Installation of Sensors (option)

13.4.1

Speed/temperature sensors ST-02MSB, ST-02PSB

The speed/temperature sensors (ST-02MSB, ST-02PSB) are designed for thru-hull
mounting. Install them as shown in this section.
Mounting considerations
Select a suitable mounting location, considering the following:
• Select a location where the transducer will not be damaged in trailering, launching,
hauling, and storage.
• Select a mid-boat flat position. The sensor does not have to be installed perfectly per-
pendicular.
• Select a location in the forward direction viewing from the drain hole, to allow for cir-
culation of cooling water.
• Select a location away from water flow from keel, water discharge pipe, etc.
• Vibration at the location shall be minimal.
• Do not install fore of the transducer of a fish finder, to prevent disturbance (and loss of
performance) to the fish finder.
Mounting procedure
1. Dry-dock the boat.
2. Make a hole of approx. 51 mm diameter in the mounting location.
3. Unfasten the locknut and remove the sensor section.
4. Apply marine sealant to the flange of the sensor. The height of the coat should be
approx. 6 mm.
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 your boat and check for water leakage around the sensor.
