Cleaners, fuel, paint, sealants, and other products may
contain strong solvents, such as acetone, which attack
many plastics greatly reducing their strength.

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 or it is inaccurate, return the
product to your place of purchase.
Mounting Location
For the best performance, the multisensor
must
be in contact with
aeration-free and turbulence-free water. Mount the multisensor 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 space above the bracket for it to release and
rotate the multisensor 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 multisensor 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 multisensor between the drives.
