WARNING

●Leaking fuel is a fire hazard. When trans- porting and storing the outboard motor, close the fuel cock to prevent fuel from leaking.

●Never get under the outboard motor while it is tilted, even when the tilt sup- port shaft is installed. Severe injury could occur if the outboard motor acci- dentally falls.

The outboard motor should be trailered and stored in the fully tilted-down position. If the outboard motor cannot be trailered in the fully tilted-down position, the outboard motor must be secured in the tilted-up position using a support device, such as the Yamaha Trailering Support.

Storing outboard motor

When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage. It is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to storage. However, you, the owner, with a minimum of tools, can perform the following pro- cedures.

Conditioning and stabilizing gasoline

When preparing to store a boat for extended periods (2 months or longer) it is best to completely remove all gasoline from the boat’s

fuel tank(s). If it is not possible to remove the gasoline, add one ounce of “Yamalube Fuel Stabilizer & Conditioner Plus” to each gallon of gasoline in a full tank of gasoline to provide fuel stability and corrosion protection.

TIP:

Do not fill the fuel tank(s) to the point of over- flowing. Approximately 7/8 full will allow enough space in the fuel tank to prevent gasoline purging from the fuel tank vent due to expansion with temperature changes.

Do not cap the fuel tank vent. Excessive pressure could damage the boat and motor’s fuel systems.

A partially filled fuel tank, less than 7/8 full but not completely empty, is not recommended. Air space above the gasoline allows air movement which can bring in water through condensation as the air temperature changes.

Condensation inside the fuel tank can cause corrosion problems and phase separation of gasoline containing ethanol.

Consult your Yamaha dealer concerning preventative measures that may work best for the gasoline and environmental conditions in your area.
