Housing — Do not clamp tightly on the
wrenching flats, possibly causing the
housing to fracture.
Hull nut — HAND-TIGHTEN only. Do not
over tighten.
4 Remove any excess marine sealant on
the outside of the hull to ensure smooth
water flow over the sensor.
Warning
The O-rings must be intact and well
lubricated to make a watertight seal.
5 After the marine sealant cures, inspect
the O-rings on the insert (replace if
necessary) and lubricate them with the
silicone lubricant supplied.
Warning
Be sure the insert is fully inserted into the
housing, and the cap nut is screwed on
completely.
6 Slide the paddlewheel insert into the
housing with the arrow on the top point-
ing forward toward the bow.
Screw the cap nut several turns until
the threads are engaged. The arrow on
the top of the insert, the cable exit, and
the arrow on the lip will all be aligned.
Continue to tighten the cap nut.
Be careful not to rotate the housing and
disturb the sealant.
HAND-TIGHTEN only. Do not over tight-
en.
Warning
Always attach the safety wire to prevent
the insert from backing out in the unlikely
event that the cap nut fails or is screwed
on incorrectly.
7 Attach the safety wire to one eye in the
hull nut. Keeping the wire taut through-

out, lead the wire in a counter clockwise
direction and thread it through one eye
in the cap nut. Thread the wire through
the eye a second time. Then lead the
wire through the eye in the insert. Twist
the wire securely to itself.
8 Route the cable to the instrument being
careful not to tear the cable jacket when
passing it through the bulkhead(s) and
other parts of the boat. To reduce elec-
trical interference, separate the sensor
cable from other electrical wiring and
the engine.
Coil any excess cable and secure it in
place with zip-ties to prevent damage.
9 Connect the sensor to the instrument
as per diagram.
5.2.6 Checking for Leaks
Warning
DO NOT leave the boat in the water
unchecked for several days.
When the boat is placed in the water,
immediately check around the thru-hull
sensor for leaks. Note that very small leaks
may not be readily observed.
Do not leave the boat in the water for more
than  hours before checking it again. If
there is a small leak, there may be con-
siderable bilge water accumulation after
24 hours. If a leak is observed, repeat
'Bedding' and 'Installing' immediately
(see 5.2.5).
