    B-kit prop pitch w/ 15-19r, Info needed.

    Guys I am installing my 15-19r with my SS ring and need some info.

    I wont have time to tweek my ski for the up comming Texas event, so can someone help with what there opinions are with my set up and the Riva prop.

    Riva ECU, Pro IC, B-kit, RR thru hull, Riva valvetrain. 4in rear intake, & 81mmRing.

    Should I add 1-3mm first? I really wont have the time to pull the pump
    and retest as my ECU will be back from Riva Thursday. So I need to be as much on when I install it.

    Also this SS ring is dam near touching my prop. WOW.

    Please help with ya'lls setups.

    Add 2 mm so you arent all over the limiter for your outing. and maybe bring the rings with you so you can fine tune a bit while there..my 2cents

    Yea, I only have 81-82-83, But Ray (Sundance) is gonna bring some for me. I asked him to bring the 80 & 80.5. So I don't have to ruin my day if I am all over the limiter.

    Jerry added 2.5 mm to mine for the 81mm probably did the same for Rays.
    Ended up perfect with 8550 RPMs

    I am gonna add the pitch today and install the ss ring into the
    Skat triple bearing mod pump. Then pull the skegs off the shelf.

    WOW, I added the 2mm I said I was gonna add and it made my prop look wavy. I know it is gonna look like this, but it just seams like it is wrong.

    It sure does add to the surface area of the prop. I have to shave the outter edges of the prop by 1 to 2 mm a piece to fit in the ring.
