Similar question as Baja Im having built a 30 Y2K Superboat 4600 lbs with a Merc 525 John Cohen(the builders ) sons boat same as Mine being built had a 525 turning 5300 with a labbed 28p labbed bravo and running 82ish. I will be putting the Merc ITS 71/2 in extension box on the boat as well. Everyone says bowlift, bowlift, bowlift. What are your thoughts on the P5X labbed 28, or a 6 blade.

The 5B and 6b propellers work well on the Fountain and the Superboats. The P5-X is a full lifting propeller and the 6B H-6 is a stern lifting propeller. Please feel free to call and I qwill be happy to go thru your set-up with you all and help determine which prop, P5-X or H-6 will acheive your gols!

Good afternoon Julie, The 6-blade prop really interests me. Especially with your comments about how it really works well with a cat. I am completing a motor change/upgrade to my 31 Awesome. My concern is this, does the 6B need as high of an X dimension as the 5B? I had talked to you last year, and you had told me then that my X may not be correct (too low) in order for the 5B to work properly. New set-up is a pair of 502's with 525 hp each at 5200 rpm. Bravo I drives with 1:50 ratio. No nose cone used.

For a base line, the boat previously had a pair of 310hp merc's running at 4600 rpm at WOT. Same drives using Bravo I (not labbed) 28P props. NET was 70 gps mph.
Would an accurate X dimension be needed here for your recommendations?

Is the Hydromotive H-6 available as a standard prop or just lab only. I like the strength of the standard props.

Viper7,

The Hydro H-6 propellers are CUSTOM. They are lab finished but we certainly can talk about the blade thinkness being custom as well.

I am not sure if I you responded to my question. Would a 38 ft pleasure Fountain benefit from these props, or are they designed for the lighter race boats?

Julie, Will do. It will be about a week longer for my outdrives to be back from being assembled. I can then measure for the correct X dimension. I will call then and you will have all (I think) information necessary. Short of knowing what the new motors would use as far as a bravo 1 prop at 5200 rpm. In speaking with Jim Jones previously about HP vs. props, he had stated that a HP525 used a 32P bravo 1 std. prop to achieve the correct WOT rpm on the 31 boats. Talk to you soon.

Hello Shane B,

Nice to see you here! So when are we bolt one on your boat? Your boat has been dialed in around a Herring so it might take a little work but......
