    Oil Pump ???

    I just put a 785 together with the oil injection and was wondering how can i tell if the pump is workink ,for the first tank i went 40 to 1 inthe gas plus the injection just to be safe . i don't see anymore air bubbles in the lines but when i pull a line off the carbs no oil really come out is this normal or is there something i should worry about .

    Are you pullin the lines off when the motor is running? You should see flow out of the lines at an idle...

    do the same proceedure for my suzuki outboard on the boston whaler bob. also magic maker the tank to make sure oil is being pulled from it (mark and ck at same ski level doooooo)
    hope you used an older set of plugs cause youll probable foul em. after first tank is normally when i put in fresh ones.
    there should be an air purge on the pumb also, see tech section.
    when you run your second UNMIXED tank, if you dont see blue smoke at start and idle SHUT DOWN AND CK!
    glad i could finally give you some advise for a change
    john
    ps oil pump runs only when engine does

    Throw oil lever to full oil and check for excessive smoke while idling. I pull the lines all the time and it's odd how they don't have tons of oil falling out of the tubes.

    Ok guys thanks i'll give it a shot ,yeah can't believe how little oil if any comes out when you pull a line off it had me scared , normally i would go Premix but they seem to bring more money if the injection is still hooked up .

    I prefer pre-mix as well, it's easier, no measuring and no mistakes when a friend re-fuels. As long as you verify the pump is working and you don't need to deliver more than 40:1 all is good.

    Did you mean to say you prefer oil injection?

    I know I am happy with my oil injection.

    Yeah, I started one direction and then changed up.
    Even the Matrix I just sold to Pirate still has the injection system, works killer even at 200HP.
    Of course if it fails, it will get ugly, I change the pumps every couple of years just so I feel better.

    ment i prefer to premix. the suzuki outboard is the only thing that has oil injection and i scares me. alway do a premix plus the injection on the first tank of the season, ditto ck smoke at start up too.
    as for my skis that i got from bob they were delete when bought. positives i see are: less machanicals to fail, less weight both oil and mechanism. more room to work under dah and ft of motor.
    as for friends riding they ussually dont after nailing the throdle once. nieghbor has 2 ancent kaw skis they can use (very mild).
    as for gasing up nobody ever puts gas in them except me and nathan. even have specific containers just for skis. (yep im anal) beside at $80 per fill up and $8 for oil per ski my cheap friends dont even offer! another reason they dont ride um!
    just my opinion like a**holes everyones got one.
