Well if the aftercoolers stay full of sea water when hauled out, that time counts as well. Although I wouldn't try to put that fine a point on it. Two things you can do to help: drain the aftercoolers after haul out or better still flush with fresh water and drain.

Make sure that you do a complete disassembly, cleaning of both air and water sides, reassembly with new gaskets and lots of grease followed by pressure testing.

Tony Athens discusses this for Cummins and Yanmar engines in Tony's Tips on Sbmar.com. Equally applicable to Cats.
