    V4 Evinrude 115 prop

    Im running a 20 pitch 3 blade raker with some cupping. I'm getting pretty good lift, I ha sent the boat in a pretty good spot as far as motor height.
    WOT I'm hitting 5800 rpms and a speed of 52 mph. I just know I can get more out of it.
    What is the formula to find how much slip I have?
    Also is there any other props that I could get more out of?
    I knicked a stump while idle this weekend and bent a tip.
    Gonna try to get it sent off. I need some of the experts on here to help me.


    Thanks

    Just my opinion but 52 sounds pretty darn good for a 115. I can BARELY eek out 40 on my 80.
