Notes
• 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.
The trim tab should be replaced
when it has eroded 2/3 of it's
regular size.
