Damge could likely be on the raw water pump
, the engine itself (especially head
seal / head
warping) and also the exhaust
if it is a wet exhaust. If your engine is fresh water cooled with heat exchanger
and you were not running with high power and it still starts and runs, chances might be, that the engine itself is fine, but especially the exhaust may have suffered. Retorqueing the head screws of the engine might still be a preventive option.
