"I have a 25 hp mercury, fires
"I have a 25 hp mercury, fires on one cylinder(top). changed coils and switch box, thats what all the manuals say should be wrong. Nothing! So just by accident, I unhook top cylinder coil, and guess what? Bottom cylinder fires like crazy. So with both coils hooked up, top fires bottom dead. With one coil hooked up, that cylinder fires. HELP!!!!!"
