    How much performance loss should I expect?

    How much performance loss would a worn wear ring create?

    My wear ring to blade clearance is measuring between .012-.014 inches. The manual says the max allowable is .014. I changed it today, but I am wondering if this would cause a loss of about 3 mph and 200-300 rpm?

    Absolutely........

    When my wear ring went bad, I lost +-350 rpms..........


    Got tired of paying for new ones and went to the triple bearing mod and SS wear ring

    Please let me know if it helped. I planned on letting my wear ring go this season and then upgrade to SS so I didn't want to pay 50 for another.

    absolutely no doubt about it!! you will lose RPMS with a wear ring whose tolerances are maxed out... i've usually noticed about 100-150 rpms personally

    Well this makes me feel slightly better. I was bummed that my rxp didn't feel as fast as last year and was thinking I had a boost leak or slipping SC. I'll let you guys know my results this weekend.

    How many hours do most of you guys put on a wear ring before you replace it?

    I have 35 hours on my ski. Just rode it Sunday for the first time this year and ran a 68.5mph into the wind at a solid 8100 RPM the whole time, and was 50F out. Its still stock, my signature will be true by the end of the week. Just wondering what my chances are of needing to replace my wear ring this summer . Like I said I've got 35 hours on it now and will probably have close to 90 by the end of the summer.

    I've got 23 hours on mine, but this last trip (the first out this season) was in a dirty lake. The entire no wake zone by the ramp had sticks, twigs, grass, bark, ect floating I know that is what caused the demise of my wear ring.
