I think we're going to need a few photos of what you have there. Is this an outboard or stern drive or? Please see link for terminology, Thanks. http://forums.iboats.com/mercruiser-...ml#post2545061
If it is a IO , then you would need a coil for a 12V marine application for the motor. A standard 12V step down to 9V coil would work on the motor. This should be the same for the 4 and 8 cylinder IO marine motors. JMO

it is an IO i will get some pics in a few min. my main question is putting a more standard coil in, auto maybe. mine does have the external resistor wire. with the points distributor. cant i do a conversion to get ride of the points or should i just try to get the mercury coil?
motor is not original to boat. the tag on the valve cover says it is model B181S. here are a few pics. I have lost fire and am trying to identify the ignition system i have so I can fix the issue. Does not have fire from coil.

The drive has a 3.0l label and it all looks original so I would think 3.0l is what it is. You can get a points kit. Napa carries most parts like that if you you want it fast or you could just buy it here on iboats.
