    300/440/550 performance help

    That prop should be fine, a 13/16 might have a little more bottom end punch but either will work fine. Boring the pump nozzle involves enlarging the opening on the back of the pump, the nozzle is the tapered part that the plastic steering nozzle is bolted to.

    An aftermarket prop will make a noticeable difference, along with boring the pump nozzle you can get a stubby pump cone to give you a little more bottom end.

    300/440/550 copper head gasket good to use??

    Should be fine since the factory kawi gasket was only.010 thick. Are they recutting your chambers too? The 550 reed motors were pretty close to the limit on pump gas compression from the factory. If they mill alot off your head you could be to high on compression

    Super Jet Ride plate problems..........what ride plate?

    I had two bolts come out of one side of my rideplate last weekend. I kept having to fight it to go in a straight line, it must have been dragging in the water and acting like a rudder. I'm lucky it didnt rip off and end up in the bottom of the lake.

    300/440/550 copper head gasket good to use??

    A copper head gasket may increase the compression to much if your haveing the head milled. The copper gaskets are usually pretty thin compared to the factory ones. What kind of ski is this on?

    300/440/550 New ski. General questions.

    If it has been sitting for a while it would probably be a good idea to rebuild the carb, the rebuild kits are fairly cheap. An aftermarket flame arrestor would help out some with the aftermarket exhaust. The prop is a Skat Track prop, mariner inatke grate is aftermarket, and it looks to have a...
