Install the O-ring without twisting, pinching, or excessive stretching. Use only the lubricant, sealant, and assembly procedure specified for the exact application. For bearing-carrier installations, follow the applicable gearcase service procedure and inspect surrounding seals while the carrier is removed.\u003c\/p\u003e\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs this O-ring limited to one engine family?\u003c\/strong\u003e\u003cbr\u003eNo. It appears in several unrelated Mercury Marine assemblies, so the serial-specific parts diagram is the correct fitment reference.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be identified by size or appearance?\u003c\/strong\u003e\u003cbr\u003eNo. Similar-looking Mercury seals can have different dimensions and applications.
