We just purchased a 1978 Catalina 27 with a gas atomic 4. The boat is in very good condition, and has been well maintained.
I've read through a number of threads in this section regarding the gas atomic 4. There's some real back and forth on this engine!
On the one hand, there were posts, such as one from a surveyor, who commented that the atomic 4 on boats he's seen scares the hell out of him. That's not real confidence inspiring for us! And, is the nickname for the engine, the atomic bomb? Isn't that just great
On the other hand, there are atomic 4 owners who say it's a simple, reliable engine. Though, they also recommend being careful to check for fumes -- turning on the blower and sniffing... and getting a fume sensor?
Well, we really like our boat, but we want, of course, to take appropriate safety measures. And, we'd like to have a realistic and balanced perspective. How risky is this engine? What is the appropriate perspective? What are the best practices regarding its use? Should we get a sensor? If so, what kind and where do we get one?
We plan to be diligent and follow best practices. And, now is the time for us to learn and begin to practice them. Thanks!
