  • Page 50: Installation

    EMU00175 INSTALLATION CAUTION: Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat or accessories such as transom ladders/depth finder transducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operated continuously in the presence of airborne water spray.

  • Page 51: Breaking In (Running In) Engine

    EMU00224 BREAKING IN (RUNNING IN) ENGINE Your new engine requires a period of break- in (running-in) to allow mating surfaces of moving parts to wear-in evenly. Correct break-in (running-in) will help ensure proper performance and longer engine life. CAUTION: Failure to follow the break-in (running-in) procedure may result in reduced engine life or even severe engine damage.

  • Page 52: Pre-Operation Checks

    EMU00204 PRE-OPERATION CHECKS WARNING If any item in the pre-operation check is not working properly, have it inspected and repaired before operating the out- board motor. Otherwise, an accident could occur. CAUTION: Do not start the engine out of water. Overheating and serious engine damage can occur.

  • Page 53: Checking The Engine Oil Level

    EMU00261 SHIFTING WARNING Before shifting, make sure there are no swimmers or obstacles in the water near you. CAUTION: To change the shifting position from for- ward to reverse or vice-versa, close the throttle first so that the engine idles (or runs at low speeds).

  • Page 59: Stopping Engine

    EMU00273 STOPPING ENGINE Let it cool off for a few minutes at idle or low speed first. Stopping the engine immediately after operating at high speed is not recom- mended. EMU01199¯ 1) Turn the main switch to “OFF”. 2) If there is a fuel joint or a fuel cock on the boat, disconnect the fuel line or close the fuel cock after stopping the engine.

  • Page 60: Trimming Outboard Motor

    EMU01412 TRIMMING OUTBOARD MOTOR The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel economy while reducing strain on the engine. The cor- rect trim angle depends upon the combina- tion of boat, engine, and propeller.

  • Page 61: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU01657 Power Trim/Tilt Model WARNING Be sure all people are clear of the out- board motor when adjusting the trim/ tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. Use caution when trying a trim posi- tion for the first time.
  • Page 62 EMU01558 Bow Up When the boat is on plane, a bow-up atti- tude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. When trimmed out, the boat may have more tendency to steer to one side or the other.

  • Page 63: Tilting Up/Down

    EMU01670 TILTING UP/DOWN If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the pro- peller and casing from damage by collision with obstructions, and also to reduce salt corrosion.

  • Page 64: Procedure For Tilting Up

    EMU01575 PROCEDURE FOR TILTING UP Power trim and tilt models 1) Disconnect the fuel line or close the fuel cock. 2) Push the power trim and tilt switch “UP” until the outboard has tilted up com- pletely. 3) Turn the tilt support lever toward you to support the engine.

  • Page 65: Procedure For Tilting Down

    EMU01576¯ 4) Once the engine is supported with the tilt support lever, push the power trim and tilt switch “DN” (down) to retract the trim rods. CAUTION: Be sure to retract the trim rods com- pletely during mooring. This protects the rods from marine growths and corrosion which could damage the power trim and tilt mechanism.
