    Chapter 2: Installation 2.4 Transducer Cable Connections The transducer cable connector (and Y-connector, if supplied) has a nut that has been removed to aid installation. To allow you to complete the installation without cutting the cable, ensure that any holes you drill are large enough to accept the connector, with the nut removed (approximately 13/16"...
  • Page 46 Combined speed/temperature transducers have a 3 pin female connector that requires the use of an additional Y-shaped cable (Raymarine part number E66022) to attach to the 7 pin connector on the fishfinder. This Y-cable is included with your speed/tem- perature transducer.
  • Page 47 Chapter 2: Installation CAUTION: Do not cut the transducer cable or remove the connector. Do not try to shorten or splice the cable. If the cable is cut, it cannot be repaired. Cutting the cable will also void the warranty.
