I'm not sure if I'm kosher on this site since I'm not yet a Catalina owner but I'm looking to buy a 30 in the near future. The boat I'm looking at now is a 30 with a gasoline engine (I assume Atomic 4). I would prefer the diesel but the boat seems excellent and this is the only drawback I can see at this point. I'm interested in input from Catalina 30 owners regarding this. How concerned should I be with a gas vs. a diesel engine?While I'm at it...the boat will need a new prop. Any suggestions what I should get for it?Thanks.
