If you have the right tools ahead of time, this is a 10 min job.

The oil and filter should be changed after the first 10 hours, and every 50 hours after that for optimal engine protection.

Yamalube 4 is the stock oil, Valvoline 10W-40 is also highly recommended.

A suction oil pump is recommended for oil removal. Drill units can work, however you need to make sure the tube you use is going all the way into the oil resevoir. Suction units also make it much easier to tell exactly how much oil you got out.

The stock filter is a 65mm, most aftermarket replacement units are 67mm. A 65mm/67mm combo cup adaptor is recommended for filter removal/installation.


Step One is to idle the ski for 5 minutes on the hose to heat and disperse the oil.

Step Two is to remove the oil cap and suck out all the oil you can. Make sure the suction tube goes all the way to the bottom and doesn't get hung up on a ledge inside. You will get out just over 2 1/2 quarts.

Step Three is to remove the old filter. It is located on the left side of the ski near the rear, under the airbox. You can remove the airbox cover for easier access. Simply slide the retaining clips back around the sides of the cover, remove the two center screws and pull up. It's rubber sealed and may stick a bit. Use the ratchet and cap tool to remove the old filter, placing rags under it to catch any dripings. Once you get the filter loose, screw it off by hand and tilt it up to make sure it doesn't spill.

Step Four is to install the new filter. Coat the new filter's rubber gasket with fresh oil, using your finger. Hand thread the new filter onto the engine and tighten to snug with the cap tool. Remove the rags from the hull and wipe up and drippings.

Step Five is to refill the oil resevior. Check your suction pump to verify how much was extracted, and refill to just under that amount. Replace the cap, and start the engine at idle for 5 seconds to distribute the oil to the new filter.

CAUTION: It is very important on these models NOT to overfill the resevoir, in fact, I wouldn't even fill to the F mark on the dipstick. The units come stock about 1/2" below this mark, and that's where I recommend it be refilled to MAX.

When these units are overfilled, oil will be blown out the breather tube into the airbox. It will coat the paper filter element, ruining the filter, and bringing performance down due to lack of airflow. New filters are $120+.

Step Six is to check the oil level and top off as needed.

Button the airbox back up and you're all set!
