I appreciate all of your input. I have learned much about the nuances of the A-4 powertrain. Feedback from the Catalina 30 forum and Moyer Marine also cite fouled prop or fuel starvation as primary culprits. The first thing that I am checking is the prop. Prior to this use, the boat had not moved from her slip in the Chesapeake in almost 4 weeks. Come to think of it, the bottom was a lot greener looking that it had been!
We will be on the boat again this weekend. Will let you know what we find. - r
