Marine air was purchased by Dometic and still making Marine Air systems    [Only registered and activated users can see links Click here to register]   Unfortunately, they no longer service or have parts for older units such as yours. I am in the process of replacing my original AC (Marine Air) with a new Marine Air Turbo Vector system. BUT, my control board is still good. Take a photo of the top of you unit, the part number should be on the fan section someplace. If you hurry, I might be able to save my control board for you but would need to know your P/N, size etc to see if it is compatible. You can email it to me if you wish. Not sure if a 27yo AC is worth saving at this point.
