2. Preparing the Mounting Location
In this procedure, you will determine the mounting location
and drill two mounting holes, using the transducer
mounting bracket as a guide.
1. Make sure that the boat is level on the trailer, both
from port to starboard and from bow to stern, by
placing your level on the deck of the boat, first in one
direction, then in the other.
2. Hold the mounting bracket against the transom of
the boat in the location you have selected. Align the
bracket horizontally, using the level; make sure that
the lower corner of the bracket does not protrude
past the bottom of the hull, and there is at least 1/4"
clearance between the bottom of the bracket and
the bottom of the transom for fiberglass boats,
and 1/8" clearance for aluminum boats (see the
illustration
Boat Hull Types Require Different
Mounting Positions ).
NOTE: If you have a flat-bottomed aluminum boat, some
additional adjustment may be needed to accommodate the
rivets on the bottom of the boat (i.e. the gap may need to be a
little smaller than 1/8"). This will help you to avoid excessive
turbulence at high speeds.
NOTE: If your propeller moves clockwise (in forward, as you're
facing the stern of the boat from behind), mount the transducer
on the starboard side, and align the bottom right corner of the
mounting bracket with the bottom of the boat. If your propeller
moves counter-clockwise (in forward, as you're facing the stern
of the boat from behind), mount the transducer on the port
side, and align the bottom left corner of the mounting bracket
with the bottom of the boat.
3. Continue to hold the bracket on the transom of the
boat, and use a pencil or marker to mark where to drill
the two mounting holes. Mark the drill holes near the
top of each slot, making sure that your mark is
centered in the slot (see the illustration

Mounting Bracket to Mark the Initial Drill Holes ).
