PSS Shaft Seal 1″ Shaft 1-1/2″ Tube Review

Let’s Dive into PSS Shaft Seal 1″ Shaft 1-1/2″ Tube

The PSS Shaft Seal 1″ Shaft 1-1/2″ Tube isn’t exactly the kind of gear that gets your adrenaline pumping like a new rifle scope or a high-performance fishing reel. However, it’s absolutely critical for any boater who values a dry bilge and a reliable drivetrain. Manufactured by PSS Shaft Seal, this mechanical seal replaces the traditional stuffing box, promising a leak-free, maintenance-reducing alternative.

For years, I battled the constant drip, drip, drip of a traditional stuffing box. Replacing flax packing was a messy, time-consuming chore. The PSS Shaft Seal 1″ Shaft 1-1/2″ Tube offered the promise of a permanent solution.

Upon receiving the seal, I was immediately impressed by its solid construction. The stainless steel rotor felt robust, and the carbon flange seemed precisely machined. It appeared far more advanced than the simple, old-school packing gland it was designed to replace.

I considered several other shaft seal options before settling on the PSS Shaft Seal. The PSS Shaft Seal has a long-standing reputation for reliability and ease of installation. Competitors often lacked the same level of industry recognition and user testimonials. My first impression was positive; I felt confident that I had made a worthwhile investment.


Real-World Testing: Putting PSS Shaft Seal 1″ Shaft 1-1/2″ Tube to the Test

First Use Experience

The installation was straightforward, though I always triple-check anything below the waterline. I performed the installation in my driveway on a trailer. Once launched, I immediately observed the seal in action. Initially, there were a few drops as the carbon and stainless steel faces seated. After a brief engine run, the seal completely stopped leaking.

I tested the seal in a variety of conditions during my first several outings, from calm lakes to moderately choppy bays. It encountered everything from freshwater to saltwater. The seal performed flawlessly, even during extended periods of high-speed cruising.

The PSS Shaft Seal was remarkably easy to use. Unlike the old stuffing box, which required periodic tightening and adjustment, the PSS Shaft Seal required no intervention. It was truly a fit-and-forget solution.

There were no unpleasant surprises after the initial installation, just the satisfaction of a dry bilge.

Extended Use & Reliability

After a full season of use, the PSS Shaft Seal continued to perform flawlessly. I’ve now logged over 200 hours on the engine since installation, and the seal shows no signs of wear or degradation. There have been absolutely no leaks.

The only maintenance I performed was a visual inspection during my routine engine checks. There’s no need to tighten packing glands. The stainless steel and carbon components showed no signs of corrosion or erosion.

Compared to my previous experiences with traditional stuffing boxes, the PSS Shaft Seal is a game-changer. It’s a significant improvement in terms of reliability and reduced maintenance. I found the old stuffing box to require adjusting or dripping after every other use.

  • Total Length (A): 6.975″. This represents the overall length of the assembled seal.
  • Total Length (compressed) (Compressed A): 6.225″. This shows the length of the seal when the bellows are compressed during installation.
  • Rotor Diameter (B): 2.375″. This describes the diameter of the stainless steel rotor that rotates with the shaft.
  • Carbon Cuff Diameter (C): 2″. This indicates the diameter of the stationary carbon flange.
  • Stern Cuff Length (E): 1.5″. This details the length of the stern tube cuff.
  • The mechanical face seal created between the rotating stainless steel rotor and the stationary carbon flange is critical. This design eliminates the need for traditional packing and associated leaks.

These specifications are important because they ensure proper fitment and optimal performance. Incorrect dimensions could lead to leaks, premature wear, or even catastrophic failure of the drivetrain.
