Abstract
A propeller mount for deflecting ice away from the propeller of an icebreaker includes a wedge-shaped body, the front end of which is pointed, and the remainder of which flares rearwardly to direct ice outwardly away from the propeller assembly. By providing bubblers in the sides of the body near the front end thereof, outward deflection of ice by the mount is promoted. The rear of the body is also slightly wedge-shaped to provide a similr wedging action at the stern for steering ice away from propellers.
