Quicksilver 10-79953Q04 Screw Kit

Quicksilver 79953Q04 Lower Unit Gear Lube Drain & Fill Hole Screw and Seal is a replacement drain/fill screw assembly designed for MerCruiser sterndrives and most Mercury and Mariner outboards equipped with 3/8-16 non-magnetic gear lube fill or vent screws. This non-magnetic screw and seal help maintain a secure seal in the lower unit, preventing gear lube leaks and protecting the gearcase from water intrusion.

Using the correct drain/fill screw and seal is essential during routine gear lube service. The included seal ensures the screw seats properly, helping retain lubricant while preventing water from entering the gearcase, which can lead to costly internal damage.
