Width, OMC Cobra, Mercury, Mercruiser Stern Drive","description":"\u003cp\u003eThe Sierra 18-7116 is a rubber O-ring seal sized for stern drive and outboard applications where a precise, leak-free seal is required. It measures 0.360 inches (9.1mm) inside diameter by 0.100 inches (2.5mm) width, and is molded in black rubber for resistance to marine fuels, oils, and water exposure. Each package contains one O-ring.\u003c\/p\u003e\u003cp\u003eThis O-ring is used as a component seal on the OMC Cobra oil indicator with washer assembly (1986-93, without cone clutch), and is also cross-compatible across a range of Chrysler\/Force, Johnson\/Evinrude, OMC, Mercruiser, Mercury, and Volvo stern drive and outboard applications that call for this size and profile of seal. It is built to meet or exceed the fit and performance of the original equipment part it replaces, making it a reliable choice for maintenance, rebuilds, or as a replacement when an old or hardened O-ring is leaking or failing to hold pressure.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
