TRIM TAB DASH SWITCH
PORT ROCKER
STBD. ROCKER
Using trim tabs will compensate for uneven weight
distribution, listing, water conditions, wind velocity and
other factors that cause inef
fi
cient operation.
TRIM TAB
TRIM TABS
Trim tabs are installed on the
lower outside transom area.
Water is de
fl
ected and redirected
as the trim tabs are raised and
lowered from the dash switches.
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.
Obtaining A Trimmed Position
Your boat reaches a planing position at a designated
speed. This speed is determined by bottom design, weight
distribution, water conditions, and on board equipment.
As the throttle is advanced the stern squats and the bow
rises initially. The trim tabs allow your boat to plane at a
slower speed than natural conditions allow.
In short bursts both trim tab rocker switches are pushed
simultaneously in the “bow down” position which causes
the trim tabs to move down. As the boat breaks over the
bow high attitude the boat speed accelerates and visibility
increases.
If the boat is over trimmed, it will plow the bow and
the boat will lose maneuverability. If this occurs, simply
short burst the “bow up” trim tab rocker switches
simultaneously.
In the “learning curve” process, press the tab switches
in half second bursts. You will notice a slight delay from
the time the switches are pushed until the boat reacts
depending on vessel speed. You will know after awhile the
optimum planing angle and speed.
When running in heavy seas press the “bow down” position
which will assist the vessel to cut through the waves. This
will produce a drier and more comfortable ride.
