Speed/Temperature Sensor (option) Installation
1.4.1
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
perpendicular.
• Select a location in the forward direction viewing from the drain hole, to allow for
circulation 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 diame-
ter 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.

Temperature sensors T-04MSB and T-04MTB
For installation instructions for T-04MSB and T-04MTB sensors, see the installation
instructions included with the sensor.
