MOUNTING THE MOTOR BOX
(Only after the wheel pulley is mounted)
· STANDARD PEDESTAL MOUNT (page 8): The Pedestal Bracket is designed to mount on most round (cylindrical)
p
edestals. It comes in two sizes (shallow bracket for spoke-to-pedestal clearances from 2-3/4ʺ to 3-3/4ʺ, and deep
bracket for spoke-to-pedestal clearances over 3-3/4ʺ).
· STANDARD PEDESTAL MOUNT WITH DROPDOWN PLATE (page 10): The dropdown plate lowers the motor
b
ox below the pedestal bracket so that bracket doesn’t hit the base of the pedestal.
· REVERSE-VERTICAL PEDESTAL MOUNT (page 12): If there is limited room below or aft of the wheel, a vertical
m
otor box is available that can be reverse-mounted forward of the wheel. The drive pulley faces forward instead of
aft; the motor rotation is reversed. The motor box may also be mounted with the drive pulley inside the perimeter of
the wheel if 1ʺ spacers are used between the spokes and the wheel pulley. Due to increased leverage on the pedestal
bracket, it may require screws for mounting instead of hose-clamps.
· L-BRACKET MOUNT (page 15): Mounting on a surface that is parallel to wheel shaft, such as a coaming, sidewall,
de
ck or cabin sole requires the L-bracket.
· BULKHEAD MOUNT (page 17): The motor box bracket by itself can be used with appropriate shims to mount the
m
otor box assembly directly onto a console or bulkhead parallel to the boat's wheel. Teak or marine-board shims are
used to align the drive belt with the wheel.
· TILTED WHEELS (page 19): The L-bracket is used to mount motor box on cockpit sole or cockpit side-wall for boats
w
ith tilted wheels or slanted gear-driven wheels.
· OVERSIZED WHEELS (page 19): The L-bracket is used to mount motor box to deck or sidewall in boats with large
w
heels, or “deck-sweeper” wheels.
Shim
Shims can be used to obtain proper belt alignment between drive pulley and wheel pulley.
