Technical description

Your Adaptive Trim Tab System is the industry’s first trim system with position feedback.
This state-of-the-art system gives you immediate, precise, and repeatable control of vessel trim. With built-in intelligence, it can be integrated with Optimus Electronic Power Steering for complete vessel control. When integrated with Optimus, the system is called the Optimus Adaptive Trim Tab System.
The AdaptiveTrim Tab System consists of three primary components: the adaptive actuators, the sheet metal tabs, and the adaptive dial controller. The adaptive dial controller is unique in the industry with smart function buttons and an intuitive dial control that makes roll adjustment simple and obvious.
The system operates on 12VDC, and uses a Controller Area Network (CAN) bus for communications. The controller can control up to four trim tab actuators and precisely synchronize their movement.

Trim tab principles of operation

Trim tabs are plates, installed in pairs, used to control the pitch and roll of a boat by directing water as it flows past the transom. They work by harnessing the hydrodynamic forces exerted by moving water, so the boat must be in motion for the tabs to have an effect.

When a tab is lowered, the directed water flow will exert an upward force at the stern of the boat. If both tabs are lowered at the same time the upward force at the stern will force the bow down (pitch control). If only one tab is lowered it will force the bow down on the opposite side, causing the boat to roll (roll control). The combination of pitch and roll is the boat’s attitude.
By adjusting the boat’s attitude, the boat operator can get on plane faster, stay on plane at lower speeds, increase top speed, correct a small list, improve ride quality and visibility, reduce porpoising, and improve fuel economy.

Using the system

Basic features and operation

The dash-mounted Adaptive Dial Controller is designed for intuitive operation. The function of each interface feature is described below.

System Status Indicator
Displays the status of the trim tab system.
Steady green System is ready
Steady magenta Holeshot mode is activated, based on SOG
Steady lime green Holeshot mode is activated, based on RPM
Flashing blue System is in LED brightness adjustment mode
Flashing cyan The system has memorized the favorite position
Steady blue Tabs retracted automatically
Flashing yellow Controller has a non-critical fault (see section 6)
Flashing red Controller has a critical fault (see section 6)

Tab Position Indicator LEDs
Shows the position of port and starboard tabs. At full retraction a single LED is shown at the top. As the tabs are extended the LEDs will illuminate to show the tab position.

Bow Down

Lowers both tabs simultaneously, causing the bow to drop. Press and release to move both tabs a preset increment, or press and hold until the desired pitch is achieved. To enable fine control, the actuator speed is reduced for the first second the button is held, after which the actuators move at full speed for larger adjustments.

Bow Up

Raises both tabs simultaneously, causing the bow to rise. Press and release to move both tabs a preset increment, or press and hold until the desired pitch is achieved. To enable fine control, the actuator speed is reduced for the first second the button is held, after which the actuators move at full speed for larger adjustments.

Control Dial

Rolls the boat in the direction of rotation. Rotating the dial to starboard (clockwise) will cause the port tab to lower and the starboard tab to raise, causing the boat to roll to starboard. Turning the dial to port (counterclockwise) will have the opposite effect.

Use this control with caution: turn one click at a time and wait a moment to see how the boat reacts before making further adjustments. While this control can be used to correct a list due to uneven loading, best practice is to load your boat as evenly as possible, and to keep passenger movement at a minimum while underway at high speeds.
The relative positions of the tabs are maintained when using the Bow Down and Bow Up controls, so if you’ve used the roll control to correct for a list it will remain corrected as you alter the bow position.

Home

Press once to retract actuators to their fully retracted home position.
Use this button when:

• you encounter difficult sea conditions and need to raise the bow,
• preparing to load the boat onto a trailer,
• preparing the boat for lifting.

The home button will immediately override any automatic operation of the trim tab actuators and return them to home position. When the tabs reach the home position the trim tab position indicator LED will blink three times.

Favorite

The Favorite button has two functions, described in detail in section 5.2:

1. Set and recall a Favorite trim tab position.
2. Toggle Holeshot mode on or off.

You can switch between these functions by pressing and holding the
Favorite and Bow Up buttons together for three seconds. The system status indicator will briefly flash magenta to show the Holeshot function is enabled, or green to show the Favorite function is enabled.

Adjusting LED brightness

• Press and hold the Home and Favorite buttons together.
• The system status indicator flashes blue and the starboard tab position indicators all light up.
• As you continue to hold the buttons, the brightness of the LEDs will cycle through five levels.
• Release the buttons at the desired brightness level.

NOTE: Integrated brightness control
If your boat is equipped with Optimus Electronic Power Steering (EPS), the trim tab controller brightness can be adjusted using the CANtrak display’s brightness control. See your Optimus User Manual for instructions.

Preparing to trailer or lift the boat

• Press the Home button.
• The actuators will retract. When both tab position indicators show only one LED, the tabs are fully retracted.
• You are ready to trailer or lift the boat.

NOTICE! Material damage
Trailering or lifting the boat with the trim tabs extended may cause irreparable damage to the tabs and actuators.

Advanced features and operation

Setting and recalling a favorite position

With this function you can memorize a trim tab position and return to it at any time with a single press of a button.

NOTE
To use this function it must be enabled. See the description of the Favorite button in section 5.1.

Setting a favorite position:

• Press the Favorite button (fig. 2 1, page 1) for five seconds.
• The system status indicator will flash cyan three times to confirm the position has been saved.

Recalling a favorite position:

• Press the Favorite button.
• The tabs will adjust to the saved favorite position.

CAUTION! Varying sea conditions
If sea conditions have changed since you last set a favorite position, use caution when recalling it.

Adaptive Cruising Favorite setpoint

As you operate your boat and adjust the trim settings the system stores the latest stable setting as an Adaptive Cruising Favorite setpoint. A stable setting is one that is maintained for twenty seconds while Holeshot mode is activated and the engine RPM or speed over ground meets a preset minimum. The system status indicator will flash cyan when the system has memorized a favorite position.

The Adaptive Cruising Favorite setpoint is used by the Holeshot mode, and is only available in systems in which Holeshot mode is enabled by the builder/dealer.

Holeshot mode

NOTE: Holeshot mode prerequisites

• Holeshot mode requires an engine gear signal and either an engine RPM or GPS speed-over-ground source.
• If your boat is equipped with Optimus Electronic Power Steering (EPS), or has an NMEA2000 network with an engine gateway, you will likely have the engine gear and RPM signal, and you may have an SOG source.

Holeshot mode is a semi-automatic mode designed to get your boat up on plane quickly, with a minimum of operator involvement. It allows you to keep your focus on the water ahead of you and the safe operation of your boat.
When activated, Holeshot mode simplifies getting on plane. It will automatically deploy the trim tabs when it detects a Holeshot (a minimum engine RPM is reached), then retract them to the Adaptive Cruising Favorite setpoint as speed increases and the boat gets on plane.

To perform a Holeshot:

• Trim your outboard or sterndrive as you normally would for launch.
• Press the Favorite button (fig. 2 1, page 1).
• The system status indicator (fig. 2 5, page 1) will light up magenta or lime green. Magenta indicates that SOG is used to control deployment, while lime green indicates RPM is used.
• Increase throttle to your normal launch RPM.
• The Adaptive Trim Tab System manages tab deployment to get you up on lane quickly.
• Manually adjust engine trim and trim tabs as necessary for the conditions.

WARNING!
If sea conditions have changed since the last Adaptive Cruising Favorite setpoint was stored, the trim position may be unsuitable, and could potentially put the boat in a poor attitude for the conditions. Trim the tabs manually in this case. Always use your best judgment before activating Holeshot mode.

NOTE: Planing time limit
When RPM is used to control the tab deployment (i.e. no SOG source), there is a time limit between activation and when you must initiate the holeshot (by throttling up). The default limit is 15 seconds.

NOTE: Holeshot performance
The performance of holeshot mode is sensitive to tab size, system tuning, and throttle application. If holeshot performance is unsatisfactory, contact your dealer for assistance.

NOTE
If you cannot activate Holeshot mode:

• Your boat may not have an engine RPM or GPS speed-over-ground source.
• Holeshot mode may be disabled. See the description of the Favorite button in section 5.1.
• Check that at least one engine is running, no engines are in reverse gear, and that an Optimus joystick (if equipped) is not active.

NOTE: Holeshot automatic deactivation
If Holeshot mode is activated, it will automatically deactivate when:

• all engines are switched off
• any engine is shifted into reverse
• an Optimus joystick is activated Holeshot mode will automatically reactivate when at least one engine is running, no engines are in reverse, and the joystick is not active.

Automatic retraction

The trim tabs will automatically retract:

• when the ignition is switched off*,
• when the engine(s) are placed in reverse gear**,
• when Optimus joystick control or SeaStation are activated (when boat is so equipped).

Homing

When the trim tab controller is powered on, the system will go through a homing cycle. The trim tabs will retract at slow speed until the end of travel is detected.
This ensures the accuracy of the position feedback.

During the homing cycle the tab position indicator LEDs will light up sequentially from bottom to top. When the home position is detected the top LED will blink three times.

•  Battery switches must remain on.
• Requires a gear position signal. Standard on Optimus systems.

Faults and troubleshooting

Fault types

Non-critical faults
A flashing yellow status LED indicates a fault that does not affect the actuators.
An example is a faulty dial sensor. The trim tabs would still be operable using the bow up and bow down buttons, but the dial would not work.

Critical faults
A flashing red status LED indicates a critical fault that will prevent one or both actuators from operating.

Conditions that can cause a critical fault include:

low or high battery voltage (these will reset automatically if the voltage condition is corrected).

Actuator faults
A flashing tab position LED indicates an actuator fault. The LED corresponding to the last known position will flash.

Conditions that can cause an actuator fault include:

• an actuator harness is unplugged, corroded, or otherwise not making a connection.
• a short circuit in the actuator or harness.
• something is preventing the tab from moving.
• a mechanical fault in the actuator.

Fault recovery

In the event of a critical fault that does not clear you will usually need to take your boat to a marine technician (or an Optimus-certified dealer when equipped with Optimus) for diagnosis and repair. If you are on the water, experience and judgment may suggest that you return to port immediately, especially if conditions are changing.
A tab position that has the boat in a good running attitude now may be a poor tab position if the wind changes.
If the tabs are stuck in a position that gives the boat a poor running attitude, the best response is to slow down. The slower the boat moves the less effect the tabs have on attitude.

Troubleshooting

System: if the CANtrak is on, check the connections in the CAN2 network. If the CANtrak is not on, check the Optimus EPS ignition sensing wire.
 | Adaptive trim tab system: check the ignition sensing wire.
The system status LED is flashing yellow.| Holeshot mode is activated, but the speed source is missing.| Multi-engine boats: check that all engines are running.
Contact your dealer
If one or both tab position indicators are off, the tab(s) have failed to home correctly| Try pressing the Home button again.
Check that nothing is physically preventing the tabs from moving to the home position.
Contact your dealer.
The system status LED is flashing red. Tab position indicators are solid.| Battery voltage is too low or too high.| Check battery voltage.
The system status LED is flashing red. One or both tab position indicators are flashing.| Tab(s) with blinking position indicators are not making position.| Check that nothing is physically preventing the tabs from moving. If there is no obstruction, contact your dealer.
Holeshot mode won’t enable.| Your boat is not equipped with a speed source.| Contact your dealer.
The boat builder or system installer has deactivated this system.| Contact your dealer.
Holeshot performance is poor.| Sea conditions are different than the mode was tuned for.| Adjust trim manually.
Holeshot settings have not been optimized for your boat.| Contact your dealer.

Maintenance and cleaning

NOTICE! Material damage

• Do not use acetone, or cleaners containing ammonia, acids, or any other corrosive ingredients.
• Some products formulated for cleaning fiberglass hulls are known to aggressively corrode stainless steel shafts. If using a hull cleaner, avoid overspray on to the actuators. Rinse off any overspray immediately with fresh, clean water.
• Do not use sharp or hard objects to clean the controller. Damage to the keypad membrane may occur.
• The controller bezel has a drain hole at the bottom. Do not spray with water from below.

Whenever the boat is out of the water:

• Rinse the tabs and actuators with clean, fresh water. Avoid hitting the actuator with high pressure spray from a pressure washer.
• Remove any marine growth such as weeds, barnacles, and shellfish from the tabs and actuators.
• Inspect tabs and actuators for damage, corrosion, or anything that might impair function.
• Check the condition of zinc anodes, if present, and replace if necessary.
• Inspect the electrical harness for wear or damage.

NOTICE! Corrosion

• The stainless steel tabs are corrosion resistant, but not corrosion proof.
• Properly installed zinc anodes will help prevent galvanic and stray current corrosion.
• Some minor corrosion on the tabs may still occur and is not a warrantable defect.

Controller:
Clean the controller occasionally with a damp cloth.

NOTE: Invasive species
Do your part to protect our waterways from invasive species. If trailering your boat to a different body of water than you normally boat in:

• Thoroughly inspect trim tabs and actuators for any weeds and  shellfish.
• Many boat builders mount the trim tabs in hull pockets that can easily hide invasive species. Be sure to check these recesses.
