Description
Lower unit gear lube drain and fill hole screw and seal 79953Q04 is used with 3/8-16 drain/fill hole screw on all MerCruiser sterndrives, Mercury and Mariner outboards except the Verado series. It is very important to use the seal to make sure the drain/fill hole screw seats properly to retain the gear lube in the gear case and keep damage causing water out of the gear case.
