I have a Bayliner capri 1952 with an inboard 3.0 mercruiser and Alpha 1 out drive. I just this past week replaced the head gasket because it was leaking from directly under the head! so i removed the head, had it milled and checked, ordered new gaskets both exhaust and head, reinstalled the head as per manual. Took the boat out and after a few hours it blew the head gasket again! WTF!
it sound like a Howitzer! I am trying to understand how this happened to a new head gasket that was properly installed! And I am desperatley seeking the help of a knowledgeable person to answer this for me. I am new here so the post may exist somewhere else i just didnt find it. I appreciate any and all help in advance,
