I've purcased a 1981 Catalina 30 repowered with a BMW D-12, single cylinder 12hp diesel. BMW left the marine market in the '80s, and I'm trying to identify current parts sources. Can anyone help me? I want to lay in a basic supply of spare/maintenance parts and be able to replace major components as needed (engine's running fine now). I'd also appreciate any insights on the care/upkeep of these engines. I sail "Amity" out of Long Beach. Thanks! Mike Turner MTurner318@aol.com
