PSS Shaft Seal Maintenance Kit 1 1/8" Shaft 1 3/4" Tube

The PSS Shaft Seal Maintenance Kit 1 1/8" Shaft 1 3/4" Tube is a complete replacement and service solution designed for marine propulsion systems that rely on PSS bellows seals. Shaft seals below the waterline are critical to preventing water intrusion into the engine compartment, making regular inspection and timely maintenance essential for any vessel owner. This kit provides all necessary components to restore seal integrity and extend the operational life of your marine drive shaft system.

PSS bellows are engineered from specialized elastomeric materials that naturally degrade over time when exposed to saltwater, UV radiation, and mechanical stress. The maintenance kit includes replacement bellows and service components sized specifically for 1 1/8" shaft diameters with 1 3/4" tube dimensions, ensuring proper fit and hydraulic sealing action. Regular inspection every six months—and replacement every three to five years depending on usage conditions—prevents catastrophic water ingress that could damage engine bearings, seals, and internal components.

This maintenance kit is ideal for cruising sailboats, motor yachts, commercial fishing vessels, and any inboard propulsion system using PSS shaft seal technology. Installation requires basic mechanical skills and typical hand tools; detailed instructions are included to guide the process. Compatibility with your specific shaft assembly depends on exact bore and tube dimensions—verify your existing PSS seal specifications match the 1 1/8" shaft and 1 3/4" tube dimensions before ordering to ensure proper fit and watertight performance.
