i.
Based on the distance between the two
Aluminum Support Plates, determine if space
between support beams will require the
installation of the Short Spanner Plate (Item #2)
or the Long Spanner Plate (Item #3). For proper
installation, the two slots on both sides of the
selected spanner plate should align with at least
two holes on each of the Aluminum Support Plates
as shown.
j.
Secure the spanner plate in place by placing two
screws in each slot and align it with the holes in
the Aluminum Support Plate. Place one Lock
Washer (Item #7) on each 1” screw (Item #8). The
screws will pass through the spanner plate and
Aluminum Support Plate and into the floor of the
pontoon. Use a drill with a #3 Phillips Bit to tighten
the screws in place. Make sure all hardware is
secure.

(Item #6). Place one Flat Washer (Item #4) on
each bolt. Coat the threads of each bolt with
anti-seize.

through the pontoon support beam and the
Aluminum Support Plate. Place a Flat Washer
(Item #4) and Nylock Nut (Item #7) at the end of
each bolt and secure each using a ½” wrench and
ratchet fitted with a ½” socket as shown.
