You try swapping the coils around?
These coils can be bad but in all the years I've worked on these
motors, I've only found a couple to be bad.
The trigger has very thin wires that breaks under the shrink wrap at the connector, try gently tugging on the wire and see if it comes apart.
outboardignition.com has test procedures for your motor.
You'll be able to do basic tests with just an analog meter.
The more advanced tests will require a meter with a DVA or Peak Reading function.
Do the tests and get back, compression ok?
