    Remove and inspect the mesh filter and orifice for the exhaust water injection. This is the small diameter water hose that loops across the top of the exhaust pipe. The screen filter is threaded into the exhaust water jacket. At the other end of the hose make sure the small diameter orifice nozzle is not clogged.

    This exhaust water injection is what cools the exhaust going into the water box.

    Remove and inspect the interior of all the large exhaust hoses. If there is significant surface bubbling or hose wall delamination then the hose should be replaced.

    There is also a small screen in the pump nozzle, this can get clogged if weeds are present, if you are overheating the exhaust you can be overheating the engine which could cause the ski to limit rpms.
