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

Pretest Temperature & Speed Functions
Check for the approximate air temperature and a speed reading (if
applicable). Connect the sensor to the instrument and spin the
paddlewheel. If there is no reading or it is inaccurate, return the
product to your place of purchase.
Mounting Location
For 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.
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 1).
•
Twin drive boat
—Mount the sensor between the drives.
