I am looking at the powerhead of my Mariner while running. Water is coming out from under the spark plug, top cylinder. This head looks odd to me. There seems to be two gaskets. The images on Ishop marine parts list really do not show a head only a cover and gasket. Is this powerhead / head one peice? I do not know the model # but the Ser# is 0A943983. Check out the parts diagram on Ishop, where is the head?
