Yamaha 15Hp Outboard Instructions

You don't need to be an old salt to operate a 15-horsepower Yamaha outboard. The safety procedures, like checking for fuel leaks -- a leaky fuel line can lead to a fire, or worse, an explosion -- are straightforward. The engine is equipped with a manual choke and an electric starter that operates on the push of a button rather than the turn of a key. It weighs in at just over 100 pounds, making it easier to mount and manage than its heavier cousins.

Instructions

    • 1

      Ensure you have sufficient fuel. Check the fuel lines and connections for leaks. Sniff for fumes. Ensure the tank is secured in position and the fuel line is untwisted and in order.

    • 2

      Check the operation of the throttle, shifter and steering -- the controls should move smoothly. Ensure the engine is mounted securely. Inspect the propeller for signs of damage.

    • 3

      Move the outboard so it is upright. Remove the cover from the engine. Pull the dipstick from its tube and wipe it clean. Reinsert the dipstick and remove it once again, observing the oil clinging to it. If the oil level is acceptable, the oil will lie between the upper and lower marks on the dipstick's surface. Add oil if necessary.

      Loosen the vent screw in the gas tank. Move the gear shift lever to the center "neutral" position. Connect the engine stop switch lanyard to your clothing or person. Place the lock plate on the lanyard into the engine stop switch. Twist the throttle grip to the "Start" position. Pull the choke knob out all the way.

    • 5

      Push the starter button on the left side of the motor. When the engine starts, release the starter button and twist the throttle grip clockwise to the fully closed idle position. Slowly push the choke knob back in. Allow the motor to warm to operating condition and begin boating.
