PSS PRO Shaft Seal 3-1/2" Shaft & 5" Tube

The PSS PRO Shaft Seal 3-1/2" Shaft & 5" Tube is a crucial component for marine applications, designed to protect your propeller shaft from saltwater intrusion and wear. This product is ideal for both experienced boaters and those new to marine maintenance, ensuring your drive system remains dry and operational.

Engineered with a dual-component design, the PSS PRO features a 3-1/2" shaft sleeve that securely wraps around the propeller shaft, along with a 5" tube that mounts to the hull or stringers. Its labyrinth-style packing system effectively sheds water while minimizing friction and heat buildup, making it suitable for high-RPM applications. Constructed from stainless steel and marine-grade elastomers, this seal is resistant to corrosion from saltwater exposure.

This seal is particularly beneficial for anglers and recreational boaters operating 24 to 35-foot center consoles, cuddy cabins, or sportfishing rigs, where maintaining shaft integrity is essential for uninterrupted time on the water. Installation is straightforward for those familiar with basic marine maintenance, ensuring compatibility with various hull-to-drive configurations.
