Mounting Tab Location
Available mounting area:
Before selecting a mounting location verify proper clearances inside (transom mounted compo-
nents, etc) and outside (turning drive and propeller clearance) of the boat. Do not mount tabs
in the chine area.
NOTE: The farther the tabs are between each other the better, this will allow you to achieve
the maximum performance out of your tabs.

Transition of the hull to tabs:
Recommended Transtion:
Allows tab to be removed fully from the water flow underneath the boat while under way.
Some applications may require the tab to be mounted even higher to be out of the water flow.

Using the template:
Once the location is determined use the supplied template for drilling holes.
The template is 15" by 19", scale is 1:1. Please note, you might need to visit your
nearest office supply store to have this large scale template printed correctly. Do not try
printing this on any size paper smaller than 15"x19". It is very important it is printed to scale.
Please contact [email protected]m if you would like this template mailed to you.
Example of the 950 Mercury bolt pattern
Depending on your tab model, if equipped with an electric sensor, only drill one hole for the
wire access thru the transom.
NOTE: PORT AND STARBOARD TEMPLATES ARE DIFFERENT

Installing the pumps and hydraulic lines:
Select the location to mount the hydraulic pumps.
NOTE: Keep pumps as level as possible.
Once mounted, route the hydraulic lines from the tab to the pump. Make sure hydraulic lines
are routed and secured away from any moving components in the boat..
Mount the tab:
If the Livorsi Trim Tabs are replacing existing tabs, make sure to seal any unnecessary holes on the
transom. Use a high quality marine sealer suitable for underwater use.
Recommended sealant: Marine Grade RTV / silicone sealant 4200 or 5200.
Use this same sealer and apply liberally around each fastener, indicator wires and between transom
and upper trim plate. It is recommended to apply the same sealant to the inside of the boat.
You may want to apply a piece of tape to the ends of the hydraulic thru hull fittings to prevent debris
from entering the openings.
If equipped with the electronic sensor carefully feed the sensor wires thru the transom.
Secure all mounting hardware.

Sensor Wiring
The sensor wire leads that were fished thru the transom will need to be inserted in to the 6 pin
Deutsch connector and secured with a wedge lock. Below is the pin out.
Pin Number Wire Color Description
1Red PPS1 (5V)
2White PPS2 (5V)
3Blue PPS1 Signal
4Black PPS1 Ground
5Green PPS2 Ground
6 Tan PPS2 Signal
Once pins are pushed thru the connector,
insert the wedge lock to secure pins.
The “arm” of the wedge lock should face the
same side as the connector clasp.

Testing:
The hydraulic system will be full of air, the system is designed to self purge this air when the tabs
are raised and lowered.
Purging Air
Before testing the system ensure the pump is filled with oil to the MAX level line.
To purge, fully raise and fully lower the tabs 3X times.
Check the oil level and inspect all hydraulic components for leaks.
Repeat fully raising and fully lowering of the tabs until operation is smooth.
NOTE: While purging the oil will foam (inducing air), allow to sit for 24 hours, fill as needed.
Fill the pump with oil:
The pump reservoir has markers indicating the
maximum and minimum oil levels.
The operating temperature and the oil used will
determine the reaction speed of the tabs.

Trim Tab Maintenance
Marine growth can interfere with proper operation of the trim tab planes and actuators. To reduce
problems due to marine growth, always return the trim tabs to the full "UP" position after operating
the boat and periodically inspect and clean marine growth from the actuators and planes.
The trim tabs are equipped with 5 zinc anodes to prevent galvanic corrosion. Galvanic corrosion is
the corrosion process occurring when different metals are submerged in an electrolyte. Sea water
is an electrolyte and submerged metal components must be properly protected. The anodes were
installed at the factory and will need to be changed when they are 75% of their original size.
