Abstract

The present invention relates to a combination tool comprising a wrench-end portion and a jaw-end portion, said wrench-end portion and said jaw-end portion being connected by a neck, said wrench-end portion containing an aperture which is adapted for engagement with a nut and said jaw-end portion containing a tooth member and a lower lip member which cooperate to facilitate the removal of a propeller from a propeller shaft.

Claims

1. A combination tool to facilitate the removal of a propeller from a propeller shaft of a motorboat engine comprising a wrench-end portion and a prying-end means, said wrench-end portion and said prying-end means being connected by a neck portion, said wrench-end portion containing an aperture which is adapted for engagement with a nut disposed on the propeller shaft, said aperture lying in a different plane than said neck portion and said prying-end means containing an upper tooth member disposed on the end of the prying-end means and a lower lip member disposed intermediate the upper tooth member and the neck portion, said upper tooth member and said lower tooth member being joined by an intermediate member, said upper tooth member and said lower lip member disposed in the same plane and projecting in substantially the same direction from said intermediate member to form a mouth portion at said prying-end means, and said lower lip member having a continuous working surface which enables it to provide for sliding engagement with the propeller shaft, said upper tooth member and said lower lip member cooperating to facilitate said removal of the propeller from the propeller shaft.

2. The combination tool of claim 1, wherein the neck member is provided with a square-shaped aperture.

3. The combination tool of claim 2, wherein the wrench-end portion of the combination tool is canted from said neck portion and a web member is provided to connect the wrench-end portion to said neck member.

4. The combination tool of claim 1, wherein the wrench-end portion is provided with a flange member which contains a half-moon shape.

5. The combination tool of claim 1, wherein the prying-end portion opposite said tooth and lip member has a flange provided with a half-moon shape.

6. The combination tool of claim 1, wherein the prying-end portion is offset relative to the neck portion to facilitate engagement of the lower lip member with the propeller shaft during a prying operation.
