    Found lots of water inside the hull after a long offshore trip. Between this and the unsolved cold start and misfiring problem, I'm at my wits end. Anybody know how to go about repairing this? Is this cast iron? Can it be welded? I looked it up and its about $250 new. Shipping something that heavy from the US to here would probably double the cost. I'm a maintenance freak when it comes to my skis. The motor still looks like new. I must have missed this spot when cleaning the engine area.

    A JB weld type of product is what I would try. The porosity if the casting should allow it to stick well.

    Doesnt stick for long, ask me how I know. If its small thread it with an npt plug and smother it in jb weld. Clean with an abrasive wheel the wipe with acetone, then hit it with a stainless wire brush and then put the jb weld on. Otherwise weld it up or buy a new one.

    So I had the bubbly parts go through a steel wire wheel and found two more badly corroded areas for a total of four holes. Had these welded up at a buddy's shop. The welds look good and they now look like this.

    My question now is how do I go about refinishing this? I showed it to a powder coating guy and he said that they don't do exhausts cause they burn up the powder coat. Is this a special type of high-temp powder coat or is it another type of finish? Any alternatives? Thanks.

    I might have forgotten to tell the guy that it is a water jacketed exhaust. Way cooler than a car or motorcycle exhaust. I will talk to him again tom. Thanks, Sean.
