How to Use Your BXT Trim Tab System

Getting and Staying Trimmed

Your vessel will “break over” or plane at a particular speed. This speed is determined by weight distribution, water conditions, etc. Your BXT trim tabs enable you to plane at lower speeds. By depressing the helm control in the “Bow  Down” position, your trim tabs move down. This will raise your stern and lower your bow, getting you up on plane faster and increasing your speed.

Your Vessel’s Optimum Attitude
Determine your optimum attitude by conducting this test: Get out and run at full speed in calm water. Notice the bow in relation to the horizon. This should be your best running attitude. You can use your trim tabs to recreate this  “optimum attitude,” correcting for changes in weight distribution, speed and water conditions.
Getting Used to the “Feel” of Your Tabs
When learning to use the BXT, begin by pressing the helm control in half- second bursts, allowing time between corrections for gradual trimming. Do not over-trim. An over-trimmed vessel will “plow” or “bow-steer.” If you over- trim, simply press “BOW UP” and the bow will rise.
Trimming From a Bridge or Tower
When steering from a bridge or tower, a good trimming method is to watch the bow spray, stern wake, or the rooster tail. An untrimmed vessel will produce spray farther aft of the bow and it will produce a larger wake. When trimmed, the  bow spray is farther forward, the wake is reduced, and the rooster tail is smaller and farther behind the boat. You’ll also notice that the engine RPM may increase when the boat is properly trimmed.
Running in Rough Water
When running in a chop, press “BOW DOWN”. This will bring the “V” of the hull in contact with the waves rather than having the waves pound the flatter portion of the hull and your passengers. In a following sea or when running an inlet, the trim tabs should be fully retracted for maximum rudder response.
Correcting for a “Listing” Condition
The BXT trim tabs may be operated individually so that you can correct for a “listing” condition. Your control is designed so that you can use it “intuitively.” Do not think about what the trim tabs are doing, just concentrate on your bow. If  the port bow is high, push the port-side “Bow Down” direction. If the starboard bow is high, push the starboard side “Bow Down” direction until the “listing” condition is corrected.
Safety Precautions

• Do not over-trim, particularly at high speeds as the bow may dig in and wave action may cause the vessel to veer.
• While underway, do not move one trim tab significantly farther down than the other as undesirable listing could occur.
• For best maneuverability, trim tabs should be fully retracted in a following sea, or when running an inlet.
• Improper use of trim tabs can cause an unexpected attitude change of vessel, which could lead to an unsafe condition.

The BXT System will have a significant effect on the operation and versatility of the vessel. The best learning method is to spend time getting familiar with your vessel’s reaction to trim tabs. Always operate your vessel with safety first in mind.

Installation Instructions for Dual Acting BXT System

READ THIS FIRST BEFORE BEGINNING INSTALLATION
IMPORTANT FOR ACTUATOR INSTALLATION ON ALL BOATS
Actuators must be installed perpendicular to the trim tabs and parallel to each other. Stainless steel is not flexible. Measurements have to be precise.
BE CAREFUL NOT TO ROTATE THE ACTUATOR SHAFT — ROTATING THE SHAFT WILL DAMAGE THE INTERNAL SENSOR.
IMPORTANT: FOR BOATS KEPT IN SEAWATER
THIS SYSTEM MUST BE PROTECTED FROM ELECTROLYSIS AND GALVANIC CORROSION — THIS DAMAGE IS NOT COVERED UNDER WARRANTY
To provide protection from electrolytic corrosion a zinc anode must be applied to each tab. In the case of tabs installed on the boat as original equipment by the builder, a bonding system may be utilized for your particular model. The BXT system top portion of the actuator and the actuator shaft are electrically isolated from each other. Therefore the trim plane and the upper part of the actuator must be individually protected or integrated into a bonding system.
MUST USE ANTI-FOULING PAINT
Trim tabs and actuators should be painted with anti-fouling paint to prevent fouling by marine growth.
Follow paint manufacturer’s recommendations for proper priming and painting of stainless steel.
NOTE: Do not paint under zincs — this prevents electrical contact with trim tabs.
Step 1: Positioning Tabs
Position the trim tabs against the transom and check to see that the upper mounts of the hydraulic actuators do not center on an inside obstruction. If they do, reposition tabs slightly outboard. The further outboard the tabs are mounted,  the greater the lateral (side-to-side) control. Position tabs 8-10 cm (3″-4″) from the chine and run towards the centerline of the boat.
Step 2: Securing Tabs
Attach the hinge plate and backing plate (mounting plates), and trim tab with 6mm (1/4″) stainless steel fasteners along the bottom of the transom. (See Figure 1) Using the backing plate as a template, mark screw hole locations. Assemble mounting plates and tab, dip screws in marine epoxy before running in. Support the trim tab from below, then slide trim tab between backing plate and hinge plate before running screws tight. Snug screws down to secure mounting plates and trim tab to transom. If the transom is curved, a shim must be made of a suitable material to provide a flat mounting surface.

Step 3: Drilling the Holes for Actuators

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 5/8″ 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 2. 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.

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 three 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 3.

5. Drill the marked 9mm (11/32″) 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 5/8″ hex head machine screws. DO NOT TIGHTEN.

IMPORTANT INSTALLATION NOTICE: MAKE SURE ACTUATOR UPPER MOUNTS FACE THE CORRECT WAY
The upper mount is able to pivot through 180 degrees but there is only one correct way to install it. The pointed end of the upper mount must face up as shown here. PROCEED TO STEP 4 ON PAGE 6 TO COMPLETE THE INSTALLATION.

DUAL ACTUATOR SYSTEMS (2 ACTUATORS PER SIDE)
These systems consist of two actuators per trim tab — one with sensor and one without sensor. 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.
IMPORTANT: The hole for the sensor wire must be accurate — match the paper template exactly so that the wire goes through the transom easily. Be careful not to crush or pinch the wire while mounting the actuator.
IMPORTANT INSTALLATION NOTICE:
MAKE SURE ACTUATOR UPPER MOUNTS FACE THE CORRECT WAY
The upper mount is able to pivot through 180 degrees but there is only one correct way to install it. The pointed end of the upper mount must face up as shown here.

(See Figure 4) For this step, use the two actuators WITHOUT the sensor wires. You will do this for each 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.
2. Support the trim tab assembly from below while positioning against the transom. Attach both actuators without sensors to the trim tab using the supplied 5/16-18 x 5/8″ hex head machine screws.
3. Mark the outline of the three mounting holes in the upper mount. Remove the actuators from the trim tab and set aside.
4. Take both actuator paper templates and put them in position — the paper template with sensor hole should be inboard, and the template without sensor hole should be outboard. Align the templates and tape to the transom. The  templates should be used to mark and drill the sensor holes and pipe nipple holes. Drilling a small pilot hole first helps locate an accurate center for each hole. Based on the template, for the actuators with a sensor, drill a 19mm  (3/4″) hole in the transom for the sensor wire. Drill the marked 9mm (11/32″) mounting holes for each actuator. And drill the marked 12mm (1/2″) holes for the pipe nipples.
5. Once all the holes are drilled, mount the actuators to the trim plane using the supplied machine screws. DO NOT TIGHTEN.

Note: Actuators WITH sensors should be mounted inboard. Actuators WITHOUT sensors should be mounted outboard.
For Each Side of the Boat:

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 5/8″ 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- St, and then from the Brass Line-St to the DAHPUs.

• DO NOT connect to EIC Relay Module grounding stud. (See Figure 9 above)

Step 6: Connecting the Sensor Wires

• Plug the Green Sensor Wire into the Starboard Sensor Wire Connector (green collar) on the EIC Relay Module (#6 on System Schematic).
• Plug the Red Sensor Wire into the Port Sensor Wire Connector (red collar) on the EIC Relay Module (#6 on System Schematic).

Step 7: Mounting the EIC Display at the Helm (#1 on System Schematic)
Follow these instructions for both the Lower Helm and Upper Helm EIC Displays

• Using the enclosed paper EIC Display Template, mark the location for your EIC Display and locate the centers of the holes on the template.
• Use a 51mm (2″) hole-saw to cut the center hole and 5mm (3/16″) drill for the four mounting stud holes.
• Use a small bead of sealant around the perimeter of the display to seal.
• Using the 4 nylon thumb-nuts, secure the display. (Do not over-tighten.)

NOTE: IF YOU HAVE A SINGLE STATION SYSTEM, JUMP TO STEP 13.

Step 8: Mounting the EIC Bridge Box (#4 on System Schematic)

• Mount the EIC Bridge Box within the length of the thick gray EIC Wire Harness (Part# EIC301, #3 on System Schematic) that will plug into the Lower Helm EIC Display.

Step 9: Connecting the EIC Wire Harness (Blue) to the EIC Bridge Box

• Plug the EIC Wire Harness (Part# EIC201, #5 on System Schematic) into the EIC Relay Module (#6 on System Schematic).
• Plug the other end of the Blue EIC Wire Harness into ANY of the three connectors on the Bridge Box.
• The cable must be properly strain relieved at both ends to support the weight of the blue cable at the Bridge Box.

Step 10: Connecting the Upper Helm EIC Display (secondary) to the EIC Bridge Box

• Plug the thin gray EIC Bridge Wire Harness (Part# EIC801, #2 on System Schematic) into the back of the Upper Helm EIC Display.

• Plug the EIC Wire Harness into the remaining connector on the Bridge Box.
• The cable must be properly strain relieved at both ends to support the weight of the cable at the Bridge Box.

Step 12: Cutting the Wiring for Upper Helm EIC Display (secondary)

• DO NOT connect the orange and purple wires at the Upper Helm EIC Display. Cut the orange and purple wires off the display.
  GO TO STEP 14.

FOR SINGLE STATION SYSTEM ONLY
Step 13: Running the EIC Wire Harness (Part# EIC201, #5 on System Schematic)

• Plug the EIC Wire Harness (Blue Cable) into the back of the EIC Display and run to the location of the EIC Relay Module.
• Plug the Blue EIC Wire Harness into the EIC Relay Module.
• The cable must be properly strain relieved at both ends to support the weight of the blue cable. GO TO STEP 14.

FOR BOTH DUAL AND SINGLE STATION SYSTEMS
Step 14: Connecting the Wiring for the Lower Helm EIC Display (primary)

• Connect the Purple wire containing the inline 1.5 amp fuse to the ignition switch or any 12 or 24 volt circuit that turns on with the ignition. This wire is used to initiate Auto Tab Retraction when the ignition is switched to the off position.

• Connect the Orange wire containing the inline 1.5 amp fuse to a source that supplies power to the boat’s electronics and/or gauges.
  This wire senses the power and shuts off the display when the helm power is shut off.
  Step 15: Connecting the Power and Ground on the EIC Power Cables (#7 on System Schematic) to the EIC Relay Module

• Attach the black wire to battery ground. Attach the orange wire with inline fuse to the same battery positive power source.

Calibration and Operation

Once installation of the BXT System is complete, use the EIC to bleed the system by holding down the “BOW DOWN” position for 15 seconds, then “BOW UP” for 15-20 seconds. Repeat 3 times. This will purge air from the system. Then place both tabs in the “full down” position and check all hydraulic connections for leaks. Bring the tabs to the full UP position and check the fluid level. Add ATF if necessary. Also check for leaks in the “UP” position.
Calibration — NOTE: Calibration must be done at the Lower Helm EIC Display

1. The port and starboard red LEDs will flash alternately, indicating that the system is not calibrated.
2. Press and hold the “sun” and “moon” buttons on the Lower Helm EIC Display  simultaneously for approximately 3 seconds. Both the port and starboard lower yellow LEDs  will begin to flash. Release the “sun” and “moon” buttons.
3. Using the Lower Helm EIC Display, run both trim tabs to the full down position (BOW DOWN on the control). Make sure the tabs go all the way DOWN by holding the buttons  for at least 15 seconds. (Holding the buttons after the tabs are down will not harm the system).
4. A few seconds after the tabs are all the way down the port and starboard upper yellow LEDs will begin flashing. Again, using the Lower Helm EIC Display, run both tabs to the full up position (BOW UP on the control). Make sure the tabs come all the way UP by holding the buttons for at least 15 seconds.
5. The upper and lower yellow LEDs will then light up solidly, indicating that the EIC is calibrated and ready to operate. If you  wish to recalibrate the EIC at any time, simply bring the tabs to the full up position, press and hold the  “sun” and “moon”  buttons down and repeat the calibration instructions.

Operation
The intensity of the display LEDs may be adjusted by pressing the “sun” button to brighten and the “moon” button to dim the display.

EIC Display Diagnostic Information

Port and starboard red LEDs alternately flash: EIC requires calibration. Refer to calibration information above.
Upper yellow LED flashes on port or starboard side: Indicates the EIC Display is not receiving a sensor signal. If the port upper yellow LED flashes the fault is in the port sensor or wires. A flashing yellow LED on the starboard side would  indicate a fault on the starboard sensor or wires. Switching the sensor connections on the EIC Relay Module will confirm the diagnostic code if the flashing LEDs switch sides. If the problem switched sides, check the suspected faulty  actuator with an Ohm meter at the EIC sensor cable plug. The reading should be in the 220-260 Ohm range. If the sensor readings are good, check for faulty connections (corrosion or broken wires).

Dual Acting BXT System Troubleshooting Guide
Before proceeding with the tests below, verify that each orange power wire is connected to a live positive power source, and that the fuses* are not blown. Make sure that each black wire has a good connection to ground.** After this is complete, conduct the tests below.
STEP 1A — Troubleshooting for Port DAHPU and Port Dual Acting Relay Module
Unplug the port Dual Acting Hydraulic Power Unit (DAHPU) from the Port Dual Acting Relay Module (RMPORTDA). Using a hot lead, directly power the DAHPU plug as shown below:

If the port trim tab does not move when DAHPU is powered direct, then the port DAHPU or port actuator(s) are faulty. Contact Bennett Marine.
If the port trim tab still moves, plug the DAHPU back into the Port Dual Acting Relay Module (RMPORTDA). Unplug the RMPORTDA from the EIC Dual Pump Cable (Y-Harness). Take the RMPORTDA and using a hot lead directly  power the three-color wire pigtail featuring a red heat shrink collar as shown below:

If the port trim tab does not move when powered through the Port Dual Acting Relay Module, then the RMPORTDA is faulty.
STEP 1B — Troubleshooting for Starboard DAHPU and Starboard Dual Acting Relay Module
Unplug the starboard Dual Acting Hydraulic Power Unit (DAHPU) from the Starboard Dual Acting Relay Module (RMSTBDDA). Using a hot lead, directly power the DAHPU plug as shown below:

If the starboard trim tab does not move when DAHPU is powered direct, then the starboard DAHPU or starboard actuator(s) are faulty.
Contact Bennett Marine for assistance.
If the starboard trim tab still moves, plug the DAHPU back into the Starboard Dual Acting Relay Module (RMSTBDDA). Unplug the RMSTBDDA from the EIC Dual Pump Cable (Y-Harness). Take the RMSTBDDA and using a hot lead  directly power the three-color wire pigtail featuring a green heat shrink collar as shown below:

If the starboard trim tab does not move when powered through the Starboard Dual Acting Relay Module, then the RMSTBDDA is faulty.

• This system could contain up to five (5) fuses — three (3) 1.5 amp, with two (2) 10 amp (24V) or two (2) 20 amp (12V). The boat builder could have replaced these fuses with breakers, or used breakers and inline fuses.
  There are five (5) ground (black wires) — two (2) DAHPUs, two (2) Dual Acting Relay Modules and one (1) EIC Relay Module.
  STEP 2*
  Before proceeding with the tests below, verify that each orange power wire is connected to a live positive power source and that the fuses are not blown. Make sure that each black wire has a good connection to ground.** After this is  complete, conduct the tests below.
  If the trim tab(s) is still operational after conducting the tests in Step 1, then either the Y-Harness or EIC Relay Module is at fault. Perform the test below by removing the EIC Dual Pump Cable (Y-Harness) from the EIC Relay Module. Using a hot lead, directly power the end of the Y-Harness just removed from the EIC Relay Module (four wires in the plug) as shown below:

If the trim tab(s) is still not operational when powered through the Y-Harness, then the Y-Harness is faulty.
If both trim tabs operate as they should after conducting the above test, then the EIC Relay Module may be faulty.
Conduct the following test by directly powering the shorter, unused cable on the EIC Relay Module:

If the trim tab(s) is still not operational when powered through the EIC Relay Module, then the EIC Relay Module is faulty.
If both trim tabs operate properly when the above test is conducted, then either the EIC Display or the EIC Wire Harness is at fault.
Ensure that both ends of the EIC Wire Harness are seated firmly in the plugs, and that the EIC Display’s orange wire has proper voltage.

• This system could contain up to five (5) fuses — three (3) 1.5 amp, with two (2) 10 amp (24V) or two (2) 20 amp (12V). The boat builder could have replaced these fuses with breakers, or used breakers and inline fuses.
  ** There are five (5) ground (black wires) — two (2) DAHPUs, two (2) Dual Acting Relay Modules and one (1) EIC Relay Module.
