Pretest
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(s) or it is inaccurate, check the connections
and repeat the test. If there is still no reading(s) or it is inaccurate,
return the product to your place of purchase.
Mounting Location
CAUTION
: Do not mount the sensor in line with or near water
intake or discharge openings or behind strakes, fittings, or hull
irregularities that may disturb the water flow.
CAUTION
: Do not mount the sensor in a location where the boat
may be supported during trailering, launching, hauling, or storage.
• For the best performance, the sensor must be in contact with
smooth water. To identify an area of clean water, observe the
water flow off the transom while the boat is underway.
• Mounting on the side of the transom where the propeller blades
are moving downward is preferred.
• Mount the sensor as close to the centerline (keel) of the boat as
possible to ensure the sensor remains in the water when the
boat is turning.
•
Single drive boat
—Mount at least 75mm (3") beyond the
swing radius of the propeller (Figure 1).
•
Twin drive boat
—Mount the sensor between the drives.
•
Stepped transom
—Mount the sensor on the step.
