Actuator & Tab Installation
Getting Started
• The actuator and tab installation must be done when the vessel is out of the
water. Do not attempt to install the actuators while the vessel is in the water as
the actuators and tabs are mounted below the water line.
• Before performing any electrical work on a vessel, disconnect the battery by
removing the positive (+) cable or if equipped, turn the battery disconnect
switch to the OFF position.
• Be sure to check for any obstructions: Before starting installation and drilling
any holes, verify that there are no mounting restrictions inside or outside the
transom. Choose a location about 3-4" from the chine (side of the hull). Hold
the tab up to the very bottom of the transom (1/8" from the hull bottom), and
hold the actuator on the trim tab. Then set the actuator upper hinge against the
transom. Verify this for both sides so that the actuators will not center on any
obstruction. If they do, reposition tabs slightly inboard or outboard.
