Owner’s Manual
Trim Tab Operation
Head Sea — (Waves or current running directly against
the course of a boat)
Lower both tabs slightly by pressing
BOW DOWN on both sides. This brings bow down while
maintaining speed. This adjustment allows the hull of the
boat to absorb the impact of the waves, resulting in a
more efcient and smoother ride.
Following Sea —
(Waves or current running with the
course of a boat)
Make sure the tabs are fully retracted
by pressing BOW UP on both sides. This brings both
tabs to a fully retracted position decreasing lift in the
stern, allowing the bow to rise. If tabs are deployed, the
bow may dig.
Windy Chop — To raise the windward side of the boat
press B
OW UP o
n that side. If this is not sufcient, press
B
OW DOWN o
n the leeward side of the boat. Do not over
trim when attempting this. This allows the windward side
of the boat to rise and minimizes spray.
Shallow Water/Hole Shot — Lower both tabs completely
down by pressing B
OW DOWN o
n both sides. This
provides lift in the stern of the boat and keeps the bow
down. As you throttle up and speed increases, raise tabs
by pressing B
OW UP o
n both sides.
Uneven Load
—
If one side of the boat is higher than the
other while running, press B
OW DOWN o
n the switch on
that side. This lowers the tab on the listing side (low side)
to bring the boat level.
Porpoising —
(When the bow of the boat leaps clear out
of the water after striking a wave.)
To stop porpoising,
press BOW DOWN on both sides of the switch. The tabs
need only to be deployed slightly to correct this adverse
situation.
• While the boat is underway, do not move one tab up or down signicantly
as this may cause listing.
•
W
hile at higher speeds, do not over trim. This causes the bow to lower
quickly, resulting in a reduction of speed and may cause the boat to veer.
•
W
hen running in a following sea the tabs should be fully retracted. This
allows for optimal performance.
•
W
hile operating trim tabs, use caution. Improper use of trim tabs may
cause accidents and/or injury.
