2003 Seadoo GTI LE

[JoyRider19]

I just bought this GTI LE for $750 bucks off a buddy of mine. The hull is in perfect condition inside and out. However, the Seadoo when starting gets "hydrolocked" and when I take the spark plugs out water comes out of the carbs slowly while the holes where the spark plugs are throws a watery oil mix. The guy said he left the breather box off and water got in through there. compression is good but what should I do now? Thanks! I'm 19 and have little knowledge of this 717 motor.

To confirm,,,

You are in the lake when it is hydro locking, not the hose. Is the correct?

Well it is just locking up when I go to hit the startt. Battery is just fine and when the spark plugs are out it turns over to crank. So I don't know if it is "hydrolocked" or not I just figured...

Do you have the hose water on and hooked up to the ski when it is doing this?

 

[JoyRider19]

No. my 1996 spi can start without a waterline hooked up and since this is a 2 stroke i assumed it would run without water for a bit.

Oh and if it helps when I start it and it doesnt want to turn the crankshaft it just stops and lets out 1 beep. I hope its something simple!

Bottom line is,,, it can NOT be a hydro-lock issue if there is no water. Since it is not on the hose and not sitting on water, can't be hydro-locking.

I would do a compression test to get a clue to the internal condition of the engine. If there is no water and it is locking up, then something is for sure wrong. Could be oil/fuel or combination of them.

When cranking NOTHING should come out of the carbs. This alone tells us there is likely a timing issue.

Thus, a compression test would be helpful...
