Ok guys, I just got a chance to go out today and test the ski since putting the 13/22R impeller, Jims ride plate, Leo's Wedge, intake grate, pump seal kit and filling ride plate holes, etc. My ski ran 68mph stock, I did ribbon delete, exhaust, Riva intake and anti cavitation cone and speed dropped to 66mph all over the limiter and cavitating bad out of the hole. Today air temp 90*, water temp 74*. Full tank of fuel and I weigh 225. My ski still had slight cavitation on hole shot but probably 80% better than what it was. Top speed on my GPS was 71.4mph on 3 runs. Borrowed my buddies GPS and his read 72.1mph on 3 runs. I'll take the highest number... Lol.
