Milky oil discharge

[clancy]

Hi,
I have a 2000 RX (951CC), and when I was draining the chassis for the season pull-out, and I was dismayed to find about 2 cups of "milky sludge" pour out of my drain plugs. The Seadoo has 100 hrs on it and has run well over the summer. However during its last outing, I did notice the maintenance light blink a few times, and I experienced a "bog" a number of times under acceleration. I pulled the spark plugs this weekend to inspect and found droplets of water on them.
Any suggestions as to what has gone wrong? Feels like I'm going to be at the dealers mercy. Thanks in advance.

hey clancy...do compression test. How mechanical are ya???

I'm mechanical with automobiles.. The compression test is do-able. What are you anticipating with results from that test ?

Thanks for the response

I'll have to take a look .. is parked at my cottage. Will look at it again this upcoming weekend.

Milky mess

What should I look for if it has gray fuel lines ?

Thanks for the input

He's just suggesting your bogs could be coming from a clogged line or filter. The gray fuel lines are known to gum up your carbs. Replace with black fuel line hose.

If you got milky oil, your getting water in the engine somehow. That can caused by a faulty head gasket or cooling water being back up through the exhaust. Do a compression test to make sure everything is still alright with the topend before you out her away for the winter, might have a winter project.

:agree: but chances are that you spilled some oil in your hull, and when it mixed with water it turned milky color. Doing a compression test will give you peace of mind that the internals are ok. The Gray Fuel Lines were on older seadoos and would deteriorate over time and cause a clogged carb problem. In 2000 and newer, the problem is non existent so not to worry.
keep us posted on your progress.

Thanks for the advise. The compression test ran out at 100 and 115 lbs .. I assume that is reasonable for a 100 hr. machine. It does have gray fuel lines. So I think I'll winterize it for the time being .. and wait to see what spring adventures I'll be up against.

Thanks for the advise Karl .. It does have gray fuel lines. The compression test ran out at 115 and 110 lbs, so I assume that is reasonable for a 100 hr machine. I think I will winterize it and see what spring brings.

Compression....

At 100 to 115 psi on the compression test, you are at the lower end of acceptable compression ranges. You'll start to notice the engine doesn't quite have that same "ummph" it once had.

If the milky oil came from the drain plugs, then like Karl has said, you could have had oil from your vent line overflow into the hull and you mixed it with water. That is a common sight in watercraft. As long as it didn't come from the counter balance shaft (which, you should be checking it too!) or a leaky line from the oil injection system. .....You have reed valves, so you dont' have to worry about a rotary chamber.

Grey fuel lines probably the source of bogging. You may have gotten water in the engine during flushing or like nswillin said, through your exhaust system. That's not un-common either, just try and start the engine on land, with no water hooked up, run it a few seconds to heat it up and shut it down. The moisture will evaporate.
