It's a quick thing to change if you decide to do it now.
The Jet Pump oil change;
If you look into the nozzle in the rear of the ski you will see a cone with 3 screws and an oil filler allen screw.
To change it,
1) Take off 4 13 MM bolts holding nozzle and 10 MM bolt holding steering.
2) Get something to catch the old oil in, drain pan or margarine cup etc.... (don’t forget the nose plugs, the oil stinks to high heaven)
3) Remove the 3 8 mm bolts holding the cone on.
4) Pull the cone and drain the oil out. Prop the front of the trailer up as high as you can to get most of it out.
5) Inspect the rubber “o” ring and if it is good apply silicon and reinstall the cone. Make sure the allen fill plug is on top.
6) Lower the front of the ski and add oil** to the cone. When it is full, take a brake and have a drink. There is air in the cone and when you go back you will see that it is low. Top it off and take another brake... do this until the fluid does not lower again. I often start the ski for a few seconds to make sure oil is all the way worked into the bearings and all the air is out.
7) Wipe silicon on the set screw and screw it in (be sure not to run it all the way into the cone. just deeper than flush is fine. Let it sit 24 hours to cure the silicon and put the nozzle back on.
**NOTE: Use Sea Doo 75w90 GL5 Synthetic Polyester Oil, or similar same wt.
