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 dam-
aged in dry-docking operation.

• Select a place in forward direction viewing from the drain hole
for cooling water.
• Select a place free from vibration.
