2004 GTX RXP supercharged water in oil.

[shaunp88]

Just picked this machine up three days ago. it has 80 hrs on it. Previous owner said it took on water two years ago, said they drained all the water out of the hall and winterized it and haven't touched it since. ( he thinks the shaft seal went bad) I got it home, checked the oil, it looked good.
Problem #1= Put a battery in it, hit the starter button and all there was is a "click" found the starter soleniod under the hood and was able to jump across the terminals and it fired up and idled on about the third crank. I'm assuming the starter problem is either the solenoid or relay.
Problem # 2= after it started I shut it down in about 30 seconds to hook up the hose, before I turned the hose on I checked the oil again to find it "milky." I thought we'll maybe its just a bunch of condensation from sitting for two years. I hook the hose to it, start it again let it run for about a minute and a half. and the oil warning indicator comes on and a solid "beep". Shut it down, check the oil and find it way up over the full mark. During all this I watch the coolant reservoir and it never changes, still at the same level it was before I ever cranked it over. This tells me it water and not coolant. So my question is, where do I start, I ordered a pressure tester so I can test the cooling system, intercooler and oil cooler. If I've read correctly the intercooler and oil cooler are cooled by "fresh water"? Could it be the exhaust system sprung a leak?

“Took on water 2 years ago” and just winterized it and put it away. Jumped the starter relay. Yikes. There is probably a whole lot of corrosion everywhere in that engine. Pull the sparkers check their condition and maybe take peak down the holes. Download a shop manual and start going thru the water flooded engine procedures. Don’t try to start it again.

Yes, sounds like they got the water out of the cylinders, so the engine starts and fuel injectors and spark plugs work, but left the water in the crankcase with oil. It will be a miracle if you can save this engine, but maybe it will be possible following the flooded engine procedure and changing the oil first.

What confuses me is, the first thing I did when I got it home after an hour and a half ride home was pull the dipsick, the oil looked clean, like it was new. I would think if there was water in the crankcase it would have been all mixed together after the ride home?

There is water trapped in the intake and exhaust systems in a water flooded engine. The first warning in the shop manual when dealing with a water flooded engine is to not attempt to start it before you drain both systems. So when you started it you opened both intake and exhaust valves and introduced the trapped water into the engine.

That makes sense, I guess the positive side of it is that the water hasn't been inside the crankcase for 2 years. I'll clean it all out and start pressure testing everything and hopefully find the cause. The previous owner never said anything about it being submerged but we all know how that goes.

Ok here's an update. First thing i notice when tearing everything down is that the support ring is 3 inches away from the carbon ring and laying down under the engine I find the "C" clip, probably explains why it took on water. I did put it back together, not wanting to spend much money on this thing until I know its savable. I Removed the valve cover, everything looked clean. Removed intake, supercharger, all intake hoses, air box and throttle body, there was definitely water laying in the intake and hoses. Pressure tested the intercooler, no leaks. Cleaned everything up and reassembled, ran a bore scope down the plug holes and what i could see of the cylingers they looked good. Checked compression and got right around 135 in all three. Changed the oil 4 times, running it on the hose in between, took it to the lake and ran it on the trailer for 15 minutes, its sounds good, no milky oil and hasn't taken on any water! Nervously I decide to take it for a little ride around the launch, shortly after it gets on plane (around 2500-3000 rpms) the alarm goes off and gives me a oil message and goes into limp mode just briefly. At an idle its fine, try a few more times, same thing, back on the trailer it goes. Get home, hook an oil pressure guage to the port in the rear of the head, start it up and 45lbs at idle, give it some throttle and it drops then comes back up when you let off. Any ideas?

Oil filter contamination if you haven’t changed it, and also make sure you don’t have a quart of water in your muffler. Service manual states to drain exhaust also. You should only have to change oil once if all water is drained and then a boil out. Check quantity and quality again. Oil pressure regulator sticking could also cause this from contamination.

Muffler was emptied, I did do the boil out at the launch, the oil level is just below the full bend on the stick and it is clean and water free. I checked the oil filter to make sure it wasn't collapsed before I checked the pressure, it didn't have a speck of anything on it. I was reading about the regulator, I guess thats my next move. I have not been able to find exactly what the oil pressure should be, I cant seem to find it in the manual?

 

[skiasylum]

I read somewhere between 25 - 60, min 25 at idle and should increase with RPM, not sure how the warning is triggered

Ok thanks! I did see in the shop manual the oil pressure switch is triggered under 23psi

I have the same jetski and the same problem that you have, I cleaned everything and when after 3 minutes I have the same alarm

I have not dug into the oil pressure regulator yet, as suggested in an earlier post. I'm hoping its that. I will post results as soon as I can find the time to do it.

I fixed it today, my mechanic plugged the connector sensor TOPS valve wrong way.

Fantastic!
