Thru-hull mount water temperature sensor T-02MSB, T-03MSB
When selecting a mounting location for the sensor keep in mind the following points:
• Select a mid-boat flat position.
• The sensor does not have to be installed perfectly perpendicular, however it must not
be located where it won't be damaged when the boat is dry docked.
• Select a place apart from equipment generating heat.
• Select a place in the forward direction viewing from the drain hole, to allow for circula-
tion of cooling water.
• Select a place free from vibration.

Sensor
Cable
1. Drill a hole of φ21 mm in the hull.
2. Pass the sensor cable through the hull.
3. Pass the rubber gasket, washer and lock
nut onto the cable in that order.
4. Apply high-grade sealant to the sensor
flange, sensor and lock nut. Tighten the
lock nut. Do not overtighten it; torque
should be less than 59N•m.
5. Launch the boat and check for water
leakage around the sensor.
