    Does anyone know the specific prop size for a 2000 43 foot Ocean with Volvo Power. Can't quite make out the markings on the props. Think it might be Michigan Wheel 4 blade, Ni Bral, 24 x 20, not sure about the cup. Any info would be helpful. Thanks.

    Hi Rick, according to the manual I have it shows the prop size for the Volvo powered boat as 23 x 33 4 blade nibral with 1.76:1 ratio.
    I have also attached the boat test charts with the volvo numbers, which appear to be a bit optimistic

    Rick - your boat surveyed in Dec 2014 with Michigan Hy-Torq 4-blades at 24x30.5. A prop shop would have to measure the cup. Record your max, fully loaded RPM with the current wheels before you consider a change in diam/pitch/cup
