    most of the props have some cast or stamped numbers on them....that should tell you what you have. check on a few of the post below this one and there are some links to help on the size you may need.

    For Prop Needed LOA? Weight? Horsepower?

    For Prop you have- Stamped on Prop or Hub

    New boat, but I'll use this thread rather than start another post.

    WHat effect does the pitch have on the RPMs. Reason is my enigine now will go up to 6000 (which is max on the guage).

    Prop is stainless steel. But I have two additional props with different pitches. Wondering which would be best.

    General rule of thumb...
    Increase pitch by 1 inch = decrease RPM's by 200
    Decrease pitch by 1 inch = increase RPM's by 200
