Gray Crap Comming out of exhaust.

2002 Sporster LT

Fired up the boat out of water this past weekend after the long winter to find that one engine is spewing out a Gray oily substance from the exhaust.
Anyone have any ideas?

Thanks,

oil/water possibly?

Yep, its oil and water. but is it an issue? and where is it coming from? Does the oil mixture need adjusting?

The first time I turned over our speedster after we bought it I had a little of the same. Possibly due to oil sitting in the engine for a time and turning nasty. I ran bot engines on the hose for about 5-10 minutes and haven't had any issues since. Is this a continuous problem you are having?

 

[sea_doo_man]

yeah, It was doing the same thing last year before i winterized it as well.

Possible that the oil injector is getting stuck open and letting to much oil into the engine. Could be a bad seal.

Does the engine having the problem still run as strong as the other engine? If not you might want to consider a commpression test.

I doubt it's the oil injection but check that the alignment marks are lined up at idle. If problem persists because of too much oil and your engine has a rotery valve it could be a leaking crank seal allowing oil from the rotary valve chamber to leak into the case.
