Could old ships receive quick prewar engine overhauls?

Could Britain or the United States quickly overhaul older ships' engines before the Second World War, or would the hulls also need major work?

Many could receive a fairly quick engine overhaul because their hulls were regularly maintained, though some accompanying hull work would be necessary.

Whether a quick overhaul was realistic depended on the condition and refit history of each ship. The Royal Navy and US Navy possessed enough hulls to rotate units through regular interwar maintenance. That practice left many older ships in reasonable structural condition even when their machinery needed attention. Limited hull repairs would still accompany an engine overhaul, but a total reconstruction was not automatically required.
