Pretest Speed & Temperature Functions
Connect the multisensor 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, return the
product to your place of purchase.
Mounting Location
CAUTION
: Do not mount in an area of turbulence or bubbles.
Near water intake or discharge openings
Behind strakes, struts, fittings, or hull irregularities
CAUTION
: Avoid mounting the sensor 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.
• Allow headroom space above the bracket for it to release and
rotate the sensor upward (see Figure 1).
• Mount the sensor as close to the centerline (keel) of the boat as
possible to ensure the transducer’s face remains in the water
when the boat is turning.
•
Single drive boat
—Mount at least 75mm (3") beyond the
swing radius of the propeller (see Figure 2). The starboard side
where the propeller blades are moving downward is preferred.
•
Twin drive boat
—Mount the sensor between the drives.

WARNING
:
Always wear safety goggles and a dust
mask
when installing to avoid personal injury.
CAUTION
:
Never use solvents
. Cleaners, fuel,
sealants, paint, and other products may contain strong
solvents, such as acetone, which attack many
plastics, greatly reducing their strength.
IMPORTANT
:
Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
