*There isn't a "blue wire" there are 2 diodes that can be clipped to open the bands and getting at them is not trivial.
Transmitting on a marine mf/hf frequency with an amateur transmitter is illegal except in an emergency.
Most marine radio comms are on ITU channels,*the vast majority of which are duplex channels so be prepared to do some serious knob twisting to program the channel splits on the 735 because*you can't turn a knob fast enough to*communicate with anyone otherwise. And don't expect an untrained*passenger to be able to use that radio to call for help if you can't.*
