Installation Overview
Inside the boat there is often a channel or conduit used for other wiring, this can be used to
route cables. Be sure to route the cable as far as practical from the antenna cable of VHF radios
or tachometer cables to reduce the possibility of interference. The transducer and GPS receiver
cables should not be cut, and care should be used not to damage the cable insulation.
Basic installation tasks that you must perform include the following:
