Flush Mounting on a Horizontal Surface
1. Remove the label from over the sensor’s socket (part A) (see Figure 4).
2. Apply
removable
thread locker to the two studs supplied. Screw the studs into
the underside of the sensor.
3. Using a torpedo level, check that the mounting surface is reasonably level. If
necessary, use shims to level the surface or choose another mounting location.
4. Using the gasket (part B) as a template, position it at the selected mounting location
upside down with the arrow facing forward and parallel to the centerline of the boat
.
Mark the position of the two mounting holes and the center cable hole.
5. Using a 3mm or 1/8" bit, drill the pilot holes. Using a 6mm or 1/4" bit, drill the two
mounting holes for the studs. Drill the cable hole with a 38mm or 1-1/2" hole saw.
Fiberglass
—Minimize surface cracking by running the drill in reverse until the
gelcoat is penetrated.
6. Pass the
instrument
connector-end of the cable through the center of the
gasket and down through the center mounting hole in the boat.
7. Plug the sensor connector firmly into the sensor’s socket.
8. Orient the gasket with the arrow facing in the same direction as the word
“FORWARD” on the sensor. Push the gasket onto the studs and slide it over the
connector.
NOTE
: The gasket fits one way only. A groove in the gasket fits over the
alignment tab on the connector.
9. With the word “FORWARD” pointing forward and parallel to the centerline of the
boat, push the studs through the mounting surface.
Check to be sure the gasket
is tucked under the lip of the sensor.
From underneath the mounting surface,
slide a flat washer and lock washer onto each stud. Fasten them with the thumb
nuts: metal side touching the washer.
Hand-tighten
only. Do not over tighten.
