PSS Shaft Seal 1-⅛" Shaft 1-¾" Tube

The PSS Shaft Seal for 1-⅛" Shaft and 1-¾" Tube is an essential marine component designed to prevent water intrusion at the point where your propeller shaft exits the hull. This product is ideal for experienced boaters who understand the importance of reliable shaft seals in protecting their engine compartments from water damage.

Engineered with elastomeric bellows and a minimal-contact design, the PSS seal virtually eliminates shaft wear while maintaining a watertight seal under various operating conditions. This innovative design allows for dual-element construction with low-friction materials, adapting to normal shaft runout and thermal cycling, which results in fewer inspections and extended drydock intervals.

Boat owners and installers will appreciate the straightforward fit of this seal, which integrates directly into standard 1-¾" tube installations without modification. Proper installation requires draining the gear oil and careful shaft alignment, ensuring optimal performance for inboard, I/O, and twin-shaft vessels.
