If memory serves me correct you have Phelon ignition.

You should be able to get the coils from www.oldmercs.com

You reuse the metal core and just change the coil itself.

Thank you kind sir!!

Jim Judkins has Phelon coils for a very good price. email oldoutboardjim@hotmail.com. Get condensors for this motor. I am working on a WG7 and have replaced the coils and condensors. Started on 2nd pull. Don't forget to change the water pump impeller.

Thanks, I always have to have mech projects and my outboards are next.After looking at some pics here, the 53 is a WG7 and my other one looks like a 55 WM7.The 53 has been in our family since I was a little kid. I still have the Merc Mark 15 coils I was gonna install a long time ago.I will givee that feller a shout real soon for coils etc. Thanks Chuck
