Pre-test for Speed and Temperature
Connect the sensor to the instrument and spin the paddlewheel. Check
for a speed reading and the approximate air temperature. If there is no
reading, return the sensor to your place of purchase.
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 (see Figure 1).
Caution: Do not mount the sensor in an area of turbulence or bubbles:
Near water intake or discharge openings;
Behind strakes, struts, fittings, or hull irregularities;
Behind eroding paint (an indication of turbulence).
Caution: Avoid mounting the sensor where the boat may be supported
during trailering, launching, hauling, and storage.
• Single drive boat—Mount on the starboard side at least 75mm
(3”) beyond the swing radius of the propeller (see Figure 2).
• Twin drive boat—Mount between the drives.
