Switched coils/wires?

[OldCoyote]

1975 Evinrude 20HP. I’m wondering if it matters which of the two coils fires which cylinder? If I switched the terminals feeding the coils should it make any difference to starting and running? I’m trying to identify a problem and thinking if it’s one of the coils this would help.

I am not an expert, but I have been watching videos about testing for spark and I have seen examples of where they did change out the coils for testing. As long as your feed wires match the cylinders you are testing.

You can test.----But motor cannot run with wires switched.
