TOR Marine Stuffy Box EVO propeller shaft seal 1,75″

The TOR Marine Stuffy Box Ø1,75″ EVO is a water-lubricated propeller shaft seal for inboard engines with a water-lubricated shaft system. This EVO version features an integrated nipple for forced water lubrication and automatic venting, which allows the seal to self-maintain and prevents dry running. It is a durable, flexible alternative to traditional grease-lubricated stuffing boxes and standard Volvo Penta seals, suitable for a 1,75″ propeller shaft and a 65 mm stern tube.

Key features and benefits:

Prevents water leakage and dry running: Automatic venting via integrated water nipple.
Water-lubricated system: Ensures constant lubrication and cooling, even at low speeds or when reversing.
Low-maintenance: Only requires annual lubrication with shaft grease.
Flexible NBR bellows: Absorbs vibrations and minor radial play.
Designed for Ø1,75″ propeller shaft: Fits a 65 mm stern tube.
Durable design: Preventive replacement recommended every 4–5 years or after 500 operating hours.
