I can't find any unit with that oval 5 pin plug. Boat was probably fitted out around early 2000's. Thanks,

  1. Based on the transducer, it’s an old hummingbird model. However, I wouldn’t even bother trying to find the old unit. Replacing it with something new will probably cost you less and put you 20 years ahead of what that old model could do.

    Considering there is a hummingbird on one of the pieces I’d guess it’s probably a Simrad
