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.

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.
