not much slower than the labbed B1 I ran most of the time. There is a fellow here on OSO running a P5-X on his 260 and loves it.

Great prop slip 7%. Leave the prop alone and start adding HP

Hey Zup,
He's got a 600HP/496 so he needs to get the rpm up to 55-5600 to make max power.
I think a labbed 28p B1 or 26P P5-X will do the trick.
My 280 ran 82-84mph with a 650Hp/540. The VR1 is lighter and has less windage so with 600HP he should see 85+.

I have a 509 with 600hp @the crank, less P/S and a water pump.I estimate 530-540
 

The boat holds a kilo record of about 82-83 with an hp500, 470@the prop. Keep in mind it has only about 5 hrs test time after the boat has been rigged. and my trim pump was bad so I had to let off to trim up. Thinking the Bravo1 to Brett is the way to go. but I still want to try as many props as I can.

Yup.
I'd also try to get Hydro to swap that P5 for a P5-X. I think the P5 is only really good on a Cat.

I tried talking to them. Like I said for an exrta $400 they MIGHT be able to make it work better.No trades, No deals. I didnt even get a hub kit when I bought it.

Were you getting a really high prop slip before? Not sure why you would need a 5 blade unless you had a shorty lower. Bblades has a program where you can try a bunch of different props before buying a prop. I concur with Pat, talk to Bret. He might even take your prop on trade. I plan on doing the same thing once I have more money to spend on my boat.

Hydromotive will return your prop for another, I believe there is a nominal fee, there lab finishing price is fairly reasonable at $300. I thought the kilo record was set on a stck 496magHO and not the hp500

Sending BBlades my Bravo next week.


On July 26, 2002, the new VELOCITY VR-1 set the APBA & UIM World Kilo Speed Record. Steve Kildahl and Bob Spitulski drove the record setting VR-1 with a 500 Hp MerCruiser engine that was certified with accurate horse power. The Steve Stepp designed hull out ran all other manufactures' boats including stepped and ventilated bottom hull designs.

In 2005, the VELOCITY VR-1 Team kept breaking that record every year; they toped out at 80.95 mph with an Innovation built 425 HP Engine! Now that's cookin' with grease!! Once again the designed and built VELOCITY hull proved ultimate supremacy against all other hulls, including every "stepped and ventilated" hull entered.


I asked Hydromtive for help and I basically was told it would have cost $400.No returnes or exchanges because I "only" paid $950 through Velocity (no hub) I just wish they had sold my the P5x. It is obvious its the one I needed. What sucke is that after thinking about it I figured thats what he would have sold me. when he told me the P5 I just figured he knew best.

I wish they could sold me this prop.
 

Bob Spitulski, from Chuluota, Florida and Steve Kildahl, from Sarasota drove their new F1-56 VELOCITY hull, propelled by a single Mercury 525 EFI engine, Bravo XR drive and Sportsmaster lower teamed with a Hydromotive 4-blade prop to a sizzling 86.771 miles per hour on the Pamlico River course.

Talk to Mike at Hall propeller. He is the Velocity prop guy. He knows and has run Velocity. He also works with the factory.

and i will bet that Mike at Halls did the prop for this run

Yes he did, I spoke to him today

Went from 79mph@7900 with my 30 4 blade Hydro
 

to 84.4 mph @5000-5100 After Mike at Halls propeller tweaked it. The man knows how to work a prop. Looking to get 3 more mph from a 28. I would have thought Hydromotive would had sold somthing like this instead of a p5. I have a 28 Bravo1 ,28 Hydro 4 blade small shaft welded hub and a 27 Hydro P5 for sale. [email protected]
