Hello there! I'm new to this forum and have done a lot of reading and learned a whole lot, but can't seem to find exactly what I'm looking for. Hoping someone can help me out.
I have an older Mercury 650 Thunderbolt, 65 hp outboard (I think it's in the 70's). The serial # is 7020523 which doesn't seem to be recognized anywhere. Does anyone know what year this is?
Anyway, the problem I'm having is that the last time I went out, it was running great and then it dropped to about half power (maybe running on 2 cylinders) and was trying to get back to full power but didn't. It's done this before but always managed to fix itself.
I ran a container of Sea Foam cleaner through it and put in new plugs...same thing, ran great for awhile and then back down to half power. The next day when I tried to start it, it wouldn't start.
No spark. No power to the green wire on the CDI box. Is there anyway to jump power to the green wire to test it? The part number on the CDI box is 332-4796. Any other suggestions as to what the problem may be or should I write her a death certificate?
