WARNING!

Safety instruction: Indicates a hazardous situation that, if not avoided,

could result in death or serious injury.

CAUTION!

Safety instruction: Indicates a hazardous situation that, if not avoided,

could result in minor or moderate injury.

NOTICE!

2 General safety instructions

The manufacturer accepts no liability for damage in the following cases:

• Physical damage to the product.

• Damage due to incorrect installation or connection voltage.

• Alterations to the product.

• Use for purposes other than those described in the operating manual.

The CE declaration of conformity can be requested from the manufacturer (contact

information on the back of this manual).

2.1 General safety

• Read and understand all instructions included with your system prior to use.

• Disconnect power from the actuators (with battery switches or circuit breaker)

before working at the transom of the boat.

• Only use the trim tab system as intended.

• Do not use tabs as a boarding step.

•

When liing the boat, do not place the liing straps or forks on the tabs or actuators.

• Do not push or pull on the tabs or actuators when putting the boat on or oﬀ

a trailer.

• Do not tie oﬀ or secure anything to the actuators.

• See an Optimus-certiﬁed dealer for repairs if the trim tabs, actuators, or controller

are modiﬁed, damaged or not working correctly.

•

The controller and actuators are not user serviceable; do not attempt to disassemble.

2.2 Safe operation

• The trim tab actuators are powerful mechanical devices that can cause injury.

Ensure no one is at risk of being injured before operating a tab when

swimmers are in the water, or when operating the tabs on a trailer with people

or children around.

• The trim tab system is not a toy. Do not allow children to operate the system.

WARNING!

Exercise sound judgment when using trim tabs in challenging sea

conditions. In some cases the safest action is to run with tabs fully

retracted.

3 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.

4 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.

3.2 Controller operating and display elements

WITH TRIM TABS IN USE WITHOUT TRIM TABS

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.

5.1 Basic features and operation

The dash-mounted Adaptive Dial Controller is designed for intuitive operation. The

function of each interface feature is described below.

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)

System

Status

Indicator

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.

Control

Dial

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, aer which

the actuators move at full speed for larger adjustments.

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, aer which

the actuators move at full speed for larger adjustments.

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.

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 liing.

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.

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.

5.1.1 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.

Optimus Adaptive Trim Tab System | Adaptive Trim Tab System

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.

NOTE

To use this function it must be enabled. See the description of the

Favorite button in section 5.1.

5.1.2 Preparing to trailer or li 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 li the boat.

NOTICE! Material damage

Trailering or lifting the boat with the trim tabs extended may cause

irreparable damage to the tabs and actuators.

5.2 Advanced features and operation

5.2.1 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.

Setting a favorite position:

Press the Favorite button (ﬁg. 21, 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.
