It is designed as a direct replacement for the factory seal on Mercruiser 1, R, MR, and Alpha model stern drives built through the 1974-97 range, restoring the seal that keeps water out and lubricating grease in around the drive shaft. Each unit is greasable, allowing fresh grease to be worked into the seal during service to extend its working life and protect against water intrusion at the gimbal\/drive shaft interface.\u003c\/p\u003e\u003cp\u003eThis part is packaged so that one 18-2094 seal and one 18-2100 seal are included together, since Mercruiser stern drive service on these units typically calls for replacing both seals as a set. The white-finished seal cross-references directly to Mercury Marine part numbers 30-60794A2, 30-60794A4, and 30-879194A02, so it drops into the same location as those OEM numbers without modification. It is a straightforward maintenance item for anyone performing gimbal bearing, drive shaft, or U-joint service on a compatible Mercruiser stern drive, and is commonly replaced any time the drive is disassembled for other repair work to ensure a fresh, reliable seal is in place.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

It cross-references directly to Mercury Marine numbers 30-60794A2, 30-60794A4, and 30-879194A02, so it installs in place of any of those factory

built to meet or exceed original equipment quality, cross-referenced to Mercury Marine OEM numbers 30-60794A2, 30-60794A4, and 30-879194A02 rather than being sold under the Mercury Marine brand itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace the 18-2094 seal?\u003c\/strong\u003e This seal is typically replaced whenever a compatible Mercruiser 1, R, MR or Alpha stern drive is disassembled for gimbal, drive shaft, or U-joint service, or when the existing seal shows wear that could let water in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need
