FUEL AND OIL

Gasoline

WARNING

•Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions.

•Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

•Do not use leaded gasoline.

Leaded gasoline can seriously damage the engine.

•Avoid getting water and con- taminants in the fuel tank. Contaminated fuel can cause poor performance and engine damage. Use only fresh gasoline that has been stored in clean containers.

1)Before refueling, turn off the engines. Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition.

2)Refuel the boat in a well-ventilated area. If the boat is in the water, be sure it is securely moored to the fueling dock. All passengers must be out of the boat during refueling.

3)Remove the fuel tank filler cap, and then slowly add fuel to the fuel tank. Stop filling when the fuel just becomes visible in the bottom of the filler tube. Do not “top off” the tank, because gasoline could spill out.

4)Wipe up any spilled fuel immedi- ately.

6)Install the fuel tank filler cap. Make sure that the fuel tank filler cap is securely closed.

Gasohol

Recommended fuel:

Regular unleaded gasoline with a minimum octane rating of 86 (Pump octane number) = (R + M)/2 90 (Research octane number)

Fuel tank capacity: 50 US gal (189 L)

There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Gasohol containing methanol is not recommended by Yamaha because it can cause fuel system damage or engine performance problems.

Ring Free Fuel Additive

As fuel mixture burns in your engine's combustion chambers, carbon deposits are left behind. Over time, these deposits can reduce performance and even cause engine damage. Marine engines tend to run at lower operating temperatures than other engines, making them more likely to accumulate these harmful deposits. Ring Free Fuel
