Section 4
Proper Boat Trim
All boats “break over” or get on plane at a particular
speed. This speed is determined by load distribution,
water conditions, and other factors. Trim tabs allow
your boat to plane at speeds below its natural planing
speed. By pressing the
BOW DOWN
buttons, your
trim tabs move down. This will raise your stern and
lower your bow, getting the boat on plane sooner.
When learning to use trim tabs, begin by pressing the
tab buttons in ½ second bursts for gradual trimming. A
momentary delay occurs from the time you press the
tab buttons to the time the boat reacts. This delay is
normal and varies with boat speed. Be careful not to
over-trim the boat. An over-trimmed boat will “plow” or
“bow-steer”. If you over-trim the boat, push both
BOW
UP
buttons to raise the bow.
Rough Water
When running in chop or heavy seas, press both
BOW
DOWN
buttons to lower the bow elevation. This will
bring the “V” of the hull in more contact with the waves
and reduce the pounding effect.
!
WARNING
The boat’s attitude and steering effort can react
very quickly to changes in trim tab position.
Adjust trim tab deployment in small increments
to avoid loss of boat control.
!
WARNING
Do not over-trim, particularly at high speeds, as
the bow will dig in and wave action might cause
the boat to veer. While underway, do not move
one trim tab significantly farther down than the
other, as undesirable listing will occur.
