Maintenance and Refit
When does a marine engine need a rebuild, and what does it cost?
The decision should rest on the engine’s own data rather than on hours: cylinder balance, injector return flow, oil pressure and overheat history. A "time for a rebuild" verdict given without those measurements is a guess.
Why it works this way
Diagnostic reading frequently shows that a rebuild is not required — at which point the measurement has paid for itself many times over.
