Water found in oil

I have a 2012 Sea-doo RXT-X. It has 92 hours. It was serviced in Dec and sat in my garage until May. Took it out and it appears the supercharger is also bad and needs rebuilding. The Sea-doo service folks also said they found water in my oil. I'm baffled.

What could possibly cause this?

Btw. Compression is good in all cylinders.

Thanks in advance!

What happened for you to take it to the dealer in the first place? How do you know supercharger is bad?
 
The RPM's were fluctuating and revving in sport mode and the top speed was only about 40mph. Didn't know what was going on so took it to the dealer. They couldn't find anything so I asked them could it be the supercharger? This was based on feedback from my last post. They took it apart and confirmed it was bad. It was due anyway I guess at 100 hours.
 
As long as the water did not get into the ski while in your garage somehow, then I am betting you have an Inter Cooler (IC) issue. The water your ski sits on cools the IC, if the IC has a crack in it, then the water will get into the engine....

At 100 hours the SC should be rebuilt, or, at 2 years. I'm guessing that yours has never been rebuilt. Which puts it WAY past the rebuild time...
 
When the SC fails, (or a hose cracks or comes off), the ski will lose about 25 MPH. That should have been the first clue as to the SC needing service.
 
It's weird that they couldn't find anything then they use you're input to find the issue lol. Anyway a bad supercharger could cause these symptoms. Did the bearings drop into the motor?
 
I'll ask them about the IC tomorrow.
The limited speed and revving RPM'S just happened my first ride of the season. It was running fine b4 the dealer did the service so I assumed they screwed something up.
I'll know more tomorrow when I pick it up and talk with the mechanic.
Thanks for all the feedback.
 
So it ran fine when you put it away? Throw some spark plugs in there then post up your results.
 
If I had to guess,,, I'd bet the IC was not winterized properly. If I am correct, it had water in it that froze over winter and cracked the IC. You had not issues when it was put away, but got one over the winter months. Once you splashed it, the new issue presented itself in the form of water in the oil...

So,, where do you live? Did it freeze there?
 
Yes, it was fine before they serviced it which included new plugs. After the winter service, it was put away in my garage for 4 months. I live in northern California so it doesn't freeze here.

The SC itself really can't cause a water in the oil issue. The IC can easily and then it can come in through the SC. BRP had a bad run of IC's, you may have one of them and it finally failed. I'll try to do some digging on which years/models..
 
Coastie,
Please forgive my ignorance, but wouldn't it be the oil cooler or leaking head gasket causing the water in oil, or would it be vice versa?

Those are both possible. But the IC is a known issue.

And I made the assumption that it is water, not antifreeze in the oil as he said water. Since the ski is closed loop the only way water gets to the engine is the IC. Where antifreeze would be the head gasket by comparison.
 
Ahh...water being the key. Didn't think about coolant. Still got a lot to learn about 4 strokes.
So the IC would definitely be a possibility. Makes sense.

I learn more every day,,, I probably check in and read post something like 70-100 times a day.
 
I mentioned the IC (crack) as a possible culprit for the water in the engine. I asked them to please check it. They were unsure of how to do that without taking it apart. GP Sports said they would call BRP for advise. I'm beginning to think these guys don't know what they're doing? :(
 
Well thanks to the advise on this forum RE: Checking Supercharger and IC, the dealer checked with BPR and they admitted to a bulletin on the faulty IC. So BRP agreed to pay for all the parts for the SC and IC as well as the cost to flush the water out of the engine. I only have to pay for the labor.

Thanks again for everyone's support, advice and contribution! You saved me a lot of $$$.

Have a great Summer!

Chris
 
There you go,,,,

And I would be looking for more qualified people to work on my ski,,,

Once I got to thinking about it I figured it had to be the IC..

You saved like $1000 by the way.
