    15f waterbox coupling corrosion repair

    Any suggestion on how to repair a corroded water box coupling? The picture isnít mine but represents similar corrosion. A replacement waterbox is not an option for me.

    There is a stainless insert inside the corroded aluminum ring that you could pop out and measure to cut a solid aluminum part as a replacement for the whole end assembly.

    Alternatively, you could media blast the end, slather it in epoxy and run it until you get a leak.

    Pretty much every waterbox ends up looking like that, I wouldn't sweat it if its not leaking.

    Kawi performance sells a piece of tube for this. Does have to be cut off n new piece welded back on. Or you can measure and get a tube from a metal wearhouse and do the same thing.

    My coupler is still decent. It had some corrosion on the aluminum but the insert was solid. Just added some high temp ultra black sealant inside the coupler to help seal the liner a bit and keep water from pooling up. Should be fine for a few years. I maintain my skis religiously.
