About PWC
A personal watercraft, also called a jet ski, moves by pulling water into a jet pump and pushing it out the back; the engine spins an impeller inside the pump instead of turning a propeller. Sand, salt, heat and hard throttle all wear the machine, so owners shop here for impellers and other pump parts, gasket sets and pistons, steering and starting parts, and the covers, grips and mats that make a machine easier to live with.
The sub-categories follow the machine. Engines, Impellers & Component covers the engine and the pump, Ignition & Starting Systems the ignition and starting parts, Intake & Fuel Systems the intake and fuel parts, and Exhaust the exhaust. Body Parts covers the hull and body. Accessories & Gear and Accessories hold add-ons, and Other Parts holds the remainder.
Almost every part is specific to the make, model and year, because pumps, hulls and engines differ between machines. Pick yours in the Ride Finder at the top of the page. Listings here name Sea-Doo, Yamaha, Kawasaki and Polaris machines, and sizes such as piston bore are given in millimeters, so match them to your engine. Brands include Atlantis, Vertex, Helix, Airhead, Solas and WSM. If you are unsure about fit, why a part did not fit and how to avoid it lists the checks.
FAQs on personal watercraft parts
How do I find the right part for my jet ski?
Start with the make, model and model year, and for engine parts the engine size. Hulls, pumps and engines change between years even on the same model name. Use the Ride Finder at the top of the page and confirm against your owner's manual or the numbers on the old part.
Which parts on a jet ski wear out first?
In the pump, the impeller and the wear ring take the abuse from sand and debris. In the engine, spark plugs and gaskets are routine, and pistons and rings wear with hours. Fuel filters and lines age with time. Your owner's manual lists the inspection intervals.
Should I flush a personal watercraft after riding in salt water?
Most makers recommend flushing the engine cooling system with fresh water after salt-water use, and rinsing the hull and metal parts, because salt speeds corrosion. The method varies by model, so follow the steps in your owner's manual.
Are parts for different jet ski brands interchangeable?
Mostly not. Sea-Doo, Yamaha, Kawasaki and Polaris use different pumps, engines and mounts, so parts are listed by make, model and years. Some aftermarket parts fit several models, and the listing says which. Check the exact make and model before you order.
How do I prepare a jet ski for storage?
Follow the storage steps in your owner's manual. They typically cover flushing the cooling system, treating the fuel, coating the engine internals with fogging oil, drying the hull and checking the battery. Skipping them can cause hard starts and corrosion later.
