[C320-list] Running engine with seacock off?

[Joe Luciano]

You didn’t mention engine temperature when you realized it and turned the water back on.  That would be a key measure.  I would certainly pull the cover on the raw water pump and see what the impeller looks like.  That would be a key area of damage from running dry.  If your engine temp didn’t get too high, you may be fine……
