    Thumbs up Correct prop and RPM"S for your ski

    This is a copy from R&D's Web site on prop pitch and rpm's! Notice just where you should have your rpm's at max. Good Info here for you guys!---------------------------------------------- "The new R&D Pro Pitch Impellors developed specifically for the new Yamaha FZR are here! The Yamaha FZRs 1.8 liter engine platform has low ceiling rev limiter functions that offer an ultra soft cut at 7750 RPM and a soft cut at 7750 plus. The rev limiter functions on the new FZR are almost like traction control, a rev limiter that you almost do not feel in rough water conditions. Engine performance modifications to the FZR add great power and speed, however, peak engine rpms MUST be kept down around 7650 7700. R&D offers a complete custom line of impellor pitch combinations that will keep the engine rpms in check " Tommy Jordan

    Excellent question. I know you can just print them from the online templates but I'd love to have a quality one that will last. If he does make some more I call dibs on one.

    The leading edge gauge only goes up to 14 on my Watcon...I'd definately be interested in one of yours Tommy.

    Great info Tommy 50 rpms is a very narrow range, looks like we'll be repitching a lot this year.

    Sorry about the thread hi-jack Tommy Jordan.

    Maybe you can just make some pitch gauges for us...
