Pretest Speed and Temperature Functions
Connect the multisensor to the instrument and spin the
paddlewheel. Check for a speed reading (and the approximate air
temperature if applicable). If there is no reading or it is inaccurate,
return the instrument to your place of purchase.
Mounting Location
To ensure the best performance, the sensor
must
be in contact
with aeration-free and turbulence-free water. Mount the sensor on
the transom as close to the centerline (keel) of the boat as
possible. On slower heavier displacement hulls, positioning it
farther from the centerline is acceptable.
Headroom
—Allow adequate space above the bracket for it to
release and rotate the sensor upward (see Figure 1).
Caution
: Do not mount 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, or 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 the sensor between the drives.
