SINGLE ACTUATOR SYSTEMS (1 ACTUATOR PER SIDE)
(The actuator with the red sensor wire installs on the port side of the boat,
and the actuator with the green sensor wire on the starboard side of the boat.)
1. Each trim tab is installed as an extension of the hull. To achieve this,
position the upper mount of each actuator with the trim tab on the same plane
as the hull bottom. Support the trim tab assembly from below in the fully
retracted position. Attach an actuator to the trim plane using the supplied
5/16-18 x 1 1/4" hex head machine screws. Tip back the upper mount such that
the wires and the hydraulic ports face away from the transom. Position the
assembly template over the end of the upper mount as shown in Figure 3.
The radius on the top of the uprights should nest fully into the assembly
template. This will temporarily locate the position of the upper mount.
Mark the position of the assembly template by tracing around the perimeter of
the template.
Figure 3
2. Remove the actuators from the trim tab and set aside.
3. Hold the assembly template placed in the marked position, then
mark the outline of the four mounting holes, the pipe nipple holes
and the sensor cable hole.
4. Remove the assembly template. When completed, you should
have an outline of the actuator upper mount as shown in Figure 4.
5. Drill the marked 8mm (5/16") mounting holes for each
actuator. Drill the 19mm (3/4") hole in the transom for the sensor
wire. And drill the 12mm (1/2") holes for the pipe nipples.
IMPORTANT: The hole for the sensor wire must be
accurate — match the template exactly so that the wire
goes through the transom easily. Be careful not to crush
or pinch the wire while mounting the actuator.

6. Once all the holes are drilled, mount the actuators to the trim
tab using the supplied 5/16-18 x 1 1/4" hex head machine screws.
DO NOT TIGHTEN.
