Trim Tab Angle Adjustment
After installing the outboard motor on your boat, make
sure the weight of the left and right steering handle is
evenly distributed at the trim angle and engine speed that
you normally or frequently use. For this purpose, loosen
the bolt of the trim tab, adjust it with the angle of the trim
tab 1 , and tighten it to the specified torque.
Trim Tab Bolt:
6 N·m (5 lb·ft) [0.6 kgf·m]
Apply OBM grease to the trim tab bolt.
Specific Example
A If the weight of the steering handle is lighter on the left
side, or if it tends to turn towards the left side, turn the
trim tab in the direction of A as shown in the diagram.
B If the weight of the steering handle is lighter on the right
side, or if it tends to turn towards the right side, turn the
trim tab in the direction of B as shown in the diagram.
Move the trim tab a little bit at a time and determine
the best position by repeating the test several
times.
