I am looking at buying a boat that has a 76 model Mercury 50 hp engine on it. The last time it was ran was in 2000. When attempts were made to start it in 2001 it wouldn't start. I checked for spark yesterday and had no fire. The engine turns freely when engaging starter but does not fire. How do I check to see if the coil pack, etc. is good? What should the cylinder compression be?
