Newbie hydrolocked engine while flushing

[canadiansam]

Hey all, new to the forums and just got my first seadoo ever this past weekend. It's a 2000 GTX Millenium carbeurated. I love it and had an awesome ride.

When I got home I tried to flush it just to be a responsible owner but it was 11pm at night and being exhausted I accidentally shut off the engine while the water was still running. I realized after 10 or 15 seconds but by then the damage was done. Anyway I used the shop manual and followed the steps. I got the water out, cleaned up the spark plugs, sprayed some lubricant into the cylinders. She's running again!! Now my only problem is the manual says to spray lubricant into the Air Intake Silencer for about one minute with the engine running. For the life of me I cannot figure out where it is because nothing looks like the picture in the manual. Would really appreciate some help finding it.

Thanks!

If the air box is like the di, there is a small tube on the rear side that pulls out. You would spray in there

The best thing to do, is actually get it back on the water and run it.

if you are running in fresh water... I never bother to flush mine. Only when I run in salt.

Easier yet, and better yet, get it back in the water and run the ski for a good half hour cruising around. This will get the block nice and warm and evaporate all the water that is in the hidden little passages and what not. If you don't, it will cause those areas to rust. And the stagnant water can rust the crank, which will destroy itself if it gets rust spots.

And as we all know the 951's do not tolerate water in them. Go out and run it ASAP.
Also the pre 2002 carbed skis don't have the fitting on the air cleaner for fogging you have to drop the air box down enough to get to the carb throats then I use a piece of the 3/32" injector hose to attache to the fogging oil can to get it into the carbs. You can't run it for a minute either to fog because you will burn up the carbon seal.

i don't flush mine after fresh water rides either, I figure it was being flushed during the entire ride...

wrong?

 

[mikidymac]

If you beach yours a lot then it is good to flush even in fresh water to get any sand out.

Thanks for all the responses. So what I gather is this:
1) don't need to flush in future if running in lake ontario ("fresh" water)
2) don't run the engine for one minute without water (as in my original post)
3) Per the response from mikidymac, I have to drop the air box down enough to access the carb throat and spray in the fogging oil. I'm not exactly sure what this means? Is this referring to the two plastic "boxes" on either side of the large black pipe? The original seller told me to remove the black piece (closer to the front of the ski) and turn something (1/8) if I want to increase the engine idle speed. Is this the same piece I have to remove to access the carb throat?

I'm not a mechanic so just learning as I go. Thanks for the help guys, glad to be part of the community.

I owned my skis in Ohio for 11 years, not a single time did I flush the engines. I never had a single repair needed other than a hole got worn in an oil tank. I change one set of plugs per ski in 11 years,,, They just ran perfect so I didn't do anything than run Polaris Synthetic Gold oil (yes, they were Polaris skis).

Update to the hydrolock. I got the water out and took the seadoo out last night. I ran it with the gas in the off position by accident. The engine kept shutting down every 10 to 30 seconds. When I brought it back to the trailer, the hull had about 3 to 5 inches of water inside the bottom. Is there possibly another issue or should I just take it out again and run it on the water properly? Obviously I don't want it to sink if there is another issue.
Also is it normal for that much water to get into the engine hull?

 

[pwgsx]

You need to run it hard for 30 mins so get back out there with the gas "on"

 

[soccerdad]

No, that is not normal for that much water. But I would run it first, then look again. You can remove the seat and run it with the seat off to see if you can see the water coming in. It is either a loose/worn carbon seal, a hole in a hose, a leaking welch plug in the pipe, or a bad water regulator. Or less likely, a big hole in the bottom of the ski... Get it back on the water and flog it so you get all the water out of the motor. Otherwise, who cares if it sinks.:driving:

Bloody hell!

Yet the average Joe (not coastiejoe - see what I did there) who maintains his kit has any number of odd issues.

 

[Coastiejoe]

Too much water in the hull. As noted above, remove the seat and see where it is coming from.

Also, don't run the engine more than a minute with or without water. First, in the hose it is in FLUSH mode, so the water runs backwards and doesn't really cool the engine as it does while on a body of water. Also. Assuming you have a Carbon Seal, they ONLY get cooked and lubricated when in the water.
