Re: Atomic 5411 diesel rebuild
The 5411 is raw-water cooled, so like all such engines is prone to internal corrosion, head gasket issues, and so on.
I'd suggest checking very carefully everything in the cooling path.
Also I'm a bit concerned about the idea of rebuilding a 5411, as the engine's biggest issue is obselescence, and unavailability of the marinised parts. At least the 5411 doesn't have as many of those, compared to the fresh water versions. The last time I bought a new raw water pump for my 5424, it cost $375.
The transmission can be troublesome and rebuilds now cost more than a new ZF.
Generally, an old, undersized, obselete diesel, the worst one in the range, with unknown hours in unknown condition seems like a strange choice.
