Oil Change on The Seadoo Pumps

It is in the Manual that you change the Oil in the Pump each Season. It is good to do this when you are doing the Winterizing for the end of the Season. This is how to do it. First thing it doesn't matter which Seadoo it is you basically do the same thing except for the 4 Tec's that don't need this type of service. Take the VTS or nozzle off the back of the pump first. Undo the steering cable by removing the 6mm nut and bolt and then pull the bolt out. Then disconnect the water lines to the pump and then bilge system that are located inside the hull. Remove the (4) 17mm Nuts that hold the Pump to the Hull. Make sure not to loose the washers or lock washers. Then depending on the model some pumps are silicone in and some of the newer one's have rubber seals with grease on them. Either way you need to pull the pump off by pulling straight back. (If the Silicone is on you may have to make a pulling tool that I have made before. It is (2) 2X4's with holes drilled where the pump nozzle would bolt to and using longer bolts and washers you can pull the pump off. Make sure the bolts are in enough threads so you don't strip it out. You can call me if you feel you need talking through it.

You can also pry with pry bars at the bottom of the pump where the springs for the reverse gate would go. Be careful not to apply too much pressure as you may break that part off. Now that the pump is out, take it to the work bench and have it sit Impeller side up on a plastic box (I use a ratio rite cup) then take the (3) bolts out that hold the back cap on and drain all the oil out of the pump. After about 10 minutes it should be all out. (Warning that stuff smells, don't do it in the house. At this time I clean the rest of the oil off the impeller that might of dripped down on it. Then I inspect the Oil for any water. If water is present I take the Impeller off (Impeller tool required) and then replace the front double lip seal in the front of the pump. Inspect the entire pump, wear ring etc. Once it all checks out you can put the pump back impeller side down and put some of the Seadoo Synthetic pump Oil in the pump until you can see the oil just about reach the top of the air holes you can see. Apply lock tight on the rubber o-ring on the pump cone and some around where the cap matches the pump and re-apply the pump cone and tighten the cap bolts. Do not over tighten these, as the cone is plastic and can get warped.

Open the inspection hole on the cone and put more oil in there. Check your manual for the amount to put in but about 3oz. will do. When you put the filler cap back on make sure to use lock tight again, then I sit the pump impeller side up for a few minutes to make sure there are no leaks. Then install the pump the reverse as how you took it off. If you have silicone on the hull remove all the old and re-apply new to create an air tight pump install. The newer pumps have seals that seem to work good also.
