    Trim Tab screw

    1989 75hp Mariner.
    Serial # C204183
    Model # 70754129D
    I just got a Mercury trim tab #31640Q4 and it didn't come with the bolt. I know that the part number is 825427, but I'd rather pick up something at the hardware store, anybody know what size I need? Thanks for your help.

    7/16-14 x 1.250" (Stainless). Also need a stainless washer to go under the head of the bolt.
