Thanks JayzonAych. Yes the coils have the yellow epoxy in them. That is precisely why I never attempted to remove them from the base plate and laminations when I was testing them previously. SO Far…. They seem to be working fine. I have the original coils and condensers in the motor now and it runs pretty well in the barrel if it gets some throttle, but really struggles as it drops down toward idle and trolling. I had attributed the rough idle to the leaking fuel line and misadjustment on my part. But that sounds like it may not be the case. So the chamber that provides back pressure relief for idle, is that the outlet port that is molded into the bottom/rear/center of the lower pan? It seems to have exhaust and some water coming out of it at times.
I also included a shot of my complicated way of testing the water pump. I had tried to use my cordless drill but the motor’s drive shaft was too large to fit into the chuck. So I hauled the drill press out of the back of the garage( assuming that I would manage to dump water everywhere) and loaded the lower gearbox and water pump into the drill press. It was a difficult way to test, but it worked like a charm.
I didn’t get a chance to work on the Mercury tonight as I went for ride on my other perpetual project…. a1971 Honda CL450. Apparently I have a thing for machines that need a lot of TLC.
