    There is a plug in the nose cone but that's just for refilling. You remove the cone(three bolts) to drain the oil. Be careful not to pinch the o-ring when reinstalling.

    Pull the steering and trim cables. Pull the reduction nozel. Remove the cone and elevate the nose of the ski. The oil will flow out. Check for water in the oil. If oil is clean reinstall cone(carefull with o-ring).

    -if you can preasure test the pump w/threaded pop-off tester.

    Fill the cone w/80W90 gear oil (about 3-4oz). Wrap the plug twice w/teflon tape and reinstall.

    Add the oil slow to let the air out and I use holymar thread sealant for the plug.

    Thumbs up Thanbk you...

    thanks guys,that makes it alot more clear to me.however my ski is in my brothers heated garage ona stand i made for it so i cant actually elevate the nose up to get the oil to drain out. so should i wait till i put it back on the trailer in the spring? or will the oil still flow out enough?
    thanks again for all the help.this site is the best!

    Majority of the oil will come out when you open the tailcone,I put tinfoil underneath to catch oil & flow towards a small oil catch pan.
