  • 1977 mercury 700 water pump

    hi all,
    cranked up the merc, finally running, and nothing coming out the tell tale. took the nipple end off and no water at all, but there was some gummy sticky stuff that reminded me of tree sap in the line.
    Any one know where i can find any type of schematic for the water pump?think i know where and how but a picture is worth a thousand.
