News Update !
Got new 'Ignition Module' installed !!!! Yippee!
Inspected old Module, and appeared to be rusted, pitted, with white-greenish corrosion on contacts. What a piece of JUNK Merc made for this part !
Basically, and open circuit board, with wires. Apply moisture, and you've got some real problems. New Module encased in Resin, so Merc must have know they had a problem with the original design.
Hoping this was the problem, and the fix, and can put this issue to sleep, once and for all ! Crossing my fingers, and saying a prayer.
Will test boat on water probably Thur.
