Remove the deck mounting plate from the light base (4 Allen bolts).
Save the bolts and washers. Locate the mounting plate on the spot that
you want your light. Rotate the plate so that the arrows are pointing
forward and the length of the arrow is aligned parallel to the keel.
Mark the 4 mounting holes, starting with the hole marked "Front" on the
mounting plate. Mounting holes are in 90° increments. Drill 4 mounting
holes (1/4") and a centered cable clearance hole (3/4"). Put the
mounting gasket on the deck mount (or shaped plate, if used). Use
caulk or bedding compound to seal bolt and wire holes before deck
mount is attached to deck. The plates are keyed to each other and to
the light: Be sure the arrows are pointing in the correct direction. The
light will rotate 180° either way from the arrows.
