1978 Penn Yan electrical- calling OG’s

Looks like I have inherited an old fuse block with both positive positions for fuses and a built in terminal bar for the grounds?  I am not sure what I am looking at on the transom. Perhaps some older welding mat material with both positive and negative posts like a terminal bar instead of using crimp attachments?  Tell me what I am looking at on the transom.

Man your not kidding old school.

 

first pic- you got me? Would have to see where the blue and brown go to but almost looks like a newer fish finder power cord is on there? 
 

second pic- just a traditional old school fuse block in its brass and glass tube fuse glory.  Blue seas makes a great updated fuse block you can get with the grounds also on it 
 

third pic- makes a little more sense now seeing it like that, brown fuse block is just an overflow/additional fuse block because the other is full

 

fourth pic- just looks like a real old junction block. Nothing more than saving on wire. All the like color smaller wires just connect at the bigger wires to be ran out. My guess is if you follow the smaller wires it goes to some type of switch panel that incorporates those same glass tube fuses near the switch, my ‘91 Lowe has that

Don't over think it, I believe my 1984 PY had that same connector design, I think they used up old technology that was in their stock. At least it's easy to decipher & lots of more modern ways to remake it cheaply if you desire.

Rather simple as stated above.  Replace with this:   

if you want to otherwise just run it. If you do run it, replace the fuses and put a little dielectric grease on the contacts.

Dont really see anything out of the ordinary.  Obviously a bit old tech but easy to update.

One odd thing Ive noticed.. low amperage fuses say 1-2 amp blade type seem to blow easier than the glass tubes.
