Trim tab with anode
WARNING
EWM00840
An improperly adjusted trim tab could
cause difficult steering. Always test run
after the trim tab has been installed or re-
placed to be sure steering is correct. Be
sure you have tightened the bolt after ad-
justing the trim tab.
The trim tab should be adjusted so that the
steering control can be turned to either the
right or left by applying the same amount of
force.
If the boat tends to veer to the left (port side),
turn the trim tab rear end to the port side “A”
in the figure. If the boat tends to veer to the
right (starboard side), turn the trim tab end to
the starboard side “B” in the figure.
NOTICE
ECM00840
The trim tab also serves as an anode to
protect the engine from electrochemical
corrosion. Never paint the trim tab as it
will become ineffective as an anode.
