Humco Marine Announces Johnson Cutless Stern Tube Filler

Humco Marine Products Inc., St. Louis, Mo., has recently announced a new product—the Johnson Cutless stern tube filler—to its inland marine customers.

The Johnson Cutless stern tube filler is an environmentally-friendly displacement medium from Duramax Marine that affords freeze damage protection structure for a vessel’s stern tube, propeller shaft and bearings when vessels are laid up during the winter.

Humco said the non-flammable, water-soluble stern tube filler is available in 5-gallon buckets. The tube filler is easy to apply and remove, and it’s biodegradable.

The tube filler was designed to remove water from stern tubes to prevent disruptive damage to rubber bearings and stern tubes caused by freezing water. A vessel’s stern tube is typically located on a water-submerged part of the hull, where the water can’t ordinarily be removed by gravity drainage.

Humco carries a full inventory of marine products. The company has been providing the finest quality products and customer service to the marine industry since 1966.
