What are these 2 wires?
 

I have 2 wires that seem to go into my outdrive Bravo 1 near the drive shaft and I dont know what they are. They are orange and brown. they have a round connector on the end for a screw terminal. If I had to guess they would get connected to a pos lead and ground becasue they were laying in the bilge under the mercathode thing with a pos and neg screw terminals. they are not for my drive trim or trim limit. that works fine.

Not sure what else to add but please help me.

mercathode has 4 wires to it terminals are color coded. I would think they go there. I would not connect them to pos and neg.

So what is the mercathode? could these wires be to help with corrosion and the anodes on my outdrive? FWIW there is nothing connected to my mercathode and I noticed this after my engine was pulled l;ast year to have a new transom assbly put in.

those wires are for your methocode ,the blue little box that should be mounted near your merc fuel/water seperator that says merthocode on it,my wires from my drive plug into a nother set of wires that run to that box,it is a system that prevents corosion from forming at your drive and also i think it deenergizes the water charge or something like that,but those wires go threw the outdrive hole into a black box at the rear bottom of your outdrive.
