Installation
CAUTION
: Measure and drill carefully, since the bracket is only
slightly adjustable.
CAUTION
: To prevent drilling too deeply, wrap masking tape
around the bit 22mm (7/8") from the point.
CAUTION: Fiberglass hull
—Minimize surface cracking by
running the drill in reverse until the gelcoat is penetrated.
NOTE
: If the adjustable paddlewheel assembly separates from
the bracket, refer to Figure 10 on page 4 to reassemble.
Preparation
1. Measure the transom angle of the hull at the selected mounting
location using an angle finder (Figure 2).
2. Insert the two nuts into the slots in the back of the bracket.
Install the #8 adjustment screws (Figure 3).
Do not tighten the screws at this time.
3. There are three possible cable exits in the back of the bracket:
left, center, and right (Figure 4). Choose the best cable exit for
your installation and route the cable through the notches in the
back of the bracket.
Mounting
CAUTION
: The bottom edge of the adjustable paddlewheel assem-
bly (not the bracket) must be flush with the bottom of the hull.
1. The hull surface must be free of any dust, oil, grease, or loose
paint. Clean the selected location with a weak solvent (alcohol).
2. At the selected location and FLUSH with the bottom of the hull,
stick the double-sided tape to the transom (Figure 1). Peel off
the remaining non-stick layer.
3. Holding a straight edge against the bottom of the hull, position
the sensor at the selected location (Figure 5).
The bottom
edge of the paddlewheel assembly (not the bracket) must
be flush with the bottom of the hull.
Press the bracket firmly
in place. Use additional double-sided tape if necessary.
4. Using a 5.4mm, #3, or 13/64" drill bit, drill the two mounting holes
perpendicular
to the transom. To prevent drilling too deeply, wrap
masking tape around the bit 13mm (1/2") from the point.
5. Apply marine sealant to the two, #10 x 1-1/4", mounting screws
to prevent water seeping into the transom. Screw the sensor to
the hull (Figure 3). Check again that the bottom edge of the
paddlewheel assembly (not the bracket) is flush with the bottom
of the hull. If necessary, slide the bracket up or down. Tighten
the screws.
Do not over tighten.
