11. After the sealant cures, inspect and lubricate the O-rings on the
paddle wheel insert with silicone grease or petroleum jelly (see
Figure 2-10 ).
12. Slide the paddle wheel insert into the valve assembly with the
arrow on the top pointing forward until it is fully seated (the insert
fits one way only).
Take care not to rotate the outer housing and disturb the sealant.
13. Slide the center ring of the safety chain onto the cable. Slide the
retaining pin in place and reattach the safety ring (Figure 2-9 ).
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.
14. Wrap one end of the safety wire tightly around the stem of the
housing and twist it together with the long end. Lead the wire
straight up and through one eye in the cap nut, then through one of
the safety rings. Loop the wire through the pull ring and twist it
securely to itself.
15. Route the cable to the transducer, being careful not to tear the
cable jacket when passing it through the bulkhead(s) and other
parts of the boat.
16. Attach the connector nut to the cable per instructions in Trans-
ducer Cable Connections on page 39.
17. Attach the assembled connector cable to the transducer.
18. Route the other end of the cable to the fishfinder, being careful not
to tear the cable jacket when passing it through the bulkhead(s)
and other parts of the boat. To reduce electrical interference, sep-
arate the transducer cable from other electrical wiring and the
engine.
19. Coil any excess cable and secure it in place using tie-wraps to pre-
vent damage.
