Thanks for all the suggestions and ideas. I took her in to Holland Marine in Green Cove Springs this morning and we'll see what they come up with.
Donsan, although an excellent idea, mine are mounted to the stringers away from anything and are going to be as cool as the engine room allows.
The last set of regulators were installed in the fall and I have only run the boat less than 20 hrs. Unfortunately, I don't know what fried the last set of regulators. I also replaced the batteries, 4 4D AGMs.
For those that might be interested, I will let you know what we find or do.
This opinion is worth what you paid for it :)
