    Thanks guys. I know the fix is probably temporary and I will upgrade the holder when I have a spare $200 to throw at it.
    In the meantime wonít the factory bilge keep me afloat?
    I checked the lines and cleaned the pickup so it should be functioning properly.

    Here's the deal: the factory bilge pump is passive. It only works when the engine is running and the jet pump is sucking water from it. When the holder leaks, it typically allows more water in than the bilge pump can handle. As the water fills the engine compartment, it hits the driveshaft coupling and sprays water everywhere, including the engine's air intake. This eventually kills the engine--and the passive bilge pump. Then you sink. (Actually, it's not supposed to sink if the seat cushion and foam flotation are in place, but you might end up wishing that it had).

    Buy a new Rhaas holder and you will never have to worry about it again (unless an engine mount fails). AND install an electric bilge pump. (It would be a good idea to replace those mounts, btw).

    You bought the highest performance 2-stroke JetSki ever made, and it's over 20 years old. It takes money to keep them running!

    Thanks for the input guys. I didnít realize these things had such a following when I bought them. Sounds like I made a decent decision buying them.
    Youíve talked me into the Rhaas holder. I will get that on its way ASAP.
    Regarding bilge:
    Since the factory pump is poo poo, should I just get it outa the way and use that real estate to mount the electric pump?
    Iím thinking I could use that bracket and fabricate something to hold the new pump securely in the hull. And itís prolly the best spot for it.
    Iím also thinking any of the pumps with mechanical auto switch will have limited lifespan bouncing around down there. Any pump recommendations?

    I run a rule manual pump, i cannot remember the gpm been some time. With a switch mounted in compartment where the key is. I also run blowsion vacate drain valves. I wound leave stock system in place and mount behind battery.

    Wow. Iím not sure how accurate the Speedo on these things are, but my son said he hit 72mph today

    Not accurate at all. They will do around 65

    I let it cure for 48 hours.
    Tested and no more leak! We rode for about 30 minutes in choppy water with a few WOT runs.
    Not sure how long this will last but seems promising for a half-assed attempt.
    Fingers crossed.
    If you can't afford to fix it right, how will you afford to do it over?

    Just thought I would try a fix that didnít require pulling the motor. It worked for a while but didnít last (shocker).
    I ordered a new holder from Rhaas yesterday. Itís parked for now.

    The good news is the ďmysteryĒ ski that I originally started the post about (thinking I would need help) is actually running great, went together with no issues and starts on the first try, hull is dry as a bone and hauls balls.

    I put my bilge pump on the left side, underneath the carbs:





    Glad the other 'Ski is running well. Make sure you carefully inspect the oil lines. Replace them with polyurethane if they are stiff and brittle. Keep an eye on the jet pump, as the bearings don't last long and you'll ruin a pump if they fail. The Triple Pisser Mod is very important so you can monitor cooling water flow to each cylinder. Remove the display and seal the rubber plug on the back, along with the wires, so you don't get water in it when you flip it over. Modifying the trim to get more UP makes it a whole different 'Ski--much more fun! There are lots of other things you should check, but these are the main ones.

    Finally, if you're not getting water inside the hull, you ain't riding it right!
