Trim Tabs
TRIM TAB SWITCH
PORT ROCKER
STBD. ROCKER
If installed, trim tabs are located on the lower hull
of the transom. Water is defl ected and redirected
as the trim tabs are raised and lowered from the
starboard helm located trim tab switch. This
change in water fl ow creates upper pressure under
the tabs, and raises the stern. When the stern rises,
the bow is lowered. Lowering the port tab will cause the port stern
to rise, making the starboard bow lower. Lowering the starboard tab
will cause the starboard stern to rise, making the port bow lower. The
pressure originates from a pump and valve system at the aft bilge.
Using trim tabs in
conjunction with the power
trim will compensate for
uneven weight distribution,
listing, water conditions,
and other factors that
cause ineffi cient operation.
Remember, that trim tabs
are trimming the hull while
power trim is trimming the
engine drive.
