The engine ran fine yesterday. Today I tried to start it and it is silent. Not a noise. The key turns and nothing. It is a late 70’s to early 80’s Johnson V4 Seahorse 100. At first I thought it might have been the key switch cause the key has been really difficult to turn for the last year. I went ahead and replaced it and nothing. Afterward I checked to see if it was even getting power. I know I should have done that first. It is NOT getting power to the control box at all. The battery is new, only started the boat maybe 6 times and is reading full charge 95-100%. There are two connections to both positive and negative and one goes to the motor and one to a couple bus terminals that simply power a 12v cigarette lighter. Which works fine. I traced the main wires to the engine and it seems that is as far as I have gotten. Like I said at the beginning, it worked fine yesterday and now nothing. When i put the key half turn into accessory, it doesn’t even turn on the lights. There is literally no power getting to the key switch at all. Is there a fuse that could have tripped? If so where would it be? If one of the power packs were bad would it stop electric flow to the key? I’m selling the boat and it needs to start! Any insight is appreciated. Thank you.

Look around the starter solenoid for a 20 amp fuse in a fuse holder.

No, the power packs do not have anything to do with it.
