Claim 10

In combination with an outboard motor of the type including a depending support portion provided with a horizontally elongated marine propeller drive housing at its lower end portion, said depending support portion being positioned between forwardly and rearwardly projecting portions of the housing, said housing including a front-to-rear extend-ing shaft journaled therein having a marine propeller mounted on its rear end, a weed guard comprising a hollow generally horizontal truncated cone-shaped body provided with axially and circumferentially spaced water passages formed therethrough, said body being constructed of lightweight, stiff but somewhat flexible material, the minor diameter end of said body including an integral endwise outwardly projecting cylindrical extension snugly telescoped over the rearwardly projecting portion of said housing closely forward of said propeller, and clamp means clamping said extension about said housing with the center axis of said body at least generally coinciding with the center axis of said housing and the major diameter end of said body loosely enclosing said marine propeller, said body including an integral radially inwardly projecting circumferentiallly extending annular portion at its minor diameter end portion, said cylindrical extension being integral with the inner periphery of said annular portion, said body being defined by a plurality of first graduated size and axially spaced circular band portions interconnecting with a plurality of second integral elongated circumferentially spaced band portions extending along the slant height of said cone-shaped body, said water passages being defined between pairs of adjacent interconnecting first and second band portions, said cylindrical extension including a full length longitudinal slot disposed along a radial plane of the center axis guard and extending into and through said annular portion, at least the circular band portion closest to said annular portion being interrupted between a first pair of adjacent second band portions between which said radial plane extends.

Claim 11

The combination of claim 8 wherein the circular band portion second from said annular portion is also inter-rupted between said first pair of adjacent second band portions.

Claim 12

In combination with an outboard motor of the type including a depending support portion provided with a horizontally elongated marine propeller drive housing at its lower end portion, said depending support portion being positioned between forwardly and rearwardly projecting portions of the housing, said housing including a front-to-rear extend-ing shaft journaled therein having a marine propeller mounted on its rear end, a weed guard comprising a hollow generally horizontal truncated cone-shaped body provided with axially and circumferentially spaced water passages formed therethrough, said body being constructed of lightweight, stiff but some-what flexible material, the minor diameter end of said body including an integral endwise outwardly projecting cylindrical extension snugly telescoped over the rearwardly projecting portion of said housing closely forward of said propeller, and clamp means clamping said extension about said housing with the center axis of said body at least generally coinciding with the center axis of said housing and the major diameter end of said body loosely enclosing said marine propeller, said cylindrical extension being provided with a full length longitudinal slot therethrough extending generally along a radial plane of said extension, said extension being circum-ferentially continuous from one side of said slot to the other side thereof.
