Because current diagrams place it in the propeller-shaft bearing stack, bearing condition matters directly to lower-unit service quality. This is a practical service inference supported by its documented location in the gear housing assembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstall 15841 only after confirming the correct Mercury or Mariner lower-unit diagram for the unit being serviced. Current parts diagrams show it in the counter-rotation propshaft housing with adjacent thrust and adapter components, so it should be matched to the exact lower-unit assembly during reassembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCurrent sources reviewed show \u003cstrong\u003e15841\u003c\/strong\u003e as the active OEM reference for this roller bearing.
