It is designed as a direct replacement for OMC\/Evinrude Johnson part number 302497, making it a straightforward swap when the original grommet on your outboard has hardened, cracked, or gone missing during a rebuild or routine maintenance. Grommets like this one are used to seal small openings and protect wiring, fasteners, or fittings from water intrusion, so keeping this component in good condition helps preserve the integrity of the surrounding assembly.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-3329 measures 0.39 x 0.39 x 0.39 inches and weighs 0.01 pounds, making it a compact, precision-machined component sold as an individual piece.
