    2000 polaris virage tx resonator melted.

    My resonator melted, could it have been from some weeds on the intake? I put a new one on and it gets hot to the touch, is that normal?

    Welcome to the Hulk!

    Check that the cooling water intake screen, located inside the jet pump main nozzle, is not clogged. It can be hard to see, as it is fitted into the side of the nozzle, on the inside. Last picture, circled in red. It is on the inside of the square area.

    Also, remove and check both end fittings for the exhaust water injection system. One end will have a metal mesh screen, that screen needs to be clean and clear. The other end is just a small hole for water to flow through. Make sure that hole is clear.

    See attached photos for a guide. Yours will be similar, but maybe not exactly the same.

    if the exaust water injection is unplugged from engine could that cause catastrophic engine failure?

    Welcome to GH nutthouse!

    Exhaust water injection is used to help keep the exhaust manifold, waterbox and exhaust hoses temperatures all in check. Now the manifolds and waterbox could handle higher temps... think of the manifold and muffler on your car... without the cooling effect of the water injection. But the hoses connecting them and the plastic noise-cancelling resonators... can not. They will blister, melt and fail. There are skis that run dry-pipes though.

    So will catastrophic engine failure occur? I don't think so. But on an engine designed to have exhaust water injection... somethings gonna probably melt without it and then flood the engine compartment with hot exhaust... which could choke out the engine. And depending where the exhaust exits the ski... and where the water line is... a ruptured exhaust could possibly back flood the ski.

    Cheers!

    Not to sidetrack the OP...

    But what causes the white spots on the jetpump in K's picture? I get them on mine too... in my lake.

    Are they an organic growth... like a barnacle? Or are they a form of corrosion like rust? Or are they a result of a sacrificial anode not working?

    Cheers!

    I think they are Zebra Mussels. They start off as tiny white spots. Feels like sandpaper all over the hull after just a few days sitting in the lake water.

    Intake of air or water?

    Air intake has a flame arrestor, metal mesh 'air filter' bolted on top of the throttle bodies.

    Water intake has a postage stamp sized plastic mesh screen inside the primary jet pump nozzle, right side.
