Thanks very much for the reference to raymarine... I've printed the whole
thing out ( couldn't read the small print) and hope it helps. TVM

Well, this URL is for finding the original (Raytheon) transducer
wiring
diagram) at the connector end.

It looks like the wires that went to pins one and two of the connector
are
the depth reading part of the transducer. The two wires that went to those
pins are the ones you need to connect to the Humminbird.
Both of the instruments you mentioned are the so-called "dual
frequency" design. Humminbird uses a sort of freaky low frequency, but the
Raytheon uses an almost standard 200/50 Khz set of frequencies. The
Humminbird's 200/83 Khz set is probably close enough to work at least with
the 200 frequency. Which is not too bad for shallow water and smaller
fish.
Hey! Give it a try, all it can do is smoke!
