I now own an '82 Wellcraft 18 Fisherman with a 2001 Johnson V4 outboard. It came with some melted and corroded wiring in the center console. Also looks like some wires were replaced without removing the old. The outboard is in good shape so I 'think' I would like to re-wire this boat and get it in great working condition (with the help of some friends of course) I cannot find a diagram online and the dealer says they have nothing older than 2007. Any help would be greatly appreciated.
