    its not a lot but its at the level where it probably needs a top end rebuild but that all depends on the compression i guess.

    i am doing a conversion on the same year model ski and it has 136 on it when i pulled it down but i did it for performance reasons.

    100 hours is about when we change spark plugs. At 200 hours take the carbs apart and clean out the little filters, At 400 hours start thinking about a top end, at 800 hours start looking into bottom end and pump bearings

    i was pointing towards the carbs....200 hours in salt water knocks them around...

    100 hours hammered mine and they needed a rebuild.

    when a power valve fails they have a tendancy to fall into the cylinders and cause serious damage


    wave eater clips fix this and cost very little , sub 100.00 with couplers.

    There is a horizontal pin that holds the valve to the shaft/arm. In the course of time, the pin will work itself out causing the valve to drop into your cylinder and hit the piston.
    The waveeater clips incapsulate the pin, preventing them from working out of position. A very easy and must do preventive measure to take. I put my on in about 30 minutes and had never done them before. I could probably do it in ten minutes next time.
