How to Check an '01 Sea-Doo GTX for Oil

Checking the oil on a 2001 Sea-Doo GTX may seem an arduous process, requiring that you remove things that are in the way just to see if the oil level is in order. If the oil isn't in order, though, both the jet pump and the engine will bring your boating day to a spectacular end. Either the engine will internally hemorrhage and strand you, or the jet pump will sling parts indiscriminately across the seascape, disturbing wildlife and other boaters. This possibility offers sufficient incentive to check the oil.

      Pull the variable trim system connecting rod from the engine compartment. Disconnect the two nuts holding the steering cable in place using a 1/2-inch open-end wrench. Remove the cable.

      Tap the cover of the oil reservoir with a hammer to loosen it. Remove the cover. The oil should reach the threads at the bottom of the hole into which the cover screws. If it does not, add Sea Doo Synthetic Oil, Part No. 293 600 011 until it reaches the threads.
