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.
4.6 Optional 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 consid-
ering the following:
Choose a place free from vibration.
Choose a mid-boat flat position. The sensor
does not have to be installed perfectly per-
pendicular. The sensor must not be dam-
aged in dry-docking operation.
Choose a place apart from equipment gen-
erating heat.
Choose a place in the forward direction
viewing from the drain hole, to allow for cir-
culation 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.

4.7 Optional Water
Temperature Sensor
Transom mount water temperature
sensor T-02MTB
Fix the cable at a convenient location on the
transom with the cable clamp.
When the cable is led through the transom
board, make a hole of approx. 17 mm in
diameter to pass the connector. After
passing the cable, seal the hole with a
sealing compound.
