    Urgh....I think I am doomed

    Well...I took my jet ski out, well wait.. I attempted to take my jet ski out for the 1st time... And well...it wasn't good....

    It starts....but when you go to take off it doesn't want to... So we brought it back to shore and took the seat off and you could see water gushing in where a crack is. Not sure the part that is cracked but if you're looking at where the spark plugs are, it'd be to the left of where they are (if you're standing at the back of the jet ski looking at the engine)

    You waited too long!

    Last weekend at the Starved Rock, Illinois get-together, you would have had access to all the technical assistance you could ever need! Probably gotten the problem fixed on the spot!

    Oh well, show us some photos of where the water is coming from.

    When did this happen?

    Have you run the engine on the trailer to dry out the engine?

    If not, do it now. You want to be sure the engine is not rusting inside, from the water leak.

    Start it up on the trailer, with no water cooling. Let it idle for a few seconds, then burp the throttle firmly and repeatedly to blow some air through the engine. Don't hold it wide open, just squeeze and release the throttle lever.

    Do this for maybe 30 seconds, then shut it down. Let it sit for a minute or two, so it doesn't overheat, then run it for another 30 seconds or so.

    The idea is to allow the engine to fully warm up, and rev it to maximize the air flow through the engine, which will help dissipate any moisture that may be inside.

    Let it cool again, then spray some fogging oil into each of the carb air intakes, after removing the flame arrestor cover.

    Idle the engine while spraying the fogging oil (maybe 15 seconds of spray per cylinder, alternating between cylinders), then shut it down right away after you stop spraying.

    Let the engine cool some. If you can, remove the spark plugs, and spray some fogging oil into each spark plug hole. Bump the start button once or twice to move the oil around, then screw the spark plugs back in. Leave them hand tight, and do not attach the spark plug wires.

    That is about all you can do in terms of rust defense, until the engine gets repaired.

    I will try to get a pic tonight of it to give you guys an idea of where the water was gushing out at......

    depending on how much water got in the hull you may want to open up the electrical box also to make sure it stayed dry in side.

    It didn't get winterized by who was going to do it. Sounds like it cracked the upper case waterjacket.

    Did this engine also have water cooling for the crankcase?

    Because I am not jet ski mechanical friendly I haven't any idea what the heck a uppercase water jacket is or if it has water cooling for the crankcase...

    I am going to get pic's and try to explain from the pic's the general area where the guys seen water gushing into the hull from...

    As soon as we seen that it was getting water in we got it out of the water and drained it at the lake... I left the drain plug out as I was heading home to let more water drain out and once I got home we have it propped up really high to let the water drain out....

    Ok...Since I am at work I did some searching online to see if I could find a jet ski engine similiar to mine and I found one.. So I have attached a pic... Now looking at the pic you see where it say's "Polaris 750" look right below that... That's the piece where they seen water gushing at on the side of it... (towards the hull) (If any of that just made sense...... )

    That's a '93 750,So I think they did have the lower case cooling.
