Installing trim tabs may sound like a complicated process. Host John Greviskis tries to make installation simple by giving you easy to follow directions. Installing the Trim Tab and Actuator - Start by setting the hinge to the trim tab on the dead rise where it will be installed.
- Mark out the holes with a pencil where the screws will be placed (figure A).
- Remove the hinge and drill out the holes using a 3/16" drill bit. Drill perpendicular to the transom.
- Countersink each hole and fill with marine grade silicone sealant.
- Slide the tab into place, leaving it parallel with the bottom of the transom.
- Attach the actuator to the tab with two screws.
- Next, place the actuator against the transom and draw an outline around the base.
- Set the actuator down and tape the manufacturer's template on the transom, over the outline.
- Drill holes for the mounting hardware with a 3/16" drill bit (figure B).
- Drive in the number 12 screws into place with a screwdriver.
- Wrap the threads of the fittings with Teflon tape to keep parts from seizing to one another and attach to the actuator foot.
Installing the Hydraulic Pump Tip: Install the hydraulic pump in a place that will provide it shelter from the elements (figure C). - Attach the pump onto the fiberglass using four stainless steel, self-tapping screws.
- Run the hydraulic lines underneath the center console.
- Add Teflon tape to each fitting, and then connect to the hydraulic pump.
- Fill up the hydraulic pump with two quarts of hydraulic fluid.
- Install a set of rocker switches at the console (figure D). Most manufactures will provide a template for cutting out the holes needed for installation.
Tip: tape off the console with low contact adhesive tape before cutting. This will help keep the edges from chipping. - If your console is wood, seal the holes with epoxy before installing the rocker switches.
- Run the wires from the switches to the terminal block. Each wire should have a ring terminal (figure E) crimped into place and heat sealed before attaching. This will seal it from corrosion.
- Tie in the wiring coming from the hydraulic pump to make a complete connection.
