With the cooling system, the overboard water indicator doesnt mean the motor is cooling. It only means the pump is working. You should see a decent amount of spray from the upper exhaust housing relief hole even when the motor is cold. Not a huge amount, but more than just a dribble. That is an indicator that the water is actually circulating.
With the coil under the flywheel, Id buy a service manual if you plan to maintain the motor. If memory serves correct it should ohm out at 575 +/- 25. You have spark so I doubt that is the problem unless its a thin weak spark gapped at 1/2".
The rest is clockwork in terms of figuring out the problem.
