What is the recommended procedure(s) for assessing damage and coping
with salt water gaining access for a few hours to the engine area which
is located amidships in the upper bilge area ?

The engine is a Universal M4-30 diesel, which is a marinized Kubota I'm
told, which had/has oil in it.

I am uncertain to what extent this occurred as I paid the marina for
hurricane preparation [I was in the hospital at the time] which
specifically included screwing in the sump drain plug located in the
lower keel, which they didn't do, I have belatedly learned.

The storm surge was above the sump drain outlet but precisely how much
above I've yet to determine. I'm told it was mercifully brief, i.e. a
matter of hours. So, at this point, I'm uncertain as to the salt water
level in the engine compartment or for exactly how long.

Appreciatively,
