Furuno Ls4100 manual Optional Water Temperature/Speed Sensor, Mounting considerations

4.Position the second cable clamp halfway between the first clamp and the cable hole. Mark this mounting hole.

5.If a hole has been drilled in the transom, open the appropriate slot in the transom cable cover. Position the cover over the cable where it enters the hull. Mark the two mounting holes.

6.At each of the marked locations, use a 3 mm or 1/8” bit to drill a hole 10 mm (3/8”) deep. The prevent drilling too deeply, wrap masking tape around the bit 10 mm (3/8”) from the point.

7.Apply marine sealant to the threads of the #6 x 1/2” self-tapping screw to prevent water from seeping into the transom. If you have drilled a hole through the transom, apply marine sealant to the space around the cable where it passes through the transom.

8.Position the two cable clamps and fasten them in place. If used, push the cable cover over the cable and screw it in place.

9.Route the cable to the instrument being careful not to tear the cable jacket when passing it though the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the sensor cable from other electrical wiring and “noise” sources. Coil any excess cable and secure it in place with zip-ties to prevent damage.

4.6Optional Water Temperature/Speed Sensor

Water temperature/speed sensor ST-02MSB and ST-02PSB, which are designed for thru-hull mounting, are optionally available. Install them as shown below.

Mounting considerations

Choose a suitable mounting location considering the following:

Choose a place free from vibration.

Choose a mid-boat flat position. The sensor does not have to be installed perfectly perpendicular. The sensor must not be damaged in dry-docking operation.

Choose a place apart from equipment generating heat.

Choose a place in the forward direction viewing from the drain hole, to allow for circulation of cooling water.

1.Dry-dock the boat.

2.Make a hole of approx. 51 mm diameter in the mounting location.

3.Unfasten locknut and remove the sensor section.

4.Apply high-grade sealant to the flange of the sensor.

5.Pass the sensor casing through the hole.

6.Face the notch on the sensor toward boat’s bow and tighten the flange.

7.Set the sensor section to the sensor casing and tighten the locknut.

8.Launch the boat and check for water leakage around the sensor.
