95 xp800 not peaing???

[johnny blaze]

my buddys 95 xp 800 is not releasing water at all, after about 10 minutes on the very first ride after purchase, it would shut off and not crank back over, we took off the seat and a bunch of exhaust fumes came out like if there was some stoners in there fogging it out.... any ideas????

If no water was coming out of the tell tale than thats a problem! you say i shut off and wouldn't crank over again.....that could mean it seized from over heating. especially if you took off the seat and smoke came out thats a pretty bad sign. Chances are something is clogging the cooling system ie; sand, debris etc

Yep... sounds like the cooling system is plugged. Because of that you overheated the engine, and melted the exhaust coupler.

well he let it sit for a little bit and it cranked over and then shut off, then he took it home and it started instantly and seemed fine, must be something clogged probably is what im guessing, where would he start looking for the clog, and where should the pee come from??

check for clogs on the intake hose going into the head. there could be something inside the cylinders water jackets clogging also or the head itself.

And to answer your question where should it "pee" from at the back where the hook is, there is a little hole... you will only see a stream of water when you get over about 3000 rpm and thats how you know you got water flowing threw the cooling system while your driving it. hope this helps. :cheers:

alright so my buddy tells me that water comes out the back where the impeller is, but thats it, idk why it would smoke inside like it did, it ran awesome for about 10 minutes, then it wouldnt get up on plane, then it just shut off and wouldnt even attempt to crank over, then a minute later it cranked over and then shut right back off, he got home and it started up with no problem instantly, so i guess it got clogged while he was riding it and it overheated... we will check for clogs and report back with updates, any more ideas would be greatly appreciated

[seadoo/skidoo]

water is suppose to come out where the impeller is because it's a jet. but there is a little tiny stream that comes from a hole about 1/8" big on the back so it might not off been the little stream your buddy was seeing.

And the engine is heat seizing: because you say you leave it for a minute and it cranks over again, well that means once it cools down a bit it is able to crank over again.

Start where the pressure begins, work your way thru each oriface clean/wire all fitting & hoses. The jetpump venturi is where three small
holes in the aluminum let the high pressured water go thru the houseing and then thru the engine. Tie the ski to trailor, back it into the water at launch and start it. You can pull hoses off and figure where it might be clogged. Is the ski Cavitateing? A bad wear-ring will be
cause of low water pressure.

should water be coming out right away ... in mine i notice no water coming out but when i apply the throttle then it pee's

yes water will always come out, but you wont see to big of a stream until you rev it up like you said.

Hey guys thanks for the help its my jetski thats acting up. Still haven't got a chance to look at it yet . When I get off work ill take some pictures of everything inside. Looks like they did a couple of customs things inside the engine bay. Maybe you can tell me if its right or wrong.

 

[Mike Hawk]

Ok so i cleared all my lines. I dont know if the water pump is working

on a SeaDoo there is no water pump. The jet pump is used as the water pump. post some pics of inside the engine bay, chances are if you guys seen some when you took the seat off there is an exhaust hose melted somewhere. :cheers:

the smoke in the engine bay was just because one of my exhaust clamps were loose. now the main problem is that the jetski starts and runs fine on the garden hose and pees, but how do i test to see if its actually sucking without taking it out to the lake. ???? :willy_nilly:

Do you have a pool
If you think you cleared the clog you have it take it back to the lake.
Can't test it on the hose.

 

[seadoo/skidoo]

yup like he said take it to the lake. what i would do is warm it up and than use one of those digital temperature reader and take a reading of the motor. and just feel the motor and make sure it's not getting to hot. also for future reference like I was telling johnny don't run it on the hose for more than a min or 2 :cheers:

The clear tube does the peeing its on top of the motor.


White hole next to jet is where it sucks up water right??

Thats where it pees from

filter looking thing isnt plugged to anything. its located in the front of the jetski.

 

[Mike Hawk]

random bilge pump in the back dont know if it works. green hose is for the garden hose and black hose goes to the back where the jet is. its the little white hole next to the jet in the other picture.

I dont believe the white thing above the jet is where it's sucked up (at least not on mine). I believe it's on the right side, beside the jet pump. in pic number 2 follow the black hose that goes into the head and that will tell you where it gets sucked up..... and that "filter looking thing" is a check valve...... It's not suppose to be plugged into anything don't worry about it.

Nathan

 

[seadoo/skidoo]

actually your right...... in the last pic you posted the black hose does look like it goes to the white thing above the jet pump. I stand corrected

Nathan

 

[Mike Hawk]

I've followed that black hose straight to that little white piece just to the upper left of the jet. but when i turn the ski on i dont feel any suction

 

[Mike Hawk]

lol its alright i just need to know how to test so i don't blow the motor. i bought for 500$ i expected something to be wrong but it runs awesome

That's because it needs to be in the water to create suction from the jet pump as it pushes water. and when you run it on the hose it's basically just using hose water pressure and gravity to cool the engine. but really there is no way to test it. you just have to clean all the cooling hoses out. and lake test it

Definitely going to try it out the jetski tomorrow . Thanks for all the advice and the quick replies Ill post up the results later in the afternoon

 

[seadoo/skidoo]

just try this before lake test:
In the last pic you posted about the random bilge pump: you see that little clear hose that runs over the bilge pump black hose and goes to the back where the exhaust comes out? make sure that hose is not clogged.

also check the black hose that goes out the back of the hull next to the steering cable. it connects to the exhaust pipe on the other end....

and finally make sure the intake hose that goes to the white thing is clean. if all those hoses are clear and it still overheats you might have something inside the water jackets clogged but lets hope not...
