"Hi,
Not a direct I/O questio
"Hi,
Not a direct I/O question but I apprecaite getting some knowledge. On my 1990 Searay 27' Sundancer with twin 4.3s I have always seen a green insulated, about 18ga wire go down the inside transom and appeared to be screwed to the brass bilge garboard, drain plug fitting. I always assumed it was another ground system to fight galvanic corrosion.
Yesterday I was resealing all the transom below water fittings and found the drain plug fitting is no way attached to the ground wire?? When I removed the drain plug fitting I could see the ground was screwed into the fiberglass in the bilge just by the drain plug fitting, but in no way electrically connected to the drain plug fitting. I was surprised, I had always assumed the wire connected to the drain plug.
Now the dilema is do I assume Searay screwed up?? and should I connect the ground to the brass bilge drain plug fitting?
The boat has a Mercathode system and really no drive corrosion issues, so I kinda hate to fix something that doesn't seem broke.
Again Thanks for any advice."
