Trim Tabs
The trim tabs are a separate system in
themselves and are not to be used in lieu of the
drive unit power trim system. Water is deflected
and redirected as the trim tabs are raised and
lowered. This change in the water flow creates
upward pressure under the tabs and raises the
stern. When the stern raises, the bow is lowered.
Likewise, lowering the port tab will cause the port
stern to raise, making the starboard bow lower.
