Need help with 94 XP

[BC94XP]

Hi everyone, I'm really new to all this. After lookin on craigslist i went and bought a seadoo down by Lake Stevens near Seattle. The guy said it ran great and all. He started it up and it seemed to run fine. So now my problem is:
Had it on the lake look back and had a huge cloud of blue smoke comin from the back end, no idea where it's comin from. Got it home opened up the seat and the bottom of the seadoo is full of water. After draining out the water I ran it for about 10 seconds and look down near the back and oil is comin out from the right side beside Jet Pump Nozzle area. Is that normal? I have looked under the seadoo and can't seem to find any holes, where would the water have come in? Any advice will be appreciated. Did I mention when I had it on the lake I didn't even open it up I had it goin probably less than 10/km

The water could be coming from the boot around the shaft going to the impeller, or it could be a leak from one of Th hoses used to cool the seadoo. You need to run it on the hose to see where it is leaking in from. Here is some information for running it on the hose. Hook up the hose to the seadoo and have it run for up to 5 minutes. Connect the hose and start the seadoo. Turn on the water after it is started. Turn off the water, than shut down the seadoo. This way it won't allow water to back flow into the engine through the exhaust due to no back pressure from the engine not running. The bearings and seals on the impeller jet pump are cooled from being in the water. When it is on the trailer it doesn't have that cooling effect so they will get hot after about 5 minutes.
I pre start my seadoo's too, dry before I leave for the launch too. Just for a second or 2 to be sure it will start at launch. Peace of mind is worth lot.
Let me know if you find the water leaking problem.

So I just went and bought the flush kit so I could run it on the hose and now I can't even get this thing to start. It just cranks but won't turn over. At one point it wouldn't even crank but I did hear some sort of whirring sound when i had the start button pushed. Any suggestions on what I can check. Thanks in advance.

So I'm still havin the issue of my seadoo not turnin over, I think my batt may be dying soon. I pulled out my plugs and they were covered in oil, any suggestions what this may be about.

Hey BC....whirring sound, may have been starter missed the flywheel, but start with compression test, then rpost, oil on plugs??, if compression good, then oil pump may be outta whack.

So I just charged my battery and tried to start my XP but still nothing, it just cranks. I'm sure it's flooded. How do I fix this. My plugs keep comin out wet with fuel on them. Is there an easy way to a gas flooded engine?

Now that you have a good battery charge lets start from the begining. Pull plug wires and put them on the post in the front of the engine the post should have a orange ruber or plastic looking thing on it. open throtal wide open and spinn the engine over to get rid of the excess fuel. Now put the spark plug wires on the spark plugs and lay them on the top of engine and see if you have spark by spinning engine over. if you have spark and you know for a fact that the plugs are geting wet by fuel. Install spark plugs and try to restart. If it does not start then give the engine a compression check. Let us know what you find out. good luck Robin :cheers:

Smoke...

A huge trail of smoke while riding.........lots of oil on the plugs.

Rotary seals are bad.

Thank you Robin! Did exactly what you said and it is now turnin over. Good thing I was about to give up on it. Guess now I can do a compression test on it. When I did get it started it, it did blow some white smoke is that normal or not. What are these engines supposed to idle at rpm wise. Mine is at between 2000 and 3000 rpm.

Rotary seals...

A compression test will not tell you if your rotary seals are bad. You posted that you had a huge trail of smoke. Was it smoke or steam?

If you couldn't turn the engine over, from what it looks like now is a bad battery, then maybe your plugs were flooded from oil while attempting to start.
Engine on the trailer, idle around 3k. In the water, about 1500.

Post your results of the compression, curious to see what it is. Anything over 100 psi is good, but the difference between the cylinders is what is most important. If one cylinder is 110 and the other is 150, then you may have an internal problem with that cylinder.

If you get a start and you have a little smoke, that will be fine as for the year, some leaking of the seals would be expected. But if you smoke the entire time your riding or if the engine wont' turn over and you blow out a lot of oil while starting, either through the plugs or exhaust, then the seals are leaking to bad to maintain proper combustion and you'll gradually carbonize the engine.

Robin has been around for a while, he has good skills in troubleshooting an engine. I'm glad he was able to give you usefull information. Good job Robin!:hurray:

generally these guys will smoke a lot first run of the year. those seals have had 6 months to weep oil. run it. it may smoke for a half hour. heck. your friends will know you really smoked them. might not of won but...my speedster smokes bad first start of each weekend. clears up in 5 minutes. one motor is worse than the other. if it's smokin' you know your motor has enuff oil. don worry be happy.
