Sierra 18-0388 Power Trim Hose Connector Gasket, Replaces Mercury Marine 27-988231 and 27-98823, Pack of 2

The Sierra 18-0388 Power Trim Hose Connector Gasket seals the connection point on power trim hose fittings, preventing hydraulic fluid leaks at the connector joint. This gasket is sold as a pack of 2, so you have a spare on hand or enough to service both connector points in a single job. It is designed to replace Mercury Marine / Mercruiser 27-988231 and 27-98823 connector gaskets, making it a straightforward drop-in for anyone servicing an existing power trim hose connector rather than a new fitting design.

Because the power trim system relies on hydraulic pressure to raise and lower the outdrive, a worn or hardened gasket at the hose connector is a common source of slow trim operation or fluid seepage. Replacing this gasket restores a proper seal at the connector without needing to replace the entire hose or fitting assembly.
