PSS Shaft Seal 1" Shaft 2" Tube

The PSS Shaft Seal 1" Shaft 2" Tube is the marine-grade solution every serious boater relies on to eliminate water intrusion at the propeller shaft where it penetrates the hull. After years of running saltwater and freshwater vessels, any experienced angler knows that a failing shaft seal transforms a perfect day on the water into a costly emergency. This PSS design prevents bilge water contamination and maintains engine room integrity, protecting your boat's structural integrity and mechanical systems from the constant punishment of a working shaft.

The PSS Shaft Seal engineering uses a precisely matched carbon cuff and rotor assembly that creates a dynamic seal around your 1" diameter shaft within a standard 2" stern tube. The rotor diameter of 2.375" and carbon cuff diameter of 2" work in concert to accommodate shaft runout and minor misalignment without binding or leaking—critical when dealing with the vibration and flexing of a loaded fishing boat or cruiser under power. With a total compressed length of 6.225", this seal fits modern and retrofit installations seamlessly. The design eliminates the need for messy cutless bearing grease and the constant maintenance headaches that plague traditional rubber lip seals.

This seal is ideal for cruising sailboats, sportfishing vessels, and displacement-hull trawlers where dry bilges and reliability matter. Installation fits any 2" stern tube application and is compatible with both inboard diesel and gasoline engines. Whether you're upgrading an aging boat or building new, the PSS Shaft Seal 1" Shaft 2" Tube delivers the zero-leakage performance that keeps you fishing instead of bailing.
