    96 XP fouling

    New to Ski's this year, bought 2 96 xp's in May. One ski runs flawlessly (well slight hesitation when going on throttle). The other ski runs great and then just fouls a plug. No rhyme or reason, sometimes while running moderate throttle, sometimes while just idling in a no wake, sometimes wide open hauling a$$. The Ski runs great and then just fouls a plug. The problem has progressively gotten worse to where this weekend I used 6 plugs in 1 hours time before I got frustrated and pulled it out of the water and went home.

    So where should I begin, what should I be looking for. Again, newbie to ski's.

    Thanks for any information or direction you can provide me.

    Scott

    Do the voltage tests on the batteries running and not running to see if the charging system is putting out the correct voltages. This can make a motor foul sparkplugs.

    Also, never buy a used 10 year old Sea Doo and go ride it without cleaning the carbs and the fuel selector valves, as that sends so many motors to an early grave.

    Re: 96 XP fouling

    Bill, thanks for your information...........Is there a link anywhere or a how to to point me in the direction of checking the things you've stated. As I've said, Watercraft newbie here, so beyond adding gas an oil, I've not touched a thing.

    Is cleaning the carbs as simple as just removing them, cleaning, and reinstalling? Will they need re-adjusted, how about the oil injector pump, any need to adjust that (scared of leaning that out to much). I'm willing and able to learn if someone points me in the right directions. As I said, it runs great, then just fouls a plug and sputters.

    Info is greatly appreciated.

    PS...........787, all stock as far as I know, couldn't tell you previous service records, ski's are very clean and excellent physical condition, look brand new on exterior though I know that has nothing to do with mechanics.

    Bill, also like to note it only seems to foul one plug, the front one. It will still idle and get me to shore, it will start without hesitation with the fouled plug, it just idles real rough. Change the plug and away she goes till the next time.

    If i were you i would not ride it until the carbs are rebuilt, gas lines changed, otherwise you will need a new engine instead! Check out the sticky on the top of the page there are service manuals available for you to download! Good luck.

    Re: 96 XP fouling

    Sometimes just clipping the sparkplug lead for a new connection at the sparkplug boot is all that is necessary to stop a sparkplug from fouling. This takes 5 minutes and costs nothing to do but a tye-wrap on the 'plug wire boot.

    Sometimes it means the needle valves are leaking in the carbs or the compression is low on one clyinder...........or the exciter coils on the stator are weak. Guessing is a waste of time.

    Thanks for your help, In your best guess "start here" recommendation, where should I go first?

    Re: 96 XP fouling

    I allready told you what I would check first, and it costs you nothing to test the voltage.
    Then I believe I suggessted to go through the fuel system.........
