Mounting location
To ensure the best performance, the sensor must be submerged in aeration-free and
turbulence-free water. Mount the sensor close to the centerline of the boat. On slower
heavier displacement hulls, positioning it farther from the centerline is acceptable.
Allow adequate space above the bracket for it to release and rotate the sensor up-
ward.
Height required at mounting location
Note 1: Do not mount the sensor in an area of turbulence or bubbles: near water in-
take or discharge openings; behind strakes, struts, fittings, or hull irregularities; behind
eroding paint (an indication of turbulence).
Note 2: Avoid mounting the sensor where the boat may be supported during trailering,
launching, hauling, and storage.
Note 3: For single drive boat, mount on the starboard side at least 75 mm (3") be-
yond the swing radius of the propeller.
