    I guess they had all your answers. I have one of the old ones from when Ron had a partner in another shop. I got a new 5 blade coming as well.

    What is everything they do better? I have always wondered and been interested in trying a 5 blade.

    the everything I'm think'n...

    get on plane quicker..

    stay on plane at slower speed..

    run a faster speed at 3000 rpm..

    accerate quicker...

    have a better slip number

    and go faster top end...

    when I get the props on I'll let you guys know...


    anyone that has already changed to 5 blades??????

    Steve!

    I have tried both on my deck boat and I prefer the 5 blade. I currently run a Maximus 28 and I have tried Bravo 28's and 30's. The 5 blade accelerates much faster. No doubt there is more stress on the drive but knock on fiberglass.... all is good so far. I would like to try a p5x hydromotive because I heard it is a bow lifting prop. There are adjustments that can be made to the props such as cutting down the diffuser rings to reduce stern lift thereby increasing bow lift to assist in "airing out" a hull. I like the 5 blade so much more than the 4 blades that I am willing to risk the drive explosion everyone has warned me about. My decision was made based on reading countless entries on OSO. Alot of the offshore guys run 5 blades with no problems with XR's. Let us know the results!

    the stories I was hearing reminded me of when they started going from
    3 to 4 blades....

    I put the 5 blade 26 on and could only spin it 4500 rpm @ 70 mph

    too much prop for my 496 ho

    I run a 26p p5x on a 28 Nordic Heat with a Whipple 496ho and a xr drive at 5400 rpm. The prop works very well on the boat and does give very good bow lift. I like the Hydro's better than the Max's just because of the 15" dim compare to the 15 5/8" on the Max. Yet I have never tryed the Max prop. I tryed the Hydro frist and it was so perfect right out of the box that I never went any further. BTW I have a 12.5 to 13% slip that also helps keep the xr alive. (a 28p 4 blade bravo spins close to the same rpm at almost 20% slip)The Nordic's have high than most X dim. Just my 2 cents

    Yea right there the best numbers I have seen is 78.3. But this has only been done a half a dozen times. It was a light load early in the spring and not everyday real world boating. The boat runs 75 all day long in the heat with fuel and 4 to 5 people at 1500+ feet. But I added Lighting Headers this winter so we will have to see what it will do this year??? I really hope to break the 80 mark????
