ABSTRACT:
A cage-type enclosure is provided for the lower end portions of the upstanding power leg of an outboard marine propulsion unit from which the propeller of the unit is journaled with the cage enclosing the propeller and thus protecting the latter from fouling by weeds and other underwater debris and also serving to prevent accidental injury due to body portions of persons disposed in the water adjacent the propulsion unit from coming in contact with the enclosed propeller. The cage is generally egg-shaped in horizontal plan, inverted U-shaped in vertical transverse section and fin-shaped in side elevation including a forwardly and upwardly curving forward end portion, a substantially vertical rear end portion and a horizontal upper portion. The cage includes clamp structure at its upper end for removable clamped support from the power leg of the associated outboard marine propulsion unit adjacent the cavitation plate thereof.
