After alot of testing and talking to maint. guys we first tried the coil. No luck. Hated spending more $$$$$$$$$$$$$$ on parts that may or not be the problem. So called local evinrude dealer. He ran us thru what we already did and he said 100% sure its the power pack. So more $$$$ invested and guess what. It was the power pack. I could hug that darn thing. It was a real pain tracing this problem.
He said they always start with the power pack when testing fails to show a short. Good luck on your repairs.
