Need Help PLEASE

2001 gtx rfi first run of the season had no probs. 2 weeks later plugs getting oil on them and fouling out. Replaced plugs they fouled after about 1 hr. Drained left over gas from the winter and put in mid-grade, cleaned Rave's, checked compression was 140 front and back, still had same problem with new plugs. Trimmed spark plug wires back, put in new plugs and verified gap. Have gone out several times over the last 2 weeks in between attempts to fix. Went out for about 20 min today and had to limp back to dock. Made sure all the oil was blown out and replaced plugs. Went out for another 20 min and began boggin down, went into limp mode and then shut down all together. Tried to restart but engine won't turn over and display reads high engine temp but when i changed display engine was 87 degrees. I checked oil level and it was really low, I guess I had run through a lot of oil over the last 2 weeks. Read online it was not the oil but their may be a blockage in the water cooling system. Is my engine shot? Where do I begin?

Your engine could have seized up from using bad oil, what oil were you using?

 

[ryanlowmiller]

oil

xps for seadoo rotax engine

inner seals...

think its time for tear down.

how much should I expect to pay? I can do minor stuff but this is beyond my comfort zone. What does it entail. There is a seadoo dealer that does the work about 50 miles away, any questions to ask or ways to make sure I don't get ripped off?

 

[timmyboy76]

oh, you'll get ripped off, sorry to say. Best thing for you, if you dont think your mechanical enuf, is to pull the motor, pull the pto, intake manifolds, exhaust manifolds, stator..etc, and send to sbt for replacement. Sounds tuff, but this stuff just bolts on.

how long would the shop take to do all this? If it will take more than a week and a half I can have father-in-law look at it for me. Would like to try and do more mechanical things but I am afraid of screwing things up worse. Wish I had taken a shop class in high school. How much would I expect to pay if I just send it off, just a rough estimate would be helpful.

Thank you to all the people who take the time to read and post for the rest of us to learn.

sbt is about 12-1300 buks I think, with 1yr warranty. To have a "dealer" do it, he'll probably use the same company, but charge 2-3 GRAND....

 

[ryanlowmiller]

called dealer wanted $2700 to replace/rebuild engine plus $700 if any core damage. Father in-law opened it up and needs new piston, rings and gasket. said he could do a top rebuild looked on sbt and they have one for $200 something but they ask about oversize piston. Do you have to bore out cylinder or does it depend on condition of cylinder?
Found another site that you send in your stuff and they bore it out and size piston for you?

 

[custompartsguy]

If your cylinders are very lightly scuffed they can just bee honed, but if you need a new top end then you need to have a machine shop take a look at the cylinders and bore them for you, only they will be able to tell you how much they need to be bored out. You can also send your stuff in to be done, its up to you. Take a look at your cylinder walls and look for any damage, that will tell you if you need to bore them.

father in-law said cylinder looks good and so does crankshaft. He does his own maintanence on his 2 jet-skis and has done top end on 1 not sure about the other so I trust him. Said he can get top end for $220 with standard sized pistons. had oil on plugs and fouling prior to piston prob, could they be related? He said it may be a sensor, I know there are 5 on the rfi. Which would be the likely sensor for something like this and would it show up on a scan?
