Preparing the Mounting Location
After determining the mounting location for the
transducer, follow the steps below to position and
mount the transducerbracket.
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
(Figure 13). Align the bracket horizontally, using
the level; make sure that the lower screw hole
protrusion 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 (Figure 14).
NOTE:Ifyouhavea flat-bottomedaluminumboat,some
additional adjustment may be needed to accommodate
therivetsonthebottomoftheboat(i.e.thegapmayneed

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. If your propeller
movescounter-clockwise(inforward,asyou'refacingthe
sternof theboat from behind),mount thetransduceron
the portside.
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 yourmarkis centered in theslot(Figure 15).
NOTE: The third hole should not be drilled until the
