CAUTION! Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from any VHF radio antenna
cables or tachometer cables to reduce the possibility of interference. If the cable is
too short, extension cables are available to extend the transducer cable up to a total
of 50'. For assistance, contact the Customer Resource Center at humminbird.com
or call 1-800-633-1468 for more information.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough
slack in the cable for this movement. It is best to route the cable to the side of the
transducer so the transducer will not damage the cable during movement.
2a. If you are routing the cable over the transom of
the boat, secure the cable by attaching the
cable clamp to the transom, drilling 9/64"
diameter holes for #8 x 5/8" wood screws, then
skip directly to procedure 5, Connecting the
Cable.
or...
2b. If you will be routing the cable through a hole
in the transom, drill a 5/8" diameter hole
above the waterline. Route the cable through
this hole, then fill the hole with marine-grade
silicone sealant and proceed to the next step
immediately (see the illustration Routing the
Cable).
3. Place the escutcheon plate over the cable hole
and use it as a guide to mark the two
escutcheon plate mounting holes. Remove the
plate, drill two 9/64" diameter x 5/8" deep
holes, and then fill both holes with marine-
grade silicone sealant. Place the escutcheon
plate over the cable hole and attach with two
#8 x 5/8" wood screws.
