    98 GTX Oil Pump working?

    I have just finished installing my new SBT motor on my Seadoo and wanted to test the oil pump to make sure it is working. I hooked up my drill and ran it counterclockwise as instructed in one forum and the oil barely moved in the line. So I installed the pump on the motor and when turning the motor over the oil still did not seem to be moving. With the lines disconnected from the motor, and the motor turning over, shouldn't the oil be squirting out of the lines? Could the filter be an issue? Can the pump be serviced?

    Any advice would be appreciated.

    just get a block off kit for 15 bucks and premix. then you never have to worry about oil pump failure

    did you bleed the air from the pump?

    Oil injection pump air bleeding
    1.Bleed:
    ●Air
    Air bleeding steps:
    ●Place rags around the air bleed screw
    1 to catch any oil that might spill.
    ●Fill the oil tank with the recommended
    oil.
    NOTE:
    If the oil pump is replaced or the oil suc-
    tion hose is reinstalled, bleed air from
    the oil suction hose by removing it from
    the oil pump.
    After bleeding the air, reconnect the
    hose with a locking tie.

    and from another sea-doo manual

    Ensure oil injection reservoir is sufficiently filled.
    Install a dry rag below oil injection pump.
    Loosen bleed screw to allow oil to flow.

    Premix is easy to do.

    but if you choose to keep the oil pump, here is a document to check, set up your oil pump. 3-4 pages taken from the manual of that year.

    MAKE SURE THE LEVER IS IN THE FULLY OPEN POSITION WHEN YOU CHECK THE OIL PUMP WITH A DRILL

    • check for any kinks in the oil line(s)
    • check and or replace the oil filter
    • check to make sure you have oil in the tank

    it doesn't exactly squirt out of the line

    it sort of inches along, perhaps an 1/8 inch at a time. I'm always looking at this too, but I crank the engine over a bunch of times ( plugs grounded and out) to make sure I see some oil coming out of the lines, you'll want to hold the pump cable full on to prime the lines. I also squirt a little 20/1 premix into the carb bodies as I start the engine up for the first time, once I'm scaring off the local wildlife, I let the oil pump take over.

    I've taken to running two houses lately, one to feed the engine and the second to spray water into pump inlet grate.

    folks aroudn here obvioulsly haven't been told about pump oil changes and greasing shaft bearings.

    I did a winterize on a tigershark last week and a whole lot of rusty crap came out of the shaft bearing seals when I started greasing it. Obviously dry for a long time as I used a good 4 oz before I saw some signs of life.

    Thanks for all the responses. I think I got it working now. the bleeding worked. Now just need to lube the main shaft bearings and put the oil pump back on and start it up.
