I recently bought a 1996 23ft maxum with a 5.7 mercruiser ski inboard that has been sitting for a couple of years. I’ve addressed the fuel issues but after replacing the cap, spark plugs and coil wires, I’m still having intermittent spark issues. It usually starts up fine at the beginning of the day but if I kill it and restart it, it turns over but doesn’t have spark to any of the plugs. If I come back the next day it starts up then the same issue occures. It doesn’t have a kill switch and has proper battery voltage as well. I’m pretty new to the electronic system so if you could simplify it, that would be wonderful. Any help would be wonderful. Thanks ahead of time.
