Only joking! But I am still amazed that a boat manufacturer doesn't have something so critically important to their product as a detailed diagram of the electrical system in each model.

The reason for knowing exactly where the transducer is located is that would allow me to find the wires that go to it and cut them. Sounds easy, but there are a lot of wires in that area. Most are either red or yellow, and, since the one size fits all schematic says that one transducer wire is red and the other is yellow, that provides zero clues, because on a boat, red is power and yellow is ground. There is no mention of a separate wire to send the signal back to the readout either,

And, of course, there are no wires going under the engine, so with my luck the wires are probably epoxied into the hull too.

Just disconnect the red or yellow wire on the back of the gauge. Only need to disconnect one to disable the transducer.
