Stubby Pro Shaft Seals

Stubby Pro Shaft Seals provide boaters with a reliable and robust option compared to traditional mechanical face seals and lip seals.

Drawing inspiration from the success of the original SA Series Shaft Seals utilized in the commercial fishing fleets of New England, the Stubby Pro delivers the same advantages in a compact design that accommodates most stern tube configurations.

The Stubby Pro is engineered for low maintenance, featuring minimal failure points while enhancing performance and safety. If you have been boating for a considerable time, you have likely encountered a failure of a "packless" shaft seal or are aware of someone who has.

• No bellows to rip or lose compression
• No set screws to cut into the shaft
• No lip seals to tear
• No carbon stator to crack
• No stainless rotor to slip
• No flimsy hose barb to snap off
• No drips required to keep packing cool

Experience the difference and find out why many of the world’s finest boat builders, service yards, and marine mechanics trust RE Thomas’s shaft seals. Stop worrying about your dripless shaft seal and get the peace of mind you deserve.

The Problem With Modern Dripless Shaft Seals:
Experienced boaters have warned for years that modern dripless shaft seals can be dangerous and are more prone to catastrophic failure.

The Stubby Pro is designed specifically to address these concerns.

You see, space means everything in the design of modern boats. With the adaptation of smaller profile “dripless” shaft seals, boatbuilders and naval architects are able slide the engines further aft (not needing the extra room to change the packing on a traditional stuffing box).

This practice created an extra foot of “useable” space on some boats, but if the owner wanted to upgrade to a less complicated heavy-duty shaft seal, they can’t because they don’t have the room.

Enter the Stubby Pro Shaft Seal, short for “Stubby Profile”:
If you are experiencing issues with complicated dripless shaft seals, the Stubby Pro offers a reliable and efficient solution. Designed to combine the simplicity and reliability of a traditional stuffing box with the benefits of a dripless seal, the Stubby Pro is better than shaft seals featuring packless face seals and lip seals.

One of the key advantages of the Stubby Pro is its compact profile, allowing for installation in a wider variety of vessels that may have limited space. This means that boat owners who previously didn’t have the option of a more reliable shaft seal can now benefit from the Stubby Pro.

The Stubby Pro is water-fed to prevent starvation at higher speeds. This ensures that the packing material stays cool and prevents burning up and failure. Additionally, advancements in packing material technology have been incorporated into the design of the Stubby Pro. This allows for a watertight seal around the propeller shaft without excessive friction or heat generation.

R.E. Thomas’s shaft seals have earned the trust of many boat builders, service yards, and marine mechanics around the world. Upgrade your boat with a Stubby Pro.
