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
upward.
