Tips for Watercraft Maintenance: Complete Guide

Maintaining a jet ski is key to ensuring its proper functioning, extending its lifespan, and avoiding costly mechanical issues. If you own a jet ski or are thinking of getting one, this guide will provide you with the best tips to keep it in perfect condition.

1. Cleaning After Each Use

Saltwater is highly corrosive, so it's essential to clean the jet ski after every use.

• Rinse with fresh water: Use a hose to remove salt and sand residues.
• Dry the metal parts thoroughly: This will prevent rust formation.
• Use anti-corrosion products: Spray an anti-corrosion product on the metal parts for protection.

2. Regular Visual Inspection

Checking your jet ski's condition before and after each ride is a recommended practice.

• Inspect the hull: Look for cracks, scratches, or any damage that could affect its performance.
• Check the water intakes: Ensure there are no obstructions from algae or debris.
• Verify the exhaust system: Any leaks could be dangerous and affect engine performance.

3. Oil Change

The engine oil should be changed regularly to ensure proper lubrication.

• Frequency: It is recommended to change the oil every 50 hours of use or at the end of each season.
• Oil filter: Don't forget to also replace the oil filter for complete maintenance.

4. Take Care of the Cooling System

Jet skis use a cooling system that can get clogged with salt, sand, or algae.

• Flush the cooling system: Use a flush kit to clean the system after each use in saltwater.

5. Battery Maintenance

The battery is a vital component that requires special care.

• Disconnect the battery: If you won't be using the jet ski for an extended period.
• Charge the battery regularly: If you don't use the jet ski often, use a battery charger to keep it in good condition.

6. Propulsion System Maintenance

The impeller and propulsion pump should be in good condition for optimal performance.

• Check the impeller: Ensure it's not damaged or clogged with algae or debris.
• Inspect the pump: Any wear or damage can reduce the jet ski's efficiency.

7. Proper Storage

If you won't be using the jet ski for an extended period, it's important to store it properly.

• Choose a dry and covered place: Protect the jet ski from the elements.
• Use a cover: Cover the jet ski with a breathable cover to prevent dust and moisture buildup.
• Elevate it off the ground: If possible, place the jet ski on a stand to avoid direct contact with the ground.

8. Professional Check-Up

Even if you do good maintenance on your own, it's advisable to take the jet ski to a specialized workshop for a professional inspection.

• Frequency: At least once a year, especially before the summer season.
• Comprehensive diagnostics: Professionals can detect issues that aren't visible to the naked eye.

9. Spark Plug Replacement

The spark plugs should be in good condition for efficient ignition.

• Frequency: Replace the spark plugs every 25-50 hours of use.
• Inspection: If you experience starting difficulties, check the spark plugs and replace them if worn out.

10. Keep the Fuel Tank Clean

Fuel can deteriorate if stored for a long time.

• Use a fuel stabilizer: If you won't be using the jet ski for several months, add a stabilizer to the fuel to prevent degradation.
• Avoid leaving the tank half-empty: Air in the tank can cause condensation and create moisture, leading to fuel system problems.

Additional Tips:

• Carry a tool kit onboard: Include basic tools such as wrenches, screwdrivers, and a flashlight.
• Documentation: Always carry the proper documentation for your jet ski.
• Insurance: Get proper insurance that covers both personal and third-party damages.
