ATTACHING THE SENSOR
ASSEMBLY
The speed and temperature sen-
sor assembly attaches to either trans-
ducer as shown. Pinch, or squeeze,
together the tabs at the top of the sen-
sor and slide the assembly down into
the tracks on the back of the trans-
ducer. Push it down until it stops, and
then, push the tabs back, outward,
until the catches snap into the holes
on the transducer.
CAUTION - It is a good idea to
restrain the speed wheel from spinning
freely while trailering the boat. Damage may result because there is no
water to lubricate the wheel bearings. A rubber band works good for this.
IN-HULL MOUNTING
Finding the best location for the
transducers before mounting is criti-
cal. Choose a flat smooth spot near the
center of the bilge and near the back
of the boat. It is a good idea to make
a "test run" before you permanently
install each transducer. This makes sure that you can,
indeed, get a reading through your hull, and when the boat is on
plane. Put about a half inch of water in the bilge and hold the trans-
ducers in the intended location. Move the transducers around until
you get the best reading. Mark the spot.
Remove each transducer from its housing as shown in figure 8.
To install, clean the spot of mud and oil. Using an epoxy or silicone
glue, make a puddle about the same diameter as the transducer on
the hull. Place the transducer in the glue. Press it down firmly, gen-
tly twisting it back and forth, making sure that there are no air bub-
bles in the glue between the transducer and the hull. Let the glue
dry completely before turning the unit on.
