1.5 Optional Water Temperature/Speed Sensors
Through-hull mount water temperature/speed sensor ST-02MSB,
ST-02PSB
Select a suitable mounting location considering the following:
• Select 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.
• Select a place apart from equipment generating heat.
• Select a place in the forward direction viewing from the drain hole, to allow for circulation
of cooling water.
• Select a place free from vibration.
