I am hoping someone has this diagram for the MS400 twin engine model. I have the diagram for the single, as well as the very basic layout diagram from the owners manual. TIA!
Well, I found the wiring diagrams I was looking for and I will upload them to the Library. They are the DC wiring diagrams for the Mainship 400 with twin Yanmars.
I found them in my owner's manual! (I never thought to look there)
