INSTRUCTIONS
BEFORE BEGINNING INSTALLATION:
READ INSTRUCTIONS COMPLETELY
MAKE SURE BATTERY POWER IS DISCONNECTED
TEST SYSTEM BEFORE PUTTING THE BOAT BACK IN THE WATER
IMPORTANT - SPECIAL REQUIREMENTS:
FIGURE 1
System is voltage specic. Please make sure •
you have a 12 or 24 volt EIC5000 depending
on your requirements.
(SEE FIGURE 1)•
Special sensor coils are required if:
- Actuator stroke is more than 2 ½" OR
- Less than 1" of piston shaft is exposed
when the actuator is fully retracted OR
- Actuator has external hydraulic connection
System will not work when actuator stroke is 1" or less•
If installing in an M80 or M120 Sport Tab kit, your actuator will have three molded rings as •
shown in Figure 1. Cut the metal rod to 6 ⁄" as indicated by score mark (see enclosed
instruction sheet for cutting the rod).

Check Special Requirements noted on the front cover of this manual before beginning installation.
If you are installing a preassembled actuator with the sensor wires already included, skip to step 6.
Installing New Upper Hinge with Sensor
Step 1 - Inside transom, with tabs in full up position, locate
trim tab hydraulic line. If there is no pipe nipple visible inside
the transom, you have a short through-transom tting connection,
(see Figure 2). Unscrew and remove actuator away from the
transom and use a 7/16" wrench to remove the tubing from
the upper hinge. Skip to step 3.
For standard installations, detach tubing from brass elbow (some
uid will drip out). While holding pipe nipples with vise grips,
unscrew brass elbow using 9/16" wrench. Do this procedure for
port and starboard cylinders (see Figure 3).
Step 2 - Outside transom, unscrew and remove actuator away
from the transom. Remove pipe nipple.
Step 3 - Start with the port side cylinder. Snap white
plastic clip on shaft protruding from bottom of cylinder.
IMPORTANT: This clip must be used to keep the spring
inside the cylinder compressed. Grasp cylinder upper hinge
with both hands and unscrew it counterclockwise from the
cylinder body (a small amount of uid may spill).

Step 4 - IMPORTANT: Use care when handling sensor
coils during assembly to avoid damaging wires. Insert
metal rod into piston, POINTED END DOWN. Make sure that
the O-ring is in place in new upper hinge with sensor coil.
Screw new upper hinge with Red Sensor Wire onto the
port side cylinder while keeping metal rod inserted into
center of sensor coil (see Figure 4). Tighten upper hinge
hand tight. You will nish tightening cylinder in Step 7.
Step 5 - Remove plastic clip from piston and repeat steps
2 - 4 for the starboard cylinder. Use upper hinge with
Green Sensor Wire for the starboard side.
Step 6 - Using template on the last page, drill 5/16" hole
in transom for the Sensor Wire (see Figure 5). Screw pipe

nipple into actuator upper hinge. Tighten nipple hand tight. Then, with vise grips, tighten two full
turns … NO MORE. Cover end of pipe nipple with masking tape. If you have the short throughtransom tting, using a 7/16" wrench, screw it in until the tting is snug; the shoulder of the
tting will just touch the plastic of the upper hinge.
Step 7 - Carefully feed Sensor Wire through 5/16" hole. Apply sealant to actuator upper hinge
surface around pipe nipple, screw holes, and cable. Secure actuator upper hinge to transom with
mounting screws. Grasp cylinder body with both hands and tighten (clockwise) securely.
Step 8 - Inside transom, remove masking tape from pipe nipples. Carefully wrap Teon tape
around male threads of pipe nipples. Holding pipe nipples with vise grips (to prevent them from
turning) re-secure 90 degree elbows. Re-attach hydraulic tubing, tightening nut nger tight.
Snug nut with 1/2" wrench. Do not over-tighten. Note: If you have the short through-transom
ttings, omit this step. Repeat for other side. Run Red and Green Sensor Wires to where you plan
to mount the EIC Module.
Step 9 - Mounting the EIC Display
Using the template on the last page, mark the location for your EIC Display and locate the centers
of the holes. Use a 2" hole-saw to cut the center hole and 3/16" drill for the four mounting stud
holes. Use a small bead of sealant around the perimeter of the display to seal. Plug the EIC Harness
(blue cable) into the back of the EIC Display. Use the 4 nylon thumb nuts to secure the display (use
care to avoid over-tightening).
