Personal Watercraft Maintenance Tips – Maximize Fun
There is nothing more frustrating and disappointing than gearing up for a fun day of playing on the water, only to be confronted with an inoperable personal watercraft (PWC). Perhaps even worse, to get stuck out on the open water. But with some attention to simple maintenance, you will have many fewer problems and a lot more fun.
Before Every Personal Watercraft Ride
Prior to every ride, you need to give your PWC’s engine a once over. Check the engine’s oil level and, if needed, slowly add additional oil. However, be careful not to overfill. Also, check hoses, clamps, and electrical connections to make sure none of these connections are loose.
Post Ride
While the same considerations are necessary for riding in both saltwater and freshwater, more rigorous post-ride care is needed after saltwater usage given saltwater’s highly corrosive effects.
Engine Flushing
Personal watercraft, with very few exceptions, use the water they run in for cooling. Therefore, the water 
the craft is operated in circulates throughout the PWC’s cooling system, in addition to the engine’s exposure to water due to simply operating in the water. Therefore, flushing the engine is needed after every single saltwater ride due to the corrosive effects of salt. We recommend using flushing products such as Salt & Corrosion Terminator. Additionally, engine flushing should be performed regularly for freshwater riders to avoid algae, sediment, and other build-up.

Engine Rinsing
Gently spray down your engine with a garden hose after every saltwater ride to remove the corrosive saltwater. Additionally, freshwater riders should regularly rinse their engines to prevent grime, sediment, and other build-up from accumulating.
Rinse the PWC’s Body & Trailer
Just as the engine needs to be rinsed, so does the PWC’s body. This rinsing needs to occur after every saltwater ride to battle the corrosive effects of saltwater and regularly for freshwater riders. Also, don’t forget to rinse your trailer. After rinsing the body and the engine, pop up the seat and let the engine, body, and trailer dry thoroughly.
Anti-Corrosion Spray
After your PWC’s body and engine have thoroughly dried, spray the engine and other appropriate parts with an anti-corrosion spray. Also, don’t forget your trailer.

Maintain Your Personal Watercraft Battery
For the most part, battery maintenance is simply fully charging your battery between rides. Fully charging your battery not only ensures the operation of your PWC, but also helps your battery retain its ability to hold a charge. Battery neglect can lead to the formation of sulfate crystals on the battery’s plates which will over time decrease your battery’s ability to perform.
Finally, clean your battery terminals regularly to avoid build-up of corrosion, dirt, or moisture on the terminals. Don’t allow corrosion, dirt, or moisture to build up on the terminals. We recommend Yamaha Battery Cleaner & Protector (update) for added protection year-round.

Seasonal or Occasional Tasks
Wax & Protect
Wash your PWC at the start of the season, then apply a good coat of wax. A quality wax will protect your PWC from the 
damaging effects of UV rays. Additionally, we recommend using a good vinyl protectant to protect your seats.

Lubricate
Add grease to all seals and bearing fittings, and lubricate the parts.

Winterize
When the season is over and it’s time to store your PWC, drain any water from the engine, flush the engine, clean the craft thoroughly, lubricate metal hinges, handles, bearings, and fittings, fill with fuel and add fuel stabilizer, put on the cover and start dreaming of next season.
