Troubleshooting Rotax Jet Ski Engine -- Oil in Exhaust
 

It's a '94 Sea Doo XP--has given years of reliable
service. If I read the shop manual correctly, the
engine is a Rotax 657.

The ignition failed and I fixed that with a new CD module.

I started the engine briefly to see if it charged properly
since I'd been in the electric module. I ran it maybe 15
sec with no water. I've done this before. Lots of smoke.

There was raw 2 cycle oil (the kind I use is black)
coming out the water exhaust port next to the jet drive.
I also detected a drop of the oil on the fitting where the
exhaust manifold drain connects--it goes to the water
exhaust port.

Before I put the plugs in--while I was checking to see that
they sparked, while cranking--I noticed there was some oil
coming out the plug hole. It looked diluted at least.

Have I hopelessly busted this thing somehow?? Is
there a better forum to ask this Q?

As long as there's no little pieces of sheetmetal from the stupid rotating
intake valve....he'll be fine...(c;
