Hey guys quick question.I'm in the middle of a major rebuild on my 1991 twin 502 Fountain,see winter project in Q&A.I noticed today there is now Merchathode system on either motor.Did they not have this system developed yet.Or did some one remove mine for some reason.I know I had one on my 1995 Nordic.Any ideas??

Thanks Anthony

it came in my 1989 Scarab w/a 365 mag.I believe it was a opt on the manf part

I don't even see wires or anything for the system.I quess I don't need it since the boat will be in fresh water and on the trailer most of the time.I just thought it was on all Mercruiser engine packages.
