4. INSTALLATION TRANSOM It is your responsibility to choose a boat suitable for the engine (9.9 horsepower BFlOO, 7.5 horsepower BF75). M Do not exceed the boat manufacturer’s power recommendation. Damage and injury may result. 1. Installation Position Install at the stern at the center line of the boat. 2. Installation Height Make sure that the transom height is correct for the motor. Incorrect installation height will reduce performance.
4. Motor Angle (In cruising) Adjust the motor so the axis of the propeller is parallel with the water surface. CAUSES INCORRECT BOAT TO “SQUAT” CAUSES INCORRECT BOAT TO “PLOW’ GIVES CORRECT MAXIMUM PERFORMANCE 5. Motor Angle Adjustment If the propeller axis is not parallel with the water surface, adjust by changing the adjusting rod position. There are four adjusting stages. USTING 1. Push in (A) the adjusting rod, twist upwards (B) and pull out to remove. 2.
5. PRE-OPERATION CHECK 1. Check the engine’oil level. CAUTION: Engine oil is a major factor affecting engine performance and service life. Non-detergent and low quality oils are not recommended. l Running the engine with insufficient oil can cause serious engine damage. l Use Honda 4-stroke oil, or an equivalent high detergent, premium quality motor oil certified t0 meet or exceed U.S. automobile manufacturer’s requirements for Service Classification SE or SF.
2. Check the fuel level Check the fuel gauge and refill the tank if the fuel level is low. NOTE: Open the vent knob before removing the fuel filler cap. When the vent knob is firmly closed, the cap will be difficult to remove. Use any regular grade automotive gasoline (unleaded gasoline is preferred) with a pump octane rating of 86 or higher. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank.
3. Check the following l l l l 12 items. Check the propeller, the shear pin, and the cotter pin to be sure they are secure and undamaged.
