    Ultra 150 = fail

    So the ski breaks down, and I pull the third spark plug because it kept fouling so I figured it was the problem. To my suprize, it was covered in metal shavings.......perfect. I figured I would just have to replace the cylider.

    So i pull the motor yesterday and this is what I found. So thats nice. Anybody have any good contacts with SBT???. lol

    Im going to order the standard motor from SBT and do that my self.

    Would it make sence that it was hydrolocked a week b4 this, and then this just randomly happened

    Yes, that makes perfect sense. It probably bent the rod and the rod finally snapped.

    Thats what I originally thought too. But heres the kicker.

    When i had the motor sitting on the garage floor yesterday, we grabbed hold of the motor and starter to a battery. It turned over fine, everything was moving smoothly. Had the head off cylinder 3, it appeared to operating normally. And the crank wasn't hitting the case where it was broken.

    So I dont know what happened

    Part of your piston probably broke off and was pushed thru the crankcase.

    I don't like SBT motors. theirs a reason they have their warranty.

    Yep broke a piston skirt. When you injest water it is just a matter of time if not cleared out properly. I got a set of cases that look just like that. I would bet the crank is fine. You might be so lucky to get away with cases, piston and a replate on that cylinder if its chewed up
