Nine years ago I bought a dilapidated Catalina 30 with an Atomic 4, although the engine still ran with a bad rod barring and burned valve it was wasn’t something I would want on board in that shape. I did a DIY overhaul with Don’s help.
Nine years later the engine still runs smooth quiet and strong. Best of all I know the engine now and am not afraid to make any repairs and maintenance is a snap.
I’ve been told the A-4 is a “bad” engine, but that just doesn’t seem to be the case.
When a diesel is running it’s great, but when it goes wrong it’s more difficult and expensive to repair.
