Sea-Doo Personal Watercraft Impellers and Components

Enjoying a day on the lake or at the beach with your Sea-Doo watercraft jet-ski offers thrills that many experiences cant match. Keeping your Sea-Doo well-maintained by replacing worn parts will help maximize its performance and extend the lifespan of your recreational craft. Regularly checking the Sea-Doo personal watercraft impellers and components for wear and tear is a vital part of maintaining your Sea-Doo for readiness.

How do you install a new Sea-Doo impeller?

When it comes time to install personal watercraft impellers and components, keep in mind that the impeller is similar in function to a propeller in that the spinning of the impeller is what moves your Sea-Doo through the water. Rather than having a series of blades that cut through the water like a propeller, an impeller uses centrifugal force, channeling water in a circular pattern through a hole in the center of the impeller. This action moves the Sea-Doo forward and is critical to the function of your Sea-Doo personal watercraft.

To replace the impeller on your Sea-Doo watercraft, you must remove the existing impeller. This is held in place by a Loctite seal using a product known as Blue Loctite. This product is specifically used to seal the Sea-Doo impeller into place within the threaded housing, creating a barrier that reduces vibration while locking the impeller into place.

To break the bond of the Blue Loctite and remove the existing impeller, it is recommended that you use heat to loosen the bonds of the Blue Loctite. If available, a small propane torch can be used, applying heat to the center portion of the impeller for no more than five seconds to loosen or break the seals.

How can you tell if water has breached the seals?

The engine housings and seals of your Sea-Doo play a critical role in keeping water from entering the engine and other components while the Sea-Doo is in use. Because your Sea-Doo is exposed to water constantly when in use and because the elements - from salt to dirt to plant life - can cause damage or corrosion to different parts of the engine, making sure that the seals are intact and checking for any signs of breach are important maintenance procedures.

A simple check to see if any water has entered the oil pump system includes visually inspecting the oil when draining the oil pump. If the oil has a discolored appearance with a cloudy or milky look, it is likely that you have water in the system. Discard the drained oil, check and replace any worn seals, then refill the oil pump with the correct pump oil for your Sea-Doo.
