Abstract
Abstract An elongated outboard motor prop including a first forked end for embracingly engaging the front side of the lower end of the upstanding propeller shaft housing of an outboard motor and provided with strap means for releasably securing the propeller shaft housing in the first forked end of the prop. The second end of the prop has a mounting bracket oscillatably supported therefrom for swinging of the prop relative to the mounting bracket about an axis extending transversely of the second end of the prop. The mounting bracket is inturn oscillatably supported from a mounting plate for swinging about an axis relative to the latter disposed at right angles to the first mentioned axis and the mounting plate is provided with means for at least semipermanent securement to the rear transverse cross member of a trailer frame. This mounting of the prop enables the latter to be used as a prop in securing an associated outboard motor in a tilted position or to be swung to an out of the way position extending along and disposed behind the rear transverse frame member of the associated boat trailer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
In combination, a boat trailer for supporting a boat thereon and including a rear transverse member, an outboard drive propeller shaft housing support and stabilizer comprising an elongated support arm assembly including a first end adapted for removable securement to the lower end of an upstanding propeller shaft housing, a mount base generally centered on said transverse member intermediate its opposite ends, a mounting bracket oscillatably mounted on said mount base for swinging about a first generally horizontal axis extending transversely of said transverse member, and means pivotally securing the second end of said support arm assembly to said mounting bracket for oscillation relative thereto about a second axis extending transversely of said support arm second end.
Claim 2
Dependent Claim
117 words
In combination, a boat trailer for supporting a boat thereon and including a rear transverse member, an outboard drive propeller shaft housing support and stabilizer comprising an elongated support arm assembly including a first end adapted for removable securement to the lower end of an upstanding propeller shaft housing, a mount base generally centered on said transverse member intermediate its opposite ends, a mounting bracket oscillatably mounted on said mount base for swinging about a first generally horizontal axis extending transversely of said transverse member, and means pivotally securing the second end of said support arm assembly to said mounting bracket for oscillation relative thereto about a second axis extending transversely of said support arm second end.
Claim 3
Dependent Claim
24 words
The combination of claim 1 wherein the effective length of said support arm is less than one half the length of said transverse member.
Claim 4
Dependent Claim
27 words
The combination of claim 1 wherein said first end of said arm is forked and is adapted to seatingly receive said housing between the fork arms thereof.
Claim 5
Dependent Claim
25 words
The combination of claim 3 including means carried by said first end for removably securing said propeller housing in seated position between said fork arms.
Claim 6
Dependent Claim
38 words
The combination of claim 1 wherein said support arm assembly comprises a pair of elongated members secured together in side-by-side relation and whose ends at said first end of said support arm assembly diverge away from each other.
Claim 7
Dependent Claim
19 words
The combination of claim 5 wherein said elongated members and said second axis are disposed in the same plane.
Claim 8
Dependent Claim
136 words
In combination, a boat trailer for supporting a boat thereon and includIng a rear portion, an outboard drive propeller shaft housing support and stabilizer comprising an elongated support arm assembly including a first end adapted for removable securement to the lower end of an upstanding propeller shaft housing, means carried by a second end of said support arm assembly and said rear portion universally coupling said second end to the rear portion of said trailer for angular displacement of said arm assembly in all directions relative to said rear portion, whereby said arm assembly, when in use, may project rearwardly from said rear portion and be swung through a vertical plane and, when not in use, may be swung to and be secured in a retracted position closely adjacent rear portion extending transversely of said trailer.
Claim 9
Dependent Claim
136 words
In combination, a boat trailer for supporting a boat thereon and includIng a rear portion, an outboard drive propeller shaft housing support and stabilizer comprising an elongated support arm assembly including a first end adapted for removable securement to the lower end of an upstanding propeller shaft housing, means carried by a second end of said support arm assembly and said rear portion universally coupling said second end to the rear portion of said trailer for angular displacement of said arm assembly in all directions relative to said rear portion, whereby said arm assembly, when in use, may project rearwardly from said rear portion and be swung through a vertical plane and, when not in use, may be swung to and be secured in a retracted position closely adjacent rear portion extending transversely of said trailer.
Claim 10
Dependent Claim
27 words
The combination of claim 7 wherein said first end of said arm is forked and is adapted to seatingly receive said housing between the fork arms thereof.
Claim 11
Dependent Claim
25 words
The combination of claim 8 including means carried by said first end for removably securing said propeller housing in seated position between said fork arms.
Claim 12
Dependent Claim
38 words
The combination of claim 9 wherein said support arm assembly comprises a pair of elongated members secured together in side-by-side relation and whose ends at said first end of said support arm assembly diverge away from each other.
