gasoline in my rxp x crankcase

I loaned my ski to a neighbor, I know bad Idea. He told me he accidentally poured gas into the oil fill. He said mayby a gallon went in. He realized what happenned when it over flowed. He immediately took it to a dealer this past saturday and they couldnt get to it till yesterday. He never cranked it up. The dealer said it just needed to have the oil changed. The dealer is telling me know it is running rough. what could have caused this. They changed the oil again and the spark plugs. They are calling me to see how far to go. Cant they just hook it to a computer to see why it is running rough? It was running perfectly before this mess happened. It has about 60 hours on it. Thanks for the help.

As long as your neighbor(or someone) didn't start it while there was fuel in the oil tank, there should be no damage. I would ask the dealer to run a compression test before doing anything, I don't know what the dealer means by "running rough", that's a pretty vague description for a repair shop to use.

Connecting it to a diagnostic code reader can tell you if the ski's computer has detected a problem. Often the codes can lead to the cause, but not always, mostly just get a general idea of where the problem might be.

Im not worried my neighbor ran it I am worried the dealer ran it.

I got my ski back from Dealer Knowing It wasnt right They said it was running rough and to the tune of 85 dollars an hour they would be happy to trouble shoot. They did change the oil twice and plugs once. The oil still has a smell of gasoline. It is also real hard to start. When I finally got it running after about 3 minutes i got a EXHAUST message and it threw out a P0544 code . Can anyone tell me where to start looking and why would it throw out that code. I was gonna pull the plugs and crank the ski to blow it out, clean the plugs and change the oil again. Does anyone have any suggestions for me.

Thanks

Your shop service manual should have all the code listings in it with a brief explanation of what they mean, you really should have a copy if possible beg borrow or steal one if you can, IMO.

I kinda think pulling the plugs and cranking won't accomplish much.

If the oil doesn't feel diluted with fuel you might be good to go it will smell like fuel for a while till you get it running and heated up to burn off the residue. If it feels diluted then erhaps sucking out the contents and putting new in there once again will help absorb most of the remaining fuel. It will take some time running to make enough heat and burn off the small amount of fuel in there, it's most important your oil isn't diluted to the point it cannot lubricate.

Don't think changing plugs is going to help anything, could be the fuel in the crankcase is throwing off the air:fuel mixture to the rich side and causing "rough" running but I kinda doubt it's that sensitive.
Can you monitor your oil pressure, is it normal? That would be my concern, if the oil was diluted with fuel it wouldn't lubricate properly and some damage could result. So yes, change the oil till it's no longer contaminated but I've found in the case of a water sinking diminishing returns after 3 oil changes most of the water is gone (I can no longer see it), so maybe it's similar for a crankcase full of fuel.

Water sinkings are covered in the service manual.

Basically what I do in case of a water sinking is, suck all the oil out and change the filter, look in the filter to see if there's water in there, refill with oil pull plugs and crank, recheck oil and filter for signs of water(oil+water milkshake), usually yes, suck oil out again, drain or replace filter, refill, start up ski for a few seconds, check and replace if water is found again.

Usually after the third oil change there's no water remaining.

If your oil feels good then you might be okay to run it around in the water at lower speeds until the fuel is evaporated away. Oil changes are cheaper than engines.

Oh, also, if there's something being eaten in the crankcase such as a bearings, the pieces will show up inside your oil filter, so if you look in there (some metal spin on types have to be ripped open) and don't see anything alarming, that beats the alternative.
