I have read mention of changing the pump oil. What is it, where is it and does my model have it? I read my owners operators manual and I did not see any reference to pump oil. It only references the grease fitting in the rear of my doo.
The pump oil is in the cone at the aft end of the drive shaft
You remove the jet pump (just 4 nuts and the linkages) and then change the oil in the pump. Most buy the SeaDoo oil but some use 80/90 mobil 1 gear (I believe).
You should replace the O ring and you need to use a special sealant on the mating surface. Three screws hold the cone on and then there is a fill port screw.
