I'm considering buying a 1986 Catalina 30 that had difficulty starting from a 'cold start' on a 90 degree day. The broker turned it over 3 times before it 'caught' and he thinks that maybe on the third time he had turned the ignition to what I believe is a glow plug setting. I have a friend who bought a boat that had similar starting issues and the engine lacked compression, leading to a nice new Beta, $15k later. I'd appreciate any thoughts you may have.
