There used to be a company in the Province of Ontario, called Sailor Marine i'm not sure if they still exist or not, but they bought up all the parts that Chrysler had when they shut down the marine div. I don't have any more info than that, but you might try and look them up. Other than that I don't know of anybody that might be able to help you
I was a former rep. for Chrysler Marine, and you might want to buy several of these coils if you can find them. They do have a problem of failing far too often.
