The trim limiter system has three set points that
once set, will limit the trim range and tilt range of
the drive unit. The factory settings of these limits
are based on a boat with a 13° transom angle. Trim
is limited on a 13° transom angle to +5° to -2° for
the DuoProp ® and +12° to -6° for the SX and tilt is
limited to 45° on both models. If necessary, any of
these limits may be changed to accommodate
other transom angles and/or swim platforms. In
order to properly set the trim limiter, 'zero' trim
must first be determined as in figure 2. We
provide two methods in determining zero trim.
Method 1 requires the installer to know the boat's
transom angle. Method 2 is used if the transom
angle cannot be easily determined.
METHOD 1 - DETERMINING TRIM/TILT
ZERO (TRANSOM ANGLE KNOWN)
NOTE: The transom angle can be determined
by holding a carpenter's square along
the flat portion of the boat's bottom
and bring in the square until the end
contacts the transom. Read the
measurement at the intersection of
the hull bottom and the transom.
Each ¼-inch of measurement = 1
degree of transom angle.
1. After determining the boats transom angle
move the drive to the zero trim position by
extending or retracting the drive until the trim/

tilt cylinders are at the proper measurement
for zero (0) as shown in table 1 on the next
page under the appropriate transom angle
column.
2. Once zero is established, "sight-in" the drive
and boats bottom as shown in figure 2 to
verify accuracy. If the anti-ventilation plate
and boats bottom do not appear parallel use
Method 2 to zero out the drive.
3. Using the measurements given in table 1
measure the trim cylinder extension to
position the drive at the proper angles as
required to setup the trim limiter.
METHOD 2 - DETERMINING TRIM/TILT
ZERO (TRANSOM ANGLE UNKNOWN)
1. Ensure the electrical system is properly
connected and restore electrical power to the
boat's electrical system.
2. IMPORTANT: Place the boat on a secure
cradle, trailer, or other approved boat holding
device. Adjust the drive unit so that the anti-
ventilation plate is parallel to the boat's
bottom, refer to figure 2. Use a straight edge
along the boat's bottom to aid in determining
these lines. On a few boats, there may be a
slight hook designed into the hull near the
transom, disregard this hook and use the keel
