    Wear ring

    Can the wear ring die in about a hour of riding? It went 68-69 on GPS and the next outing it would only go 60. It doesn't seem to cavitate out of the hole.

    You may have sucked up something soft, like some reeds or waterlogged sticks, wouldn't be catastrophic, but could still eat the ring and/or torque your prop. I'd get in there with a flashlight at least, see what's going on. Pulling the prop isn't a huge job, could have it checked.

    I sucked up a something maybe a waterlogged piece of wood ...it bent my prop RPMs were great lost 8 mph...no cavatation means wear ring is probably ok ...also check your pump seal...

    X2 on checking the pump and impeller intake grate for debris.

    Also might be worth checking for any boost leaks in your charge hose.

    Thanks for the reply. Would it still pull 8k rpms if there was a boost leak?

    No. Free revving on the trailer it would but not under load on the water if you had a boost leak.

    Update. I replaced the wear ring today and now the PX goes 65mph. Still 3mph down from what it did before. It's pulling 8050 rpms. I did see a few small nicks in the impeller See photo (taken before wear ring replacement). These nicks were there when the PX went 68-69 on GPS though.

    The oil is a bit high but if that was the cause the RPM's would be low.

    Maybe there is some drag on the hull. There is some small hard white calcium looking build up on the ride plate. This is a fresh water ski BTW.

    The only thing I can think of is the impeller. Should I go with another OEM one or an aftermarket one?

    air temp ( hotter air temps ) and fuel octane can cause it to run a little slow ( mine runs a little slower with 89 octane , it runs its fastest with 93 ) , and weight of rider all will be something to keep in mind
