Preparing Your Jet Boat for Winter Storage

Before you begin, gather the necessary supplies:

Shop towels
Fuel stabilizer
Fogging oil
Engine flush
Water repellent spray
Plastic sheeting or a boat cover
A bucket
Funnel
Storage area with proper ventilation

1. Cleaning Your Jet Boat

Start by thoroughly cleaning your jet boat. Remove any dirt, debris, salt, and grime. A clean boat is less susceptible to corrosion. Pay close attention to the hull, jet pump, and engine compartment. Pressure washing is effective, but be sure to dry everything thoroughly afterward.

2. Removing and Storing the Battery

Disconnect the negative battery terminal first, then the positive. Store the battery in a cool, dry place to prevent freezing and damage. Consider using a battery tender to maintain a charge.

3. Draining Fluids

Engine Oil: Drain the engine oil according to your boat's manual. Replace with fresh oil before next season.
Fuel: Run the engine until it's almost out of fuel. Then add fuel stabilizer to prevent gumming and varnish buildup over the winter months.
Cooling System: Completely drain the cooling system. Consult your owner's manual for specific instructions. This is critical to prevent freeze damage.
Jet Pump: Flush the jet pump with fresh water to remove any salt or debris. Some jet pumps have drain plugs; others require a flushing process. Check your owner's manual.

4. Fogging the Engine

Fogging protects internal engine components from corrosion. Follow the instructions on your fogging oil can. This step is essential to prevent rust and seizing. It creates a protective film on internal parts.

5. Protecting the Interior

Clean and Dry: Thoroughly clean and dry the interior. Remove any moisture sources like wet towels or gear.
Ventilation: Leave some ventilation to prevent mold and mildew growth.
Cover: Cover the interior with plastic sheeting or a boat cover to protect it from dust and debris.

6. Protecting the Hull

Washing and Waxing: Wash and wax the hull to protect the gel coat from damage.
Covering: Cover the hull with a high-quality boat cover designed to protect from the elements.

7. Winter Storage Location

Store your boat in a dry, well-ventilated area. Avoid damp basements or sheds where condensation can occur. Ideally, store it out of direct sunlight.
