What's this?

In the head of my HC 37 I'm challenging anyone to identify this electrical box! I suspect it to be left over from a mercerator but don't want to cut it out without knowin.https://photos.app.goo.gl/8hXzyUx4xuUyUHuX8

Nothing like it in my boat.

It appears to be a relay of some sort. Time to trace the wire and see where they go.

Maybe a control box for an Electroscan ? The Electroscan may not be there anymore.

I have seen every part of my 37c #52 and saw nothing like that. I removed every part of the electrosan and there was no fuse block like that. Are you going to try to repair your head or replace it?

I replaced the head a couple of years ago with a standard Jabsco one. I hadn't paid any attention to the electrical box.
