It is designed to seal against water intrusion and lubricant loss at the gear carrier, helping protect the internal gear set from corrosion and contamination in the harsh marine environment. Sierra builds this seal to meet or exceed the performance of the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts of the same quality standard used in this seal.\u003c\/p\u003e\u003cp\u003eEach unit is sold individually as a single carrier seal, finished in white with a round profile to match its mounting bore.
