I have a 1978 Catalina 30, hull #978. The boat has been maintained, but given her age she needs some care. I am about to embark on a drive train overhaul.
Following a lot of research and listening to others, I am led to Moyer Marine. I ordered, and have read, Don's overhaul manual.
My inclination is to remove my engine and swap with a MMI exchange engine. All of what Don talks about in the manual makes sense to me, except for one thing: replacement of parts and reconditioning as part of the overhaul.
I worked on cars incessantly as a teenager. We would pull an engine (goo american V8) and rebuild it. This means we would automatically bore the cylinders, grind the crank, put in new pistons, rings, wrist pins, rod and main beasrings, camshaft and bushings, valves, and so on and so forth. Every bearing was replaced; every surfaced machined.
It doesn't seem that MMI does that; or rather, they measure everything and do obly if past a judgment point in the tolerance range. That doesn't make sense to me - I would think it is automatic.
Anybody have any points of view they would like to share?
