    Re: Prop Slip Calculator (202champ)

    Matt, welcome dude, no invading of space!! This is for ALL that want to be here..

    Mike is telling ya straight on the #ers, that is why he didn't tell them to ya the first time, cause they are a little different then what you are running..

    You have a great running prop/boat!!! Most 21"10 Bullets are right at the same speeds as you.. Louis

    Using the calculator, here's what I'm finding....

    2002 Javelin 180
    2002 Yamaha 130 v4
    13 1/4 x 22 (I added one to make it 23 on the calculator)
    5300rpm light (low)
    53mph GPS
    2.0 gear

    Shows 10% slip.

    That about right for this rig? I think the prop needs an inch taken out, but just wanna get some other stuff clear first.

    Thanks

    Re: (volsjp)

    JP, sounds like you need to try a true 25 or 26 pitch prop, need to watch your positive trim. Your slip #er should be more like 12%

    A lot of variables but I would say between 2 and 5 mph.

    took the first step and lowered the motor 1/2 inch to see if that helps.
