OK - I'm somewhat new to boating. I have a 15ft trihaul with a 1979 70hp johnson outboard. We replaced the coils since the wires appeared to be dry rotted. Fires right up runs strong and smooth. Stop to fish for an hour or so restarted fine. Moved to new location after a short ride (5 - 8 min.) fish for 15 - 20 min. and then it will not restart. I lift the choke and try starting but no go. Had to be toed in. Retry after some time and it starts right up. Compression good in all cylinders, water pumping with no issues - heads just warm to the touch - but the fly wheel is much warmer. Not sure if it is how I'm trying to start it or something else. Could this be a power pack issue? Any suggestions would be greatly appreciated. Boat runs great and idles perfect, just can't count on it restarting on the lake.
