Winterizing your Polaris jet ski is essential to ensure it remains in good condition during the off-season. Proper winterization protects your jet ski from cold weather, prevents damage, and extends its lifespan. This guide provides a step-by-step approach to winterizing your Polaris jet ski, making it simple to follow.
Preparation
Before starting the winterization process, gather all the necessary tools and materials. You will need:
- Jet ski manual
- Freshwater hose
- Fuel stabilizer
- Fogging oil
- Antifreeze
- Battery charger
- Cleaning supplies
- Storage cover
Step 1: Clean Your Jet Ski
Begin by thoroughly cleaning your jet ski. This removes salt, grime, and debris that can cause damage during storage. Follow these steps:
- Rinse with fresh water: Use a freshwater hose to rinse off saltwater and dirt. Pay special attention to the hull, intake grate, and pump area.
- Wash with soap: Use marine-grade soap to clean the exterior. Scrub gently to avoid scratching the surface.
- Dry completely: Ensure the jet ski is dry before proceeding. Use a clean towel to remove excess water.
Step 2: Stabilize the Fuel System
Fuel can deteriorate over time, causing engine problems. Stabilizing the fuel prevents this. Here’s how:
- Add fuel stabilizer: Pour the recommended amount of fuel stabilizer into the gas tank.
- Run the engine: Start the jet ski and let it run for about 10 minutes. This allows the stabilizer to circulate through the fuel system.
Step 3: Flush the Cooling System
Flushing the cooling system removes salt and debris, preventing corrosion. Follow these steps:
- Connect a hose: Attach a freshwater hose to the flush port.
- Run the engine: Start the jet ski and let it idle. Turn on the water and let it flow through the cooling system for a few minutes.
- Turn off the water and engine: Shut off the water supply first, then turn off the engine to avoid water intrusion.
Step 4: Fog the Engine
Fogging the engine protects internal components from corrosion. Here’s how to do it:
- Remove the air filter: Locate and remove the air filter to access the carburetor or throttle body.
- Spray fogging oil: Spray fogging oil into the carburetor or throttle body while the engine is running. This coats internal parts with a protective layer.
- Shut off the engine: Turn off the engine after spraying for a few seconds.
Step 5: Drain the Water from the Engine
Remove any remaining water from the engine to prevent freezing damage. Follow these steps:
- Tilt the jet ski: Raise the front of the jet ski to allow water to drain from the exhaust system.
- Crank the engine: Briefly crank the engine to expel any residual water. Do not run it for more than a few seconds.
Step 6: Add Antifreeze
Adding antifreeze protects the cooling system from freezing. Here’s how:
- Mix antifreeze: Dilute marine antifreeze according to the manufacturer’s instructions.
- Pour antifreeze: Pour the antifreeze into the cooling system via the flush port or cooling lines.
- Ensure circulation: Run the engine briefly to circulate the antifreeze through the system.
Step 7: Remove and Store the Battery
Proper battery storage extends its lifespan. Follow these steps:
- Disconnect the battery: Remove the negative (-) cable first, then the positive (+) cable.
- Clean terminals: Clean the battery terminals with a mixture of baking soda and water.
- Store in a cool, dry place: Store the battery in a cool, dry place, preferably on a trickle charger to maintain charge.
Step 8: Protect the Exterior
Protecting the exterior from the elements is crucial. Here’s how:
- Apply wax: Apply a coat of marine wax to the hull to protect it from moisture and UV damage.
- Cover the jet ski: Use a high-quality storage cover to protect your jet ski from dust and debris.
Step 9: Store in a Dry Location
Choose a dry, sheltered location for storage. If possible, store your jet ski indoors to protect it from the elements. Ensure the storage area is well-ventilated to prevent mold and mildew.
Step 10: Periodic Maintenance
During the storage period, perform periodic maintenance checks:
- Inspect for damage: Check for any signs of damage or wear.
- Charge the battery: Ensure the battery remains charged throughout the storage period.
- Ventilate: Occasionally uncover the jet ski to allow air circulation and prevent moisture buildup.
