    Re: 2002 Sea Doo XP Over heating?

    I think I found my issue but I wont know 100% until I get a new nozzle.

    The hose/line on the right is blocked and I've tried everything and cant remove it.
    Do you guys think this would make the ski run hot?

    That's the lines for the bailers. Propulsion water flowing past the tube ends creates a slight vacuum, which siphons out the bilge when running.

    Re: 2002 Sea Doo XP Over heating?

    Can u go back to the water diagram on first page and hook up the hose to your ski at the back of the pump.But first remove Hose #13 running from the rear water valve to the mid pipe and run it overboard as this is what fills the exhaust up with water when the engine is not running
    Dont start the engine...
    Turn the hose on full, you should have water coming out of the pump next to the impeller,pisser and #13 hose (which should be overboard) as well as the rear of the pump shooting out the back next to the VTS trim rod
    IF you dont have all of these,start by removing the hose #28 under the pipe at the front and turn on the hose, if no water comes out the hose is blocked,if you have water coming out reconnect then proceed to remove #28 from the top of the Head fitting,if no water you have a blockage in the engine/pipe,if you have water coming out re connect and proceed to the jet pump and see if you have water coming out of the both the grate and rear where the impeller sits.
    And with the water on from the Hose pull the larger hose fitting off #29 (lower one) at the water valve on the water box and see if you have water coming out as well.And pull #13 off at the top of the pipe and and the water fitting next to the MPEM to check flow

    Re: 2002 Sea Doo XP Over heating?

    ok, #28 Bottom of pipe, has water flow while on the water hose only. Zero water flow while in the lake.

    The head fitting, water flow while on the hose and while in the lake.
    #29? is the feed on the Cases on the back side right below cylinder? If so this has water flow while on the hose.

    #13 fitting towards MPEM has water flow while on water hose.

    The ski runs great and cools perfectly while on the water hose.
    You wrote this awhile back, to check if this is happening see below
    Can you pull the 12.5mm hose of the head (#28) and the 12.5mm hose going to the bottom of the pipe
    Place the garden hose onto the Head fitting (#10) and turn it on and see if you have water coming out the exhaust fitting (#6)
    It seems like you have a blockage in the water galleries if no water comes out

    XP Head.jpgXP #5 zero water flow.jpg
    XP #29 zero water flow.jpg


    Ski was on the hose in these pictures and there was zero water flow. Fitting #5 side of pipe, Fitting #10 head, and line #29 going to pressure regulator. I also pulled line going into the head and sprayed the water hose while the line was removed from the bottom of the pipe and there was no water.

    SURFnTURF what do you think?

    IM guessing there is a blockage in the head???? I stuck a piece of wire in the fitting on the head and it went in smoothly.

    Thanks for your help!

    If you blow air in #10 do you feel anything from #9? You wonít get water at #5 while #29 is disconnected or not flowing. If Iím reading the diagram right
