ABSTRACT:
An outboard motor provided with a horizontally elongated marine propeller drive housing having a shaft journalled therein and a marine propeller mounted on the rear end of the shaft. A weed guard is mounted on said rear end of the housing and surrounds and encloses the propeller, the weed guard has a tubular section at its front end and attached to the housing, and the guard also includes a rearwardly and radially outwardly diverging tapered wall having a series of radially extending spokes which are relatively thin in circumferential direction as compared to their axial width. The guide also includes a cylindrical portion integrally connected with said tapered wall and disposed radially outwardly from and surrounding the propeller and extending rearwardly past the propeller. The cylindrical portion is perforated so as to be substantially open to permit the passage of water readily therethrough. The tubular section, the tapered wall and the cylindrical portion are integrally cast in a single piece, and a removable rear end plate is attached to the rear end of the cylindrical portion and extends across the cylindrical portion in a transverse direction. The end plate is formed by a series of concentric rings which define a series of arcuate slots circumferentially spaced around and between each adjacent pair of concentric rings.
