Step 4: Mounting the Actuators to the Transom
Carefully remove hex plugs from the fluid holes in the actuator upper mounts. The actuators contain a large amount of automatic
transmission fluid. Apply Teflon tape on male threads of pipe nipples and tighten into the actuator upper mounts. (See Figure 5)
Note: Before pushing the pipe nipples and sensor plugs through the holes in the
transom, cover the ends with masking tape to prevent damage or debris from
entering the system.
Carefully insert sensor wire through center hole. Pull all slack sensor wire into the boat.
Apply waterproof sealant on surface of the upper mount, around pipe nipples and screw holes.
Insert pipe nipples through transom and secure actuator upper mounts to transom with
8mm (5/16") fasteners. Actuators should be through-bolted to transom.
Tighten 5/16-18 x 1 1/4" machine screws to attach the actuator to the trim tab.
Step 5: Filling the Dual Acting Hydraulic Power Unit (DAHPU)
Remove the Lexan cover from the DAHPU. Then remove the plug from the filler stack located at the front left corner of the reservoir.
Fill fluid to reservoir if necessary using any type automatic transmission fluid (ATF).
Step 6: Mounting the Dual Acting Hydraulic Power Unit
Install Dual Acting Hydraulic Power Unit (DAHPU) in a convenient, dry location. Important: The DAHPU must be mounted in a dry
enough location to avoid drenching. Allow space above the DAHPU so that it may slide into its mounting bracket — about
8 cm (3"). This will also be enough space to remove Lexan cover once installed. Use the mounting bracket as a template, being careful
not to flex or bend it. The upper holes on the DAHPU mounting bracket should be 11.75 cm (4 5/8") apart. Drill 4mm (5/32") pilot holes for
the mounting bracket. Put the four #10 x 1" screws into place but do not fully tighten. Run ground wire and wire harness down the back of
the DAHPU while sliding it into bracket. Now tighten screws on mounting bracket.
Step 7: Attaching Fittings
Inside the transom, remove the protective tape from the pipe nipples. Check that the pipe nipples are clean and clear. Then apply Teflon
tape on male threads of pipe nipples and tighten the 90° brass elbows to pipe nipples.
Step 8: Running Hydraulic Tubing
Single Actuator System: Run hydraulic tubing between the actuators and cut to length. Secure tubing as needed. (See next page,
Figure 7 for Single Actuator Systems.) Dual Actuator Systems: Run tubing from the DAHPUs to the desired Brass Line-T location as
shown. Secure as required. (See Figure 8 for Dual Actuator Systems.) Use tube bending clips at desired 90° bends in tubing to prevent kinking.
Step 9: Connecting Tubing to Actuators and DAHPUs
(See Figure 6) Insert tubing through the nut with ferrule and into the 90° elbow.
Push until the tubing bottoms in the fitting. While continuing to bottom the tubing in
the fitting, tighten nut “finger tight,” then one full turn with a 13mm (1/2") wrench …
NO MORE. Do the same to connect the tubing to the Brass Line-Ts, and then from the Brass
Line-Ts to the DAHPUs.
Step 12: Installing Electronic Indicator Control
Wire control and electrical system per diagram and instructions in the next section for a
SST System with an EIC5000.
Tighten nut with 13mm (½") wrench one full turn past
finger tight - NO MORE.
Push tubing to bottom of fitting while tightening.
