This factory piston ring set provides the compression and oil control rings required to restore proper cylinder sealing in Mercury 2-stroke outboard engines during engine rebuilds or overhaul — ensuring correct compression, preventing blow-by, controlling oil consumption, and restoring lost power and performance. Each set contains the rings for one cylinder. This is an authentic factory original part — never installed, never used.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCondition Details:\u003c\/strong\u003e This is a New Old Stock (NOS) part. The ring set itself is in new, uninstalled condition. As is common with NOS inventory, the original packaging may show signs of age, including shelf wear, dust, or minor cosmetic blemishes on the bag or box. The part is new and fully functional.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e⚠ Important: Piston rings are application-specific.
