Fun on the water is only a part of Sea-Doo ownership. The other part is maintenance. Oil changes, for example -- your Sea-Doo needs an oil change after every 25 hours of operation, or every three months. Even if you don't use it, though, it still needs a yearly oil change. Because a Sea-Doo is the seagoing version of a Ski-Doo and powered by a glorified motorcycle engine, you can do your own oil changes with little fuss, muss or bother. Like all boat maintenance, you begin by disconnecting the battery.
Select the correct oil, based on the Sea-Doo's engine. The 130- and 155-horsepower engines use 10W 40 grade mineral or synthetic motor oil, while the 215- and 255-horsepower engines are more persnickety. You must use only XP-S 10W40 mineral oil. You must change the oil filter when you change the oil.
Ensure the Sea-Doo is level before you proceed with the oil change. Warm the engine for not more than five minutes before you change the oil and filter. In the 10 seconds before you shut the engine off, open the throttle until the engine runs at 4,000 rpm. Shut the engine down while it's running at 4,000 rpm. Warmed oil is easier to remove than cold oil and running it at this high speed moves the oil from the power takeoff to the oil tank. Wait for 30 seconds before continuing, to allow oil to drain to the oil tank.
Remove the oil filler cover and dipstick from the engine. Set the oil filler cover aside. Wipe the dipstick with a clean cloth and set it aside. Push the suction tube of an oil suction pump as far into the dipstick hole as you can -- it takes 18 3/4 inches of suction tube to the bottom. Set the suction pump lower than the Sea-Doo and pump as much oil as possible out of the engine. Pull the suction tube out of the engine, fully depress and hold the throttle lever and crank the engine, without starting it, for 10 seconds. Replace the tube in the dipstick hole and remove more oil from the engine. Repeat this process two or three times. Use a Sea-Doo oil filter cover separator and a Sea-Doo filter cover puller to remove the oil filter cover and an adjustable wrench to remove the oil filter screw. Unscrew the filter from the engine by hand, or use a strap wrench.
Inspect the oil filter cover O-ring and the oil filter screw O-ring visually and replace if necessary. Clean the oil filter inlet and outlet, if necessary. Moisten the tip of a finger with engine oil and spead a fine coat of oil to the filter's built-in gasket, the filter cover O-ring and the filter screw O-ring. Screw the filter into place and install the filter screw and cover. Torque the filter screw to 6.64 foot-pounds using a torque wrench. Add the quantity of oil specified in your Sea-Doo owner's manual to the oil tank, through the oil filler. Replace the oil filler cap and the dipstick. Depress the dipstick fully, remove it, wipe it with the clean cloth. Reinsert the dipstick and remove it once again. The oil level should be between the high and low marks on the dipstick. Replace the dipstick.
- Before you begin disconnect the negative cable of the boat’s battery before performing any maintenance work on the boat’s engine, using a 5/16-inch box end wrench. Lift the cable from the battery, move it outside of the battery box and close the lid of the battery box. After the work is complete, reconnect the negative battery cable.
- Before you begin your oil change, make sure your Sea-Doo is level, both side-to-side and fore-and-aft. Although the oil suction pump's tube goes deep in the engine, oil has a nasty way of using gravity to hide.
