Thought I'd post an update. From what I've found, the
Raytheon transducers seem to be made by Airmar, and the transducers on my
boat are also Airmar. The problem is that I can't find any part numbers stamped on the transducers, although I see numbers on the
cables (depth
transducer wire has Airmar 03-0596 and speed has Airmar 05-0596). I'm not sure if they are compatible, but I cut the connectors off the ends tonight, and the wires are all the same color on both the Raytheon and
Navico units. I'm going to crimp some female spade connectors on the wire and throw
power to the ST-60 and see what happens.
