fuses?

[1975oday22]

i have a 1985 sunray with 3.0l omc engine. stern drive has been replaced . not sure with what. anyways. my wiring is a rats nest. and i am wondering. the fuse to my start key is getting hot. also there are no fuses except another one that is installed on a thick red wire to my panel of switches. am i to assume that i will need to redo all the wiring here? or can i buy a fuse block and go from there? if a pic is needed please let me know. thank you all in advance.

re wiring is up to you. Pictures will help. What value fuse is installed? Are you handy enough to re wire?

Since you re-wired a camper, I'm assuming you understand wire current capacity and fuse/circuit breaker requirements....
My '07 pontoon boat was a rats nest also even though I'm sure it is simpler than yours. I was surprised how the factory did it....
I can only say what I did.
Basically, the factory ran multiple power wires and ground wires all over the place to supply the switches and accessories. I installed separate power/ ground blocks which removed a lot of that wiring. This let me re-wire my switches with power/ground jumpers, like modern setups, with only one wire supplying power and ground to these switches and accessories. It let me add a battery master and stereo switch easily. My switches used resettable breakers so I stayed with that set-up. My hot feed has the inline fuse which worked fine, so I left it. I guess you need to re-evaluate yours as to wire size and load.
My gauges use a factory mercury harness plug-ins and the standard key switch power, so they were left as is.

My Toon rewire was pretty simple. I used a 9 space terminal block to connect console to boat.
