Notes
 Change trim tab angle a little for each
test run and repeat the process several
times until the best position is found.
 The trim tab also acts as an anode to
prevent electrolytic corrosion. Therefore
do not paint or grease this part.
 After adjustment securely tighten the
trim tab fixing bolt.
 Check for looseness of the bolt and the
trim tab at regular intervals.
Due to corrosion, the trim tab will wear
down over time.
 Inappropriate adjustment of trim tab
could cause steering difficulty. After
installing or readjusting trim tab, check
if steering load is even.
 Tighten trim tab bolt to specified torque.
 Be sure that outboard motor is secured
to transom or service stand, or acciden-
tal drop or fall of outboard motor could
lead to severe personal injury.
 Be sure to lock outboard motor if it is
tilted up, or accidental fall of outboard
motor could lead to severe personal
injury.
 Do not go under outboard motor tilted
up and locked, or accidental fall of out-
board motor could lead to severe per-
sonal injury.
Steering load can be adjusted by turning
the steering adjust bolt on the Swivel
Bracket.
Turn clockwise to increase load
Turn counter-clockwise to decrease the
load
