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
vehicle/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 vehicle/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

vehicle/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.
