• Solution: If the boat is
moving fast and slightly bow
heavy, the boat can attain a
planing attitude that is below
the angle that the boat might
idle at. In this case, the
system thinks that the boat
is moving slow, so it retracts
the tabs. This situation can
be changed by resetting the
planing angle at a lower
angle (See page 25). Use a
higher speed and additional
tab deployment when
resetting the planing angle.
• Potential Cause 2: The operating
speed of the boat naturally drives
the hull below the FAV position.

moving fast and the FAV
position is set at a relatively
low speed, as the boat speed

increases, the bow angle
will naturally decrease.
The system will recognize
that the bow is low and
try to bring the tabs up to
compensate. Once the tabs
are full-up, the tabs no
longer have any effect on
the bow angle. The tabs
cannot raise the bow to
achieve the FAV position.
Use the engine trim to raise
the bow and the boat will
come back into the operating
range where the trim tabs are
effective.
