01 GTX,Water in the cylinders

[28wombats]

So, first time I ever used the water hose hook up, to test the ski after some maintenance, I found the cylinders full of water at the next attempt of use!

I had let the water run a little extra time after shutting off the machine, did I blow the flipping head gasket with too high pressure?!

Never had the issue on the water so I know it happened with the hose. Wonder if it will be alright to run since the water pump won’t produce that kind of pressure on the lake or if I need to go ahead and tear down the head right away. If so, do I need any special tools?

Even after shutting the water off and pulling the hose off via quick disconnect, I blip the throttle at least a few more times to clear the exhaust, ok to do that for up to about another 30 seconds with no water. Then after after its been sitting for about another hour or so before I cover it and put it away, I start it again and blip the throttle a couple more times, then about for the last 10 seconds or so running I shut the fuel off.

Back to your situation, if it hasn't sat too long with water in it, I'd pull the plugs and crank it til the water stops squirting out. Then fire it up and go run it on the lake for a while to get enough heat in it to displace any remaining moisture or water. Hope that works for you, otherwise the engine could be trashed if rust started to set in on the crankshaft bearings.

How long was the cylinders full of water? Pretty much what gguillot said. Get the water out asap and cranked. I would also add to spray a good bit of fogging oil or WD-40 in each cylinder before putting the plugs back in and cranking it up.

Yeah about 5 days full of water. I pulled the plugs, blew the water out (first with the starter then with compressed air), cleaned and adjusted the plugs before re-installing them and started it up. I let it run about 1-2 minutes without water and shut it off.

Sad to say the engine is probably on borrowed time and the rest damage is already done. You can’t let them sit at all with water in them.

Never ever have the hose on when the engine is off.

Don't run the ski without water for more than 30 seconds as 2 stroke engines reach operating temperature quickly, and you essentially have zero coolant to counter that.
Your carbon ring will also degrade much faster in general unless you're actually ON the water, or actively pouring water onto it since it too needs to be cooled, and can not get cooling from the hose

I made the horrible mistake of letting someone tow my ski at a high speed on the water when it broke down 40 miles out on Lake Michigan and this too filled my cylinders with water, what happens is that water inevitably seeps into the crank case and will displace the grease on the bearings and basically where ever

I knew the dangers of the water but unfortunately I was not able to crank out the water until 3 days after the incident as the reason my ski broke down was a failed starter... you need to get that ski to the lake ASAP and RUN it like you STOLE IT for an hour or so to evaporate any condensation left within the crank, its your last hope

I still use my swamped ski today, adding close to 40 hours since the incident, but I'm eventually expecting the worst; have fun!!!
