Pretest
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
or it is inaccurate, return the product to your place of purchase.
Figure 2-6: E66062 (P58) Multisensor Transducer
Mounting Location
For the best performance, the transducer must be in contact with aeration-free
and turbulence-free water. Mount the transducer 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.
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 transducer where the boat may be supported
during trailering, launching, hauling, or storage.
• Single drive boat—Mount the transducer on the starboard side at least
75mm (3") beyond the swing radius of the propeller (see Figure 2-7 ).
• Twin drive boat—Mount the transducer between the drives.
