Blue Smoke please help!

[backside180]

Hi everyone.
I'm a new member, long time Seadoo owner. I just purchased a 2001 Seadoo RXDI last week for my girlfriend. The previous owner had passed away and his son was selling it. The ski was winterized fall 2006, and not started until this spring. It ran fine on the trailer with the hose hooked up, and had only 45 hours...looked like new.
I just put it in the water yesterday to take for its inaugural run, but soon ran into problems.
After starting it up and idling away from shore, I noticed a unusual amount of blue smoke coming from the exhaust. I figured it would clear itself in a few minutes, so continued idling up the river.
After it "warmed" up, I tried powering onto the plane, but the seadoo would quiver and shake, blow even more blue smoke, and I was unable to go above 3000RPM.
Put the Seadoo back on the trailer, and pulled the plugs. Black, and soaked with oil.
This thing is oil injected....is there a way to adjust the amount of oil being mixed?
I checked the reservoir, which was filled above the recomended level, but shouldn't affect the ratio.
Why is this thing running rich?
I thought the DI's just worked!
A friend who has owned a few seadoo's told me it could be a dried up seal in the crank case due to the ski sitting for 20months unused.
Any thoughts before taking this thing into a "stealership" and being told I need to buy a new motor.....?
Thanks everyone!

the seals in the crank will weep a little oil over time. they have had 2 years of time. your crank case has a buncha oil you have to run out. if it is still smoking bad after a couple of hours, you might need a crank job. the vibrating was either something in the jet pump or 1 badly fouled plug so you were only running on half the motor. buy a couple (4?) spare plugs and carry the wrench with you. i bet it will clear out. if not, you aren't hurting anything but your pride when your friends see you. heck, you can honestly say you really smoked 'em.

Thanks for responding....
This was the general consensus when I called around to my local dealers .
I ran it again for about 15mins hoping to burn off that extra oil, but it was still smoking and I was unable to plane.
Brought it to the Seadoo dealer this morning and was told that they would need to take the motor out to replace the seal....."very expensive" was what he said.
This was before they even looked at my Seadoo!
Is there any way to drain the excess oil from the crank case?
Thanks

Being unable to get up on plane is a sign you are only running on one cylinder. When doing that a smoky exhaust is normal. I really doubt you need the crank seals replaced-- I would stay away from any dealer who tells you that is needed based on what you have reported here.

Start with at least one new spark plug. Better to just replace them both, but if you want to save buying a second plug for now, just replace one. If no change put replace the other with the plug you just took out. (Heck, you can even use a plug/s from your machine for a test if you want.)

My bet is once you get firing on both cylinders you will quickly be up on plane and the smoke will clear in less than 3 min.

Good luck!

Yesterday, while trouble shooting, I replaced both spark plugs with new ones... This didn't really help out. I rode around at 2900 (max able to obtain), still blowing blue smoke.
When the ski is on the trailer, (not under load) it will rev up to around 5500 rpm.
I've been doing some research, and this leaking crank seal seams to be a common problem after the ski sits for a while.
Is there any way to drain the excess oil that has pooled other then burning it off or opening the motor?
Thanks,
James:cheers:

This is all new to me so I can be wrong. I would give it a compression test first of all. if good compression I would think it may have a fuel injection or compressor problem. I have read alot of bad about the di models. make sure you use the correct fuel also as I read this can cause problems. keep in mind I have only been into pwc's for 5 months part time so I can surely be wrong good luck Robin. :cheers: ps I would not think crank seals as I do not believe this has a rotary shaft chamber

No way I know of to drain pooled oil from the crank case. Pooled crankcase oil sholud quickly clearup. You obviously have something else going on. It still sounds like you are firing only one cylinder. I would be looking for some reason that one cylinder is not firing. You can find out which cylinder is firing by removing one plug wire and placing it on the ground post. Then crank. If fires up, the cylinder you disconnected was not firing before. If it fails to fire at all then the cylinder you disconnected is the one that was firing. I really think you will find it runs the same with one of the plug wires grounded. That is the cylinder that is not firing for some reason. Most likely reasons are bad coil, bad plug, bad sparkplug lead, or no fuel. If you have ignition and fuel to both cylinders it should be running on both cylinders and pulling reasonable power.
