Jet Ski Maintenance Tasks You Should Never Skip

Owning a jet ski brings unparalleled excitement, but that fun relies on consistent care. Proper jet ski maintenance can extend its life and promise safe performance and reliability every time you hit the water. Neglecting key tasks will just lead to costly repairs and unexpected breakdowns, ultimately cutting your season short—something nobody wants.

We’re reviewing a handful of jet ski maintenance tasks you should never skip. You will protect your investment and maximize your time on the water with these simple checks in your routine.

Keep the Engine Clean

After each ride, especially in saltwater, you must flush the engine and exhaust system with fresh water. This simple step prevents salt, sand, and algae from causing corrosion and blockages inside the engine’s cooling passages. Most jet skis have a built-in hose connection point, which make this process pretty straightforward.

Check Oil Levels

Just like a car, your jet ski engine needs the right amount of oil to run smoothly. Before you ever hit the water at the start of the day, check the oil level using the dipstick and top it off if necessary. Refer to your owner’s manual for the correct oil type and fill level to avoid engine damage.

Inspect the Battery

A dead battery will end your day before it starts. You should regularly inspect your battery terminals for any signs of corrosion. Clean them with a wire brush if you spot buildup. Make sure the connections are tight and consider using a trickle charger during the off-season to maintain the battery’s health.

Examine the Spark Plugs

Spark plugs are critical for engine ignition and performance. You should inspect them periodically for wear and fouling. If the electrodes appear worn or covered in residue, take this as a sign to replace them. Unfortunately, faulty spark plugs lead to hard starts, poor acceleration, and increased fuel consumption.

Lubricate Moving Parts

Many moving PWC components demand ample lubrication to prevent them from seizing up. Apply marine-grade, water-resistant grease to parts, such as:

• Steering cables
• Throttle cables
• Reverse gate pivots

Test the Bilge Pump

The bilge pump is a crucial safety feature that removes water from the hull. You’ll want to test it to confirm it works correctly before each outing on the water. A malfunctioning bilge pump could lead to a swamped engine compartment if you take on too much water.

Inspect the Impeller

The impeller, housed within the jet pump, is what propels your watercraft. You should check it regularly for damage from debris like rocks or rope. A bent or chipped impeller will cause vibration and reduce the jet ski’s performance. If you find significant damage, you may need to source jet ski replacement parts to restore proper function.

Following a consistent maintenance schedule is the best way to keep your jet ski in peak condition. These routine tasks prevent major issues, keep you safe on the water, and extend your PWC’s lifespan.

By dedicating a small amount of time to care before or after each ride, it’ll always be ready for your next adventure. Let SBT help you get all the replacement parts you need any time a maintenance tasks hints at more extensive work.
