    I have a 1996 25' Nordic with a stock plain 454. I run 58.8mph @4300 rpm. my prop doesnt say what the pitch is and i bought it with it on. What should i run to go faster?

    That's probably a 24" prop, and that speed sounds about right. If you want to go faster, you'll probably need to add horsepower, and get that same prop turning closer to 5,000 RPMs.

    If it's not stamped on there (look for some numbers on the hub), then you'll have to give it to a prop shop to check the pitch.

    they will usually be the last numbers ex 23p,22p,25p,or whatever size it is
    3 blade mostly run in odd sizes 21,23,25,etc
    4 blades run in even sizes 22,24,26,etc except for the rev 4 series 4 blades they run from 17-23

    If it's a 1.5 drive then that would require a slip number down at 10%. That seems optimistic. I would bet that it's a 25 or even a 26, which could explain why that motor is only seeing 4300 rpm. What rpm does a stock 454 make max power at?
