68J-9-14-3 2/28/02 11:13 AM Page 18 E 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 correct trim angle depends upon the combination of boat, engine, and propeller. Correct trim is also affected by variables such as the load in the boat, sea conditions, and running speed.
68J-9-14-3 2/28/02 11:13 AM Page 19 E ADJUSTING TRIM ANGLE EMU01401 Power Trim/Tilt Model w 8 Be sure all people are clear of the outboard motor when adjusting the trim/tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. 8 Use caution when trying a trim position for the first time. Increase speed gradually and watch for any signs of instability or control problems.
68J-9-14-3 2/28/02 11:13 AM Page 20 E EMU01558 Bow Up When the boat is on plane, a bow-up attitude 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. Compensate for this as you steer. The trim tab can also be adjusted to help offset this effect. q 105011 w Too much trim-out puts the bow of the boat too high in the water.
