The Tides Marine SureSeal® Shaft Seal System is designed to provide reliable, maintenance-friendly shaft sealing while minimizing water ingress and routine service requirements. Like all wear components, the lip seals require periodic inspection and replacement to maintain optimum performance and ensure the continued integrity of the shaft sealing system.
This article provides the manufacturer’s recommended procedures for replacing the Tides Marine lip seals installed on Ocean Alexander vessels. The information below is reproduced from the Tides Marine SureSeal® Installation and Service Manual and is intended to assist owners, captains, and qualified marine service technicians in performing this maintenance correctly and safely.
Before beginning any seal replacement procedure, ensure the vessel is properly secured, the propulsion system is shut down, and all applicable safety precautions have been observed. Follow each step of the manufacturer’s instructions carefully, and only use genuine Tides Marine replacement components to maintain proper sealing performance and preserve warranty coverage.
Important: Lip seal replacement should be performed only by qualified personnel familiar with marine propulsion systems. Improper installation or the use of non-approved replacement parts may result in seal failure, water ingress, drivetrain damage, and could affect manufacturer warranty coverage.
