    do they make pistons with enough valve relief to not bend the valves when your having to much fun? its piston time for me yet again... this is the last seadoo i'll own

    Something went thru it. What did the sparkplugs look like? Did one get smashed?

    Did you figure out what happened to the engine? Why the timing chain broke? Why you had water in the engine?

    like vspec said, it really looks like something went through that motor. if it got caught between the piston and valve, that could be what broke the chain. do you have a modified throttle body . if you do, check and see if anything fell off of it. it has to be after the ic since that will usually block anything if sucked into the intake. that's not lean or detonation.
