Ignition wiring plug corrosion

andyd

I went to start the boat in the slip and turned the key...NOTHING! No cranking, no chimes, no fuel pumps, no start, NADA. After a few days of diagnostics of everything I could possible check, I finally called in a pro who narrowed the problem to the engine harness wiring. After poking around the wiring under the instruments this is what we found. This plug shown below had obviously gotten wet over the years, causing corrosion. Problem solved, plug eliminated.

So everybody, check these plugs ASAP and look for the telltale green "verdigris" that would be evidence of corrosion.
