Guys,

My ski got water in the Cylinders, I took out the plugs & the water shoots of of the x3 cylinders when I try to start-How can I "drain" the water out of the cylinders" or can the water be flushed out?

Remove the plugs like you did and crank it until no more water shoots out. Then take it out on the water and run it at high RPMs for at least a half hour. The longer the better. That will burn up and get the rid of the remaining moisture.

But do this today as you only have a small window of opportunity before the water starts to rust the motor internally. Then you can kiss your engine goodbye.

Thanks for the info-
Maybe you can help with this aswell- sometimes the exhaust get very hot, seems like its blocked sometimes with debres or sand etc- when I flush it outside the water the water dont come out of the small round hole under the rear step just next to the exhaust hole- how can I clean or open the watercooling system so that it :unblocks" quicker maybe-

Yes, what year is the GPR? Reason I ask is because when they get older the catalytic converter in the exhaust likes to break up in pieces and clog the exhaust. It happened on my GPR. If this is your problem you have two solutions:

1) Replace the cat with a good used one (unless you can afford to pay something like $1500 for a new one from Yamaha.)

2) Remove the cat and install what they call a "D plate" in place of the converter. Alongside with a special electrical plug that connects to the exhaust temp sensor that tricks the computer into thinking you still have a cat and all is well so you won't get the exhaust temp light.

There is a wealth of info on the internet about this issue. Replacing the cat has the advantage of 50 RPMs higher redline. When you install the D plate because of a drop in back pressure you lose 50 rpm off your redline. The D plate has the advantage of added reliability since there is no more cat to fail and a little weight savings since those things weigh a good 15 pounds or so. Best of luck.

What i've seen people do is tilt the jetskie sideways on land, remove the spark plugs and crank the engine to remove the water as already suggested.... a mod to that technique that i've seen is putting the finger on the spark plug hole and leaving a small space for the water to come out, that applies pressure on the compartment and forces the air+water out of the piston at a higher rate.... The process is done to each piston ...

The only problem with cranking the engine with out the spark plugs is that you gotta have a fully charged battery, because you can really end up draining your battery..

As already suggested, do it as soon as possible, preferably right after the jetskie flips, or as soon as you find out... that is to prevent any engine damages ..
