    hello everyone. so i ran my boat today with a 4 blade ss 14 5/8 x 16p apollo and i didnt work so good. wot was 5000 to 5100 at about 42 mph. 5 people, ice chest and other stuff. so from there what sould i go with? a 19p or 20p or what? iam so confused when it comes to props.
    here is what kind of boat i have..........

    1988 miller openbow 20ft
    1997 5.7 vortec with a 750 vac sec holley
    new everything
    omc cobra outdrive 1.43 ratio

    iam looking for a nice 4 blade ss prop that is a all around performance prop. when i got this boat from a boat auction, it had a 15x15p 3 blade on it.

    How much does your boat weigh? how much did all five people plus the ice chest and all your other stuff weigh? will you be carrying this much weight all the time or is this rare. Lot's-o-questions need to be answered before you can come up with the right prop. Do you have a pic of your boat, love Millers, not the beer, the boat

    sounds about right with that load...How much more RPM before it redlines
