Coil For 1977 Mercury 150 In-Line Six

[Blevins Gap Outdoors]

I have a 77 Mercury 150 hp in-line six that needs a ignition coil. I looked for a listing on iboats parts finder and was unable to find a listing for it. From what it looks like to me a 18-5186 works on many of the motors similar to the 150. Most of the in-lines that year like the 115 use that coil. Could any of you guys tell me if that is the correct coil.

Make sure it's the coil and not something else. Coils are the most reliable component. Swap the bad with another and see if the failure travels with the coil or stays put.

Check your serial number, but this should be it...

That is correct, it only has a single coil. The reason I need one is that it developed an arc in the coil housing.
