PSS Shaft Seal Maintenance Kit 2" Shaft 3" Tube

The PSS Shaft Seal Maintenance Kit for 2" Shaft 3" Tube (Part No. 07-200-300R) is a comprehensive service and replacement solution designed for marine propulsion systems utilizing PSS bellows assemblies. This maintenance kit addresses the critical need for routine inspection and component replacement on below-waterline shaft seals, which are subject to continuous exposure to saltwater, chemical degradation, and mechanical wear over extended service intervals.

The kit includes replacement bellows, o-rings, and stainless steel set screws specified for the 2-inch shaft, 3-inch tube configuration. PSS engineering recommends bellows replacement on a six-year cycle or sooner if inspection reveals signs of aging, surface cracking, or chemical attack from fuel, oil, or biocides. During bellows replacement, simultaneous replacement of the o-ring seals and set screws in the rotor assembly prevents secondary failure and maximizes the service life of the complete seal assembly. The stainless steel components resist corrosion in harsh marine environments where standard steel components would deteriorate rapidly.

This maintenance kit is essential for commercial fishing fleets, offshore charter operations, and cruising sailors who maintain vessels with PSS shaft seal systems. Owners who operate in tropical waters, high-salinity environments, or undertake extended offshore passages should inspect bellows more frequently than the standard six-year interval. Proper maintenance of the shaft seal prevents catastrophic water intrusion, bearing damage, and potential engine room flooding—critical safety and financial concerns for any marine operation.

Packaged at 1.4 lbs, the kit contains all components required for a complete seal service on compatible PSS assemblies. Regular use of this maintenance kit as part of scheduled haul-out or dry-dock procedures extends system reliability and reduces the risk of unexpected failure at sea.
