For each side of the boat, only one actuator per tab will have a
sensor — one for the port side and one for the starboard side.
It does not matter which of the dual actuators has the sensor
Step 7: 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 8: Mounting the Dual Acting Hydraulic Power Unit (DAHPU)
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
3" (8 cm). 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 4 5/8" (11.75 cm) apart. Drill 5/32" (4mm) 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 9: 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 10: Running Hydraulic Tubing
Single Actuator System: Run hydraulic tubing between the actuators and cut to length. Secure tubing as needed. (See next page, Fig-
ure 8 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 9 for Dual Actuator Systems.) Use tube bending clips at desired 90° bends in tubing to prevent kinking.
Step 11: Connecting Tubing to Actuators and DAHPUs
(See Figure 7) 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 ... 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 XPT System with an EIC5000.

(inboard or outboard). (See Figure 6)
Step 6: Adjust Negative Angle
Use a straightedge and adjust the negative angle to your specification.
(See Figure 5)
Push tubing to bottom of fitting while tightening.
Tighten nut one full turn past finger tight - NO MORE.
