Basic Safe Operation

CONGRATULATIONS!

You have just purchased the finest trim tab system in the world! Welcome to the future.

Lenco trim tabs make the single most important dierence in the way your boat rides and
performs. They are optional on some boats but should be as standard as power trim and tilt. Lenco
trim tabs make your boat ride smoother, drier, faster and with increased safety whether on a small
ski or a mega-yacht. Our ball screw design makes our tabs more reliable and twice as powerful
as typical hydraulic trim tabs. Coupled with any of our trim tab switches, they also perform with
instant response which makes them more precise and user-friendly.

Our goal is to manufacture products that simply make boating more enjoyable.

All Lenco Marine LLC Trim Tab products are CE certified

Basic Safe Operation:

While the boat is underway, do not move one tab up or down significantly as this may cause listing.

While at higher speeds, do not over trim. This causes the bow to lower quickly, resulting in a reduction of
speed and may cause the boat to veer.

When running in a following sea the tabs should be fully retracted. This allows for optimal performance.

While operating trim tabs, use caution. Improper use of trim tabs may cause accidents and/or injury.

Safety & Trim Tab Overview

lencomarine.com

Safety

WARNING: Operating the actuators at a high duty cycle without cooling from ambient water

may damage the actuator and cause failure.

WARNING: Auto mode function warning:

Quickly reducing from high to low speed causes the trim tabs to fully deploy.

Full deployment of the tabs at high speed will cause a very rapid reduction in the boat's
speed, resulting in any heavy object not securely tied down being thrown forward, including
passengers.

Trim Tab Overview:

Whether Lenco trim tabs operate independently of one another, or in unison, they provide optimal
performance by redirecting water flow at the transom of the boat. Lenco trim tabs have been designed
to improve the overall attitude of a boat. When used properly, Lenco trim tabs improve the ride, reduce
drag, increase speed, and improve the fuel eiciency of your boat.

WARNING: The trim tab system described in this document must be applied according to

these instructions:

• Unforseen responses to sea states may cause adverse operating conditions

• Unforseen responses to keypad inputs may cause adverse operating conditions

• Unforseen actuator performance may cause adverse operating conditions

The operation of Lenco trim tabs is basic.
The two stainless steel planes are mounted
with the actuators on the transom of the boat.
When the tabs are lowered, the water flow
is redirected creating an upward force at the
stern of the boat. When the stern rises, the bow
will lower.

Since Lenco actuators are electromechanical,
they provide an immediate response at the
touch of the keypad. This applies to all of our
trim tab keypads and switch kits. Since each
boat is dierent in weight, length, speed and
performance, it takes practice to understand
how your boat reacts with trim tabs installed.
Lenco trim tabs allow your boat to get on
plane faster and continue to stay on-plane
at lower speeds. This improves the captain’s
visibility and the overall safe operation of your
boat. When adjusting the trim tabs, use short
momentary taps of the keypad and rotary dial.
To become knowledgeable on how your boat
performs with Lenco trim tabs, remember,
practice makes perfect.

Without Trim Tabs

With Trim Tabs

When the tabs are
lowered, the water
flow is redirected
creating an upward
force at the stern of
the boat.

c. Pressing the ALL DOWN button on the dial face will turn ON

pitch control and a single right hand LED will illuminate.

d. Rotate dial counterclockwise to next menu for third LED on the

left side of the dial.

The following two settings setup your boat’s on-plane pitch control.

Set Pitch Control

On or O

WARNING: On power up actuator will attemp to home and retract fully, ensure trim tabs are
clear from any obstructions or personnel to prevent injury:

To prepare for first launch with new system, plan an on-water location to commission the
system with enough area to complete circles and high speed runs, with relatively smooth water
(1 foot or less of water chop is preferred). Note: On first time power up Pro Control Auto will be
in a commisioning mode with lights flashing fast in sync!

The following two steps must be completed on open water with less than
1’ of wave chop. Running the boat in a straight line over a reasonable
distance, 3/4 mile or more. The sea state should be consistent throughout
this commissioning, e.g. the boat must not porpoise.

Boat should be loaded and weighted in the same manner as expected
normal use for best outcome: fuel; number of people; gear; etc….

3. Low speed pitch control.

This step in the commissioning process captures the lowest speed
at which the vessel is expected to plane. The objective of this step
is to gradually ramp up speed by applying throttle until the bow rises
to its peak and begins to fall. This will be indicated by blinking LED's
on the keypad and captured by pressing the DIM ( ) button.

a. Prior to getting underway use the ALL UP/DOWN buttons on

the dial face to set the actuator extension to 50%, represented
by five LEDs on the right side of the dial lit.

• Only the LEDs on the right hand side of the dial will light up
and represent actuator extension of both actuators.

• The two lower DOWN and two lower UP buttons below the dial
are locked out.

• Keep in mind, if you return the throttle speed control back to
neutral, the TABs will auto retract.

b. Slowly increase vessel speed until all LEDs blink.

c. If the LEDs stop blinking you can slow back down gradually to

reengage the pitch control. The LEDs will begin to blink again.

d. Maintain your boat’s speed so that the dial LEDs consistently blink.

e. Wait 5-10 seconds with consistent blinking, if possible, before pressing

the DIM ( ) button, storing the target (best practice).

f. Press and hold DIM ( ) button 1 second to store the slow pitch control

target, both Left and Right-side LEDs will flash three times. The left side
LEDs will return to steady state lit. This indicates that the slow pitch
control has been stored.

g. Manually retract the actuators to 0% using the ALL UP

button on the dial. No right hand LEDs lit.

h. Rotate dial counterclockwise to next menu with four LEDs

lit on the left hand side of the dial.

Sea Trial Commissioning

4. High speed pitch control set up.

This step in the commissioning process captures the high speed
pitch angle of the vessel. The objective of this step is capture the
pitch angle at Wide Open Throttle (WOT) using the DIM ( ) button.

a. Bring the vessel back to idle speed to automatically fully

retract the tabs or use the All Up button on the dial face to
bring both tabs to 0%.

b. Increase vessel speed up to maximum WOT.

c. At WOT the vessel must run smoothly, without porpoising.

If the vessel is bobbing across the water use the engine trim
to smooth the ride.

d. If engine trim will not smooth the ride then deploy tabs a

minimal amount by pressing the ALL DOWN button on the
dial face until the porpoising is gone.

e. Maintain WOT speed for 3 to 5 seconds in a straight line if possible

(best practice).

f. Press and hold the DIM ( ) button for 1 second to store target. All LEDs,

left and right, will flash three times. This indicates that the high speed
pitch control target has been stored.

g. Slow vessel down to idle.

High Speed Pitch

Control Setup

5. Exit Commissioning process

a. Simultaneously hold the AUTO and HOLD button for 3 seconds.

The keypad controls are now in the manual mode. In order to enter
Auto Mode press the AUTO button.

WARNING: To save programmed settings,
the system must be shut down with the vessel's
ignition switch prior to powering batteries o.

Options for other outcomes:

1. Change Delta drop detection to a high degree value, (menu 5 in calibration).

a. Changing the LEDs in menu 5 of (Calibration Menu) will increase the amount

the vessel bow has to fall in order to be declared on plane. The outcome
will be more TAB used at lower speeds for better BOW control with each
increase of LED.

Caution: Over application of tabs is possible which results in poor vessel
handling and bow steering.

Auto Keypad Operation

Auto Keypad Operation

Enabling AUTO mode:

After completing the Calibration and Commissioning for your boat the
AUTO trim tab control mode may be safely used.

1. Press and release the AUTO button. The green LED will illuminate
on the AUTO button.

(AUTO remains active if the dial is used or the All Up or Down button
on the dial face is used).

2. Rotating the dial changes the boat’s roll target and enables HOLD
mode. The AUTO LED and the HOLD LED will be lit.

3. Adjusting the boat’s target pitch using the All Up or Down button on
the dial enables HOLD mode. The AUTO LED and the HOLD LED
will be lit.

Note: Throttle changes to increase or decrease speed will not
change AUTO or HOLD tab settings.

4. Pressing the AUTO button again disables the auto and hold modes.

Note: Pressing, any of the four lower buttons also disables the auto
mode: port DOWN or UP; or starboard DOWN or UP. This places the
system in manual mode.

lencomarine.com

Enabling Auto

Mode (First Time)

When Auto is O:

When AUTO is OFF, pressing the HOLD button temporarily maintains
the boat’s position. The AUTO and HOLD LED's will be illuminated.

Throttle changes to increase or decrease speed will not change the
manually set HOLD boat position.

The pitch and roll target settings in HOLD mode are temporary, and will
be lost when disabling HOLD, applying independent control using any
of the four lower buttons, or turning the vessel key switch o.

When AUTO is not active, any manual adjustments made using the
dial, All Up or Down buttons, or four lower buttons the actuators will
maintain their set position regardless of the boat’s position.

Flybridge Keypads

Flybridge keypads do not allow
configurations or performance adjustments,
these must be done at the main keypad
station. All other functions and controls are
the same as the main keypad station.

Converting to Tab Centric

The system can be converted from ‘boat centric’ to
‘tab centric’, this reverts the buttons and dial control to
the opposite trim tab. The system is automatically set
to ‘boat centric’.

Example: the port lower UP button controls the
starboard tab in ‘boat centric’.

In Tab Centric mode the port UP button will control the
port tab. We do not recommend setting up the vessel
in this configuration.

Trim Tab
Maintenance Tips:

Cleaning your Trim Tabs

The attractive surface appearance of stainless steel
cannot be regarded as completely maintenance­free. Our 304 Series Stainless Steel may in fact
stain, discolor, or accumulate a layer of surface
contamination (dirt and grime) during the normal
course of the life cycle. Minute particles of dust
and rust may adhere to the stainless steel during
shipping, installation, or storage at OEM or retail
locations. Also, please remember that some types
of stainless-steel fasteners tend to “bleed” over
the tabs and onto the boat. To achieve maximum
corrosion resistance, the surface of the stainless
steel must be kept clean and free of all of these
contaminants.

Note: Please follow the recommendations for
stainless steel cleaning products from your
preferred marine retailer.

Painting your tabs and actuators with marine

antifouling paint will discourage marine algae or
growth from adhering to these surfaces.

• Please follow the recommendations for stainless
steel antifouling paint from your preferred marine
retailer.

• When applying paint to the actuators, be sure
that they are in the fully retracted position. Do
not paint the stainless-steel ram above the area
that is exposed when retracted.

• Do not paint under the anode or the anode itself.

Sacrificial anodes for your Lenco stainless steel
trim tabs

Be aware that stray currents in your marina or in a
visiting marina can cause damage to your trim tab
blades if not protected by sacrificial anodes.

• The addition of anodes on each tab will deter
electrolysis.

• Do not paint under the anode or the anode itself.

• Check Anode condition frequently. Clean and
replace as needed.

Electrolysis is not a manufacturing defect and is
not warrantable

For more information on electrolysis, please visit
lencomarine.com and go to the troubleshooting
section.

Visual inspection of system

• Periodically inspect all wires, mounting brackets,
and hardware for damage.

• Make sure all mounting brackets and hardware
are secure and working properly.

• Periodically test system for smooth operation
