  • Page 13: Pre-Operation Checks

    1. Engine oil level /iiGiq Engine oil is a major factor affecting engine performance and sevice life. Nondetergent and low quality oils are not recommended, because they have inadequate lubricating properties. Running the engine with insufficient oil can cause serious engine damage.
  • Page 14 2. Fuel level Fuel tank capacity: 12 8 (3.0 US gal, 2.6 Imp gal) EL GAUGE Check the fuel gauge and refill the tank to the SAFE FILL LEVEL mark if necessary. Gasoline is extremely flammable, and gasoline virpor can explode, causing serious injury or death.
  • Page 15 Fuel Recommendations Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is desi ned to operate on unleaded gasoline. Unleaded gasoline produces ewer engine and spark plug deposits and extends . exhaust system life. Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
  • Page 16 OXYGENATED FUELS Some conventional asolines are being blended with alcohol or an ether compound. T ese gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.
  • Page 17 3. Pre-operation check list: @The propeller and cotter pin for damage or looseness. @Check the stern bracket to be sure the motor is securely installed. @Check tiller handle operation. @Make sure you have the tool kit and spare parts with you (P. 31). @Check the condition of the fuel cap, fuel cap gasket, fuel hose, or fuel hose connectors.

  • Page 18: Starting The Engine

    5. STARTING THE ENGINE Fuel line connection Check the fuel tank related components and fuel tank positioning (refer step @ and @ on page 15 1. Due to the fuel pump capacity, do not place the fuel tank more than 6 feet away from the motor or lower than 3 feet below the outboard end fuel hose connector.
  • Page 19 Starting Exhaust contains poisonous carbon monoxide which can cause unconsciousness and may lead to death. Never run the outboard in a closed garage or confined area. The anti-ventilation plate must be lowered into the water and be at least 2 inches below the surface. Running the outboard motor out of the water will damage the water pump and overheat the engine.

  • Page 30 0 High altitude operation At high altitude, the standard carburetor air-fuel mixture will be exces- sively rich. Performance will decrease, and fuel consumption will increase. High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor and readjusting the pilot screw. If you always operate the outboard motor at altitudes higher than 6,000 feet above sea level, have your authorized Honda Outboard Motor dealer perform these carburetor modifications.
