Operations
Trimming outboard motor
The trim angle of the outboard motor helps determine the position of the bow of the boat in the
water. Correct trim angle will help improve performance and fuel economy while reducing strain
on the engine. Correct trim angle depends upon the combination of boat, engine, and propeller.
Correct trim is also affected by variables such as the lead in the boat, sea conditions, and running
speed.
WARNING
Excessive trim for the operating conditions (either trim up or trim down) can cause boat
instability and can make steering the boat more difficult. This increases the possibility of an
accident. If the boat begins to feel unstable or is hard to steer, slow down and/or readjust the trim
angle.
Adjusting trim angle
There are 4 or 5 holes provided in the clamp bracket to adjust the outboard motor trim angle.
1. Stop the engine.
2. Remove the trim rod from the clamp bracket while slightly tilting the outboard motor up.
3. Reposition the rod in the desired hole.
To raise the bow (“trim-out”), move the rod away from the transom.
To lower the bow (“trim-in’), move the rod toward the transom.
Make test runs with the trim set to different angles to find the position that works best for your
boat and operating conditions.
WARNING
Stop the engine before adjusting the trim angle.
Use care to avoid being pinched when removing or installing the rod.
Use caution when trying a trim position for the first time. Increase speed gradually and watch for
any signs of instability or control problems. Improper trim angle can cause loss of control.
The outboard motor trim angle can be changed approximately 4 degrees by shifting the trim rod
one hole.
Adjusting boat trim
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. With the bow up, the
boat may have a greater 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. When the bow of the boat is down, it is
easier to accelerate from a standing start onto plane.
