line over its greatest length to determine the
exact bottom or keel line. Once both lines are
determined to be parallel, zero out a universal
level protractor or resettable electronic level
along the boat's bottom or keel line. Recheck
the underside of the anti-ventilation plate line
with either level to ensure the reading is zero
or adjust the drive to zero as necessary.
SETTING NEW TRIM/TILT LIMITS
If this trim limiter unit is being used on a boat with
DuoProp
®
with a 13° transom equipped with a swim
platform you must do steps 1 and 2 then you can
skip ahead to step 6 and set the high tilt limit
without changing the trim limit settings. For all other
transom angles and/or for SX drives complete
every step in this procedure.
1.
Turn the GAGE SEL. switch on the limiter
box to the "0" position. All three lamps (TRIM
LOW, TRIM HIGH, TILT HIGH) on the trim
limiter box should be flashing. The trim gauge
needle will move to the upper segment of the
gauge and remain there until the setup

switch is moved from the "0" position.
2.
Setting Lower Trim Stop Limit: Adjust the
drive unit to the lower trim limit of -2° and
make appropriate measurements using a
inside caliper (if using Method 1) or a
universal level protractor or resettable
electronic level (if using Method 2) on the
underside of the anti-ventilation plate to
measure the angle. Push PB-A button on the
trim limiter box and hold for four seconds.
The GREEN TRIM LOW lamp should light up
then go out. When PB-A button is released
all three lamps should begin flashing again.
The lower trim limit is now set.
3.
Setting Upper Trim Stop Limit: Adjust the
drive unit to the upper trim limit of +5° for the
®
DuoProp
and +12° for the SX, take
appropriate measurements to verify trim
angle. Press PB-B button on the trim limiter
box for four seconds. The YELLOW TRIM
