    Prop ?

    What do the two numbers mean? I have a 13-17 and a 14-18. Not quite sure what the numbers mean... thanks bob

    The first number is leading edge pitch. The second number is trailing edge pitch.

    The 14/17 is a steeper pitch impeller than that of the 13/17.

    If you had cavitation on the hole shot with the 13/17 the 14/17 would help prevent this problem.

    I see you have an RXT. Depending on mods, the 14/17R is the impeller you will want to go with.
