The Morse Marine Haddo is a water-lubricated cutless bearing designed for propeller shafts in demanding marine or industrial applications. The Haddo model E02900 is specifically sized for a 1.75-inch shaft diameter, with a 2.625-inch outside diameter and a 7-inch length.

Features and materials

High-quality construction: The bearing consists of a sturdy, corrosion-resistant naval brass outer shell that is bonded to a fluted, nitrile rubber lining. All materials meet U.S. Navy specifications.

Water lubrication: This self-lubricating design uses water to provide low-friction operation, which also makes it environmentally friendly by eliminating the need for oil or grease.

Abrasion resistance: The rubber liner is tough and durable, designed to resist damage from abrasive particles in the water. The fluted design allows water to flush away sand and grit, protecting the shaft.

Noise and vibration dampening: The resilient rubber lining reduces engine vibration and noise, contributing to a smoother, quieter ride.

Precision-machined: The brass shell is machined and polished for consistently accurate dimensions and concentricity, which ensures a precise fit during installation in a strut or stern-tube mount.
