Nothing fancy, took these out last year and they need to go. I don't know much about them aside from they came out of a 1999 232 Cobalt. They worked when they came out of the boat so I'm assuming they still do. What you see is what you get (no senders)...
Be aware that the compass needs some sort of "brain" to work, Unless this is already in your boat it wont work. Feel free to ask questions. $25 buck plus the ride...

Bump....

Another bump... Somebody needs some gauges...
