Trim tabs are used to add lift to the boat’s stern, thereby
changing the boat’s attitude (see  Figure S1). This lift
can help the boat  get on plane faster and  remain on
plane at slower speeds than if no tabs were used. Used
independently, tabs can also correct listing conditions
caused by crosswinds, unbalanced loading and quar-
tering seas. Trimming  your inboard boat properly  in-

switch. If listing to port, press

Remember that most  boats react very  slowly to trim
tabs. Often boat owners do not give  trim tabs time to
work. Press the trim tab switches for only one second
at a time and then allow some time for the boat to re-
act. If the boat is still listing after a minute or two, press
the trim tab switch again for a one second interval. The
labels on the trim tab switches indicate what you want
your boat to do, not what you want the tabs to do.
When you are sitting dead in  the water, your trim tab
switches are in the BOW UP position. Accelerate until
you get onto plane.At this point your boat will be plow-
ing through the water with the bow down too far. Trim
the tabs down slightly until  the bow comes up. If you
trim the tabs down  too far, the propeller will cavitate.
Your boat is trimmed correctly when  it is just short of
propeller cavitation, under ideal running conditions.
It is a good idea to take your boat out onto open water
shortly after  you get  it and experiment  with the  trim
tabs.After you get your boat onto plane, set the tabs in
various positions and note how your boat reacts. This
will give you a feel for how the trim tabs work.
Trim your boat to compensate for seas, winds, or un-
even loads.
It is possible to extend the cylinder life expectancy on
your trim tabs. To do this, keep the cylinders retracted
while at dockside. Press  both trim tab controls down
until tabs reach their full up position.
