Flush Mount

1. Remove the label from over the sensor unit’s socket (see Figure 3). Apply

removable thread locker to the two studs supplied. Screw the studs into the
underside of the sensor unit (part A).

2. 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 vehicle/boat. Mark the position of the two mounting holes and the center
hole for the cable.

3. 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.

4. Pass the sensor connector-end of the cable through the center of the gasket

and through the center mounting hole in the boat/vehicle.

5. Plug the cable firmly into the sensor unit.
6. Orient the gasket with the arrow facing in the same direction as the alignment tab

on the sensor unit. 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.

7. With the sensor’s alignment tab pointing forward and parallel to the centerline of

the boat/vehicle, push the studs through the mounting surface. Check to be
sure the gasket is tucked under the lip of the unit. From underneath the
mounting surface, slide a flat washer and lock washer onto each stud. Fasten
them with the thumb nuts. Hand tighten only. Do not over tighten.
