Parts Desk Insights: Best suited for gearcase oil changes on outboard and sterndrive applications. This is a high-turnover consumable ā technicians replace it every service interval alongside the gear lube to ensure a leak-free drain plug seal. Stocking multiples is recommended for busy service bays.
The Sierra Oil Drain Screw Gasket (47-4698) provides a reliable replacement seal for the gearcase drain or fill screw. This small but critical gasket prevents gear lube leaks at the drain plug, maintaining proper lubrication levels in the lower unit and protecting gearcase components from wear and water ingress.
Consult the Sierra application guide to confirm fitment for your engine make, model, and year before ordering.
