Abstract
A cutter assembly includes cutting blades spaced equidistant around a motor housing cover. The blades' cutting edges are orthogonal to a plane rotated around a housing centerline axis. Each cutting blade is ninety degrees from its adjacent cutting blades with respect to the housing centerline axis, and forty-five degrees from an axis orthogonal to the housing centerline. An embodiment includes a hinged cylindrical cover blade base locking around the housing for existing motor housings. Each cutting blade provides a forward oriented surface having a convex portion, an aft oriented surface having a convex portion, and a tip end. An embodiment provides a cutting blade tip end angle with respect to a housing centerline axis equal to the motor propeller blade pitch with respect to the same axis.
