5 Installing

5.1 Display instrument

See Chapter 10 for the dimensions. Drill
the necessary holes in the instrument
panel or the bulkhead using the drilling
template supplied. Fix the display instru-
ment in place using the 4 threaded bolts
and nuts supplied. Make sure that the seal
is properly placed between the instrument
and the panel or bulkhead.

5.2 Sensor

CAUTION: NEVER USE SOLVENTS!
Cleaners, fuel, paint, sealants, and other
products may contain strong solvents,
such as acetone, which attack many plas-
tics greatly reducing their strength.
This sensor is should be installed in fibre-
glass or metal hulls only.
Never install this sensor in a wood hull
since swelling of the wood may over-
stress the plastic causing a fracture.
5.2.1 Fairing
Caution
Never use a fairing the protruding sen-
sor would be vulnerable to damage from
impact.
5.2.2 Pre-test
Connect the sensor to the instrument and
spin the paddlewheel.
Check for a speed reading and the approx-
imate air temperature.
If there are no readings or they are inaccu-
rate, check all the connections and repeat
the test. If there are still no readings or
they are inaccurate, return the product to
the place of purchase.

5.2.3 Antifouling Paint
Aquatic growth can accumulate rapidly
on the sensor's surface reducing perform-
ance within weeks. Surfaces exposed to
salt water must be coated with antifouling
paint. Use WATER-BASED antifouling paint
only.
Never use ketone-based paint, since
ketones can attack many plastics possibly
damaging the sensor.
It is easier to apply antifouling paint before
installation, but allow sufficient drying
time.
Reapply paint every 6 months or at the
beginning of each boating season. Paint
the following surfaces (see figure):
• Outside wall of
the insert below
the lower O-ring
(1)
• Paddlewheel cav-
ity (2)
• Paddlewheel ()
• Exposed end of
the insert (4)
• Exterior lip of the
housing (5)
• Bore of the hous-
ing up 0 mm (1-
1/4") (6)
• Blanking plug
below the lower
O-ring including
the exposed end

5.2.4 Mounting Location

• The water flowing across the hull must
be smooth with a minimum of bub-
bles and turbulence (especially at high
speeds).
Caution
DO NOT MOUNT near water intake or
discharge openings, or behind strakes,
fittings, or hull irregularities.
