Actuator & Tab Installation
Installing the Trim Tabs
If your set came with adjustable upper hinge actuators (BEA3000), follow the
“Installing the Trim Tabs” instructions in this section, until instructed to skip ahead.
Position the tab:
Using the backing plate, choose a location 3-4" from the chine
(see figure 1 on page 10). Maintain a minimum of 8" from the centerline of your
drive unit to the closest edge of the trim tab. Align the bottom of the backing plate
as per figure 2. The hole pattern on the backing plate should be closer to the
bottom edge of the backing plate.
• Mark the pilot holes using the backing plate as a template. Make sure the tabs
can be mounted in the same location on both sides.
Verify that there are no mounting restrictions inside or outside the transom.
• Drill the mounting plate holes, using a 5/32" drill bit.
