I Have this 2003 seadoo gtx limited supercharged 4-tec I am trying to figure out why this blew up and where the piston went. I think the piston chunks must have gone out of the exhaust and the whole but the whole is not that big and does not go all the way through to the outside of the case. Any Ideas on what happened and where I can get a new engine from besides SBT would be greatly appreciated. I don't want SBT because there is a whole in the bottom of the cases and they will charge more for a bad core.
