Two questions for the community: First, how do I fix this? the head unit is fine and I don't want to shell out for a new one. Replace the transducer or solder on a new plug?

Second, anybody had this before and what do you do to protect this weak link in the electronics chain?

Had a similar problem on my Mark 4, the brass poles are still good but the rubber plug has broken down....I big chunk of the rubber just fell away.

Try this:

Always connect your fishfinder first, then connect the battery.
When removing, disconnect your battery then your fishfinder.
Use dielectric grease on all connections, rinse with freshwater asap.
You never want power going to a open plug, that just opens it up for immediate
electrolysis.

If you follow these steps you will mitigate your corrosion problem.
