Default 502 Mag Mpi Life Expectancy

How long will these engines last with good service history? I am looking at a boat with 850+ hours showing on the hour meter. The seller does not know ecm hours. Should I go into this purchase knowing the engine will need to be completely refreshed sooner rather than later even if it runs fine and doesn’t excessively consume oil? I’m working on trying to have a shop do a leak down but I may have to make do with a compression test when I go look at it.

Should have some good life left if properly maintained however boating is expensive anyway you look at it.
