Systems
Using trim tabs in conjunction with the power trim will
compensate for uneven weight distribution, listing, water
conditions, and other factors that cause inefficient
operation. Remember, that trim tabs are trimming the hull
while power trim is trimming the engine drive.

Typical Trim Tabs
Trim tabs may be installed on the hull lower transom
area. Water is deflected and redirected as the trim tabs
are raised and lowered through the dash switches. This
change in water flow 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 Postition
Your vessel will reach a planing position at a specific 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 overtrimed, it will plow the bow and the boat
will lose maneuverability. If this occurs, simply short burst
the “bow up” trim tab rocker switch 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. In a
following sea run the tabs in a fully retracted angle for
maximum outdrive response.
Sometimes you can watch the bow spray or stern wake
and the rooster tail (mound of water produced by stern
drives). In a bow up position the spray is far aft to the
hull, the wake is high and the rooster tail is high.
