Quicksilver O-Ring 30613 / 8M0214919 (5-Pack)
This 5-pack of genuine OEM O-rings covers the most practical reality of marine service: O-rings are a one-time-use seal, and having the right quantity on hand means you can complete a full job without waiting on a reorder. These are precision-molded to the exact compound, durometer, and dimensions specified for Mercury and MerCruiser assemblies — not generic O-rings that happen to be close in size. The original part number 30613 has been superseded to 8M0214919; both references are the same current OEM part.

- Current Part Number: 8M0214919

Common Applications
Use these O-rings wherever the Mercury or MerCruiser parts diagram specifies part number 30613 or 8M0214919. They appear across multiple engine and drive assemblies to seal fluid passages, housings, and fittings — always verify against your model’s current parts diagram, serial number, and assembly location before ordering.
When to Replace
Replace any time you disassemble a sealed joint and the existing O-ring shows signs of flattening, cracking, hardening, swelling, or surface contamination. Never reuse an O-ring that has been compressed in service — always install a fresh one on reassembly.
Installation Notes
Clean mating surfaces thoroughly before installation. Lightly lubricate the O-ring with the appropriate fluid (fuel-safe grease or the system fluid) to ease installation and prevent tearing. Follow the Mercury service manual for orientation and torque specifications on the surrounding hardware.

Parts Desk Insights
Best used during engine or drive service where the parts diagram calls for 30613 or 8M0214919. The 5-pack format is ideal for rebuild jobs where multiple O-rings of the same size are replaced in one service, or for keeping a working stock on hand. Always match by part number — O-rings that look identical can differ in compound and will fail prematurely in the wrong application. If you’re searching by the original number (30613), the current OEM replacement is 8M0214919 — both will get you the same part.
