I have a 2005 Doral intrigue with twin merc 350 mpi horizons closed cooling system . I was looking for the sea strainers and could not find one for the mercs. The ac unit and generator both have their own. Is it possible there is no sea strainer for these engines . I followed the line coming in from the hull valve runs from the shut off valve under the engine to a y and goes right into to the water pump . Any idea ?
