Winter Rewiring

[Speedy]

Stripped all the old automotive wiring out and replaced with 12 gauge marine wire and connectors, new switch panel and dash, master battery disconnect +. All works well . BUT...when I checked out my transducer I discovered it had been repaired/epoxied. Question is might it be ok to after cleaning it, apply a thin coat of Marine sealant. OR...Throw it overboard. It works, but. Any suggestions?

Thanks,

Speedy
