Step 1
Position the trim tabs against the transom and check to see that the upper
mounts of the hydraulic actuators do not center on an inside obstruction. If
they do, reposition tabs slightly outboard. The further outboard the tabs are
mounted, the greater the lateral (side-to-side) control. Position tabs 3" to 4"
from the chine and run towards the centerline of the boat.
Step 2
Attach the mounting plates and trim tab with ¼" stainless steel fasteners
along the bottom of the transom.
(See Figure 1)
Using the backing plate as a
template, mark screw hole locations. Assemble mounting plates and tab, dip
screws in marine epoxy before running in. Slide trim tab between backing
plate and hinge plate before running screws tight. Snug screws down to
secure mounting plates and trim tab to transom. If the transom is curved and
transom mount style tabs are being installed, a shim must be made of a suit-
able material to provide a flat mounting surface.
Step 3
Secure the lower hinge of each actuator to the tab with supplied machine
screws. Using a straightedge under the hull bottom, set the “negative
angle” of the tab’s trailing edge as shown.
(See Figure 2)
Step 4
Remove hex plugs from the upper mounts of the actuators.
With tabs set at negative angle, position the upper mounts
against the transom. Slide the actuator template behind upper
mount, align and tape to transom drill holes accurately as
indicated on templates. Drilling a small pilot hole first helps you
locate accurate centers.
Step 5
Apply Teflon tape on male threads of pipe nipples and tighten
into the actuator upper mounts.
Use care to avoid cross
threading and do not over tighten (Turn in nipple finger
tight, then two full turns with vise grips, NO MORE).
Apply waterproof sealant on surface around pipe nipples and
screw holes. Insert pipe nipples through transom and secure
actuator upper mounts to transom with 5/16" fasteners.
Note: cover the ends of the pipe nipples with masking
tape to prevent dirt
or debris from
entering the
system. Remove
masking tape
before making
connections
inside the
vessel.
