seadoo xp580

[fishmonger.33]

i have a 1992 Xp 580, and it runs, but i am not getting oil. there is air in the line. i have heard there is a process to get rid of this problem. the oil light comes on and an alarm too when it is started, if i get oil, will this stop. and also, could somone possibly give me a step by step on how to get rid of the air in the line, or get oil to my ski?

thanks

Re: seadoo xp580

You need to bleed the oil pump. On the oil bump there is a bolt you need to loosen. Its sort of at the end of the pump ( dont mistake the bolts that hold the pump on the case. the bolt is at the end I think its a 10mm. loosen it up till oil starts to flow at a good rate. then close it back up. a mirror helps on those skis cause its a fairly tight fit. i hope you have smallish hands
is the air bubble in the main line or the lines from the oil pump to the rotary valve cover? if its the lines to the rotary valve cover those should go away as the oil pump starts to pump oil but it sounds like its the line to the oil pump. There are two main oil lines on sea doos. One goes from the left side of the motor to the oil tank. the other goes from the oil tank to the oil pump and it has a filter on it.

the line from the left side of the ski usually has some air bubbles in it because thats the feed back line from the rotary gear back to the oil tank. thats the reason for the filter. Make sure the filter is not clogged up. it shoudl be replaced at least once a year.

Re: seadoo xp580

sucess on the bleeding, i am getting oil now, but now when i start it it idles ok with the choke on, but bogs down when u try to give it any gas, and i think it just may be dirty gas and dirt in the carbs, can i try giving them a clean without taking them off? how would i do this? as taking them off is a chore i would rather not do.

thanks

Re: seadoo xp580

You cant really clean them on the ski. If you spray carb cleaner all youll do is clean the throats of the carbs but not the innerworkings. You really need to pull off the carbs for a proper cleaning. make sure that the pulse line didnt come undone when you were messing with the oil pump. Youll see a small gray rubber line going from the front carb ( from the square area of the carb) to the case. it may also be loose at the carb so look for a nipple that has no hose on it.
But for a real cleaning you should take the carbs off

When you say it bogs down are you trying to give it gas with the choke still on? that woudl be a reason its bogging not enough air and lots of oil and gas.

Re: seadoo xp580

well, either way it bogs, with or without choke, the choke just keeps it running longer.. and would a clogged fuel filter cause all this, could the carbs be clean?

Re: seadoo xp580

yeah the carbs can be cleaned. There is a small filter inside each carb that needs to be cleaned. Also you may have a clogged low and high speed jet or the Needle and seat could be clogged up. Get yourself a set of rebuild kits. i think they run about 30$ per carb.

Re: seadoo xp580

i cleaned out the fuel filter and took it out tonight, it ran great for about half an hour, then slowly started to bog down more, and i dont think its getting enough oil, the light comes on and off intemitenly, it smokes a tiny bit, but i think it needs more. and im pretty sure the heat sensor is defective also, seeing as how when i start it up the buzzer comes on right away. i am going to look into blocking off the oil pump and doing premix, going to rebuild the carbs, and how do i go about getting a new heat sensor??

thanks for all the help rob

Re: seadoo xp580

your engine is bogging down due to fuel starvation, once you rebuild the carbs and fuel pump you will notice it runs strong, as for the oil I would wait till you do the carb rebuild and see how it is, you can always add a little oil to the fuel say 8 oz to a tank and leave the oil injection on the engine as you need to pull the rotary valve cover to take the oil pump off or to remove the drive gear from the pump,,the heat sensor can be obtained at www.jetkingparts.com new or used they have them.
the fuel lines on those also deteriorate and gum up everything so replacing those is a good idea you will see a goo when you remove the lines I use clear thick wall vinyl tubing from home depo I also add an inline fuel filter after the factory one to keep trash out of the internal filter of the carb.

Re: seadoo xp580

Also if the heat sensor is grounding out it may send the computer in a limp mode dropping the RPMs down. i cant remember if the older sea doos did that But I know my wifes did

Re: seadoo xp580

no they do not have a limp mode but his symptom is definitely fuel starvation I bet if he slows down for a min it will try to go a bit faster and then slow again,, the internal filter is clogged

 

[fishmonger.33]

Re: seadoo xp580

if the internal filter in the carbs is clogged, can it be cleaned, or does it need to be replaced? and i have heard it is a good idea to bypass the fuel selector to avoid more blockages in the lines, is this true too?

thanks

Re: seadoo xp580

you can usually get by with just replacing the diaphragm and cleaning the internal filter if everything else is ok in the carb, the fuel selector switch is known for either obstructing the fuel or allowing air in the fuel line also the factory fuel lines are notorious for gumming up the system and should be replaced and be sure to use good clamps on the suction side of the fuel system as the original ones also allow air to get sucked in

Re: seadoo xp580

update!

i replaced all the fuel lines. which were rotten( especially the pick up lines in the tank) which was why i wasnt getting any gas. i replaced all the lines, and put in new fuel filters. and i am going to try it out tomorow hopefully

i ordered a oil pump block off plate, and im going to go pre mix to keep it on the safe side.

and what would you say a 1992 xp/sp with a decent trailer is worth?

thanks

Not a whole lot. pretty old ski. you may get 700$-1200 for it if its in clean shape and runs well. its jsut a older ski and they are hard to sell compared to a new ski. The area you live in also makes a difference in price. if youre in a state that has a lot of jet ski riding areas and a lot of people youll sell it for more. if youre in a small town far from riding areas youll get a lot less
