How to Replace the Drive Shaft Seal on a 1994 Sea-Doo XP

The drive shaft on the 1994 Sea-Doo XP plays an important role in the propulsion system on the personal water craft. The drive shaft, which is connected to the engine, spins the water pump impeller. This action both distributes water throughout the engine to keep it from overheating and helps propel the craft. Changing the water pump and impeller is a regular part of maintenance for the Sea-Doo. The drive shaft seal is a seal that is supposed to prevent salt water from entering the inside of the drive shaft system. It should be replaced to prevent engine damage.
