Abstract
Abstract A new and improved protective cover for the lower portion of an outboard motor including the skeg, rudder and propeller shaft housing to increase the strength of the motor parts covered and protect such parts against water damage and wear. A reinforcing rib may be added for additional strength and an insert plate may be inserted in the cover to replace a missing skeg.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
An apparatus for protecting an outboard motor, which motor includes a skeg, a propeller shaft housing for a propeller shaft and a propeller, comprising: a. first cover member means for enclosing and covering a first portion of the outboard motor; b. second cover member means for enclosing and covering a second portion of the outboard motor; c. said first and second cover member means enclosing and covering the skeg and propeller shaft housing of the motor and each having a recess formed therein for passage of the propeller shaft for connection with the propeller, said first and second member means each comprising:
Claim 2
Independent Claim
102 words
An apparatus for protecting an outboard motor, which motor includes a skeg, a propeller shaft housing for a propeller shaft and a propeller, comprising: a. first cover member means for enclosing and covering a first portion of the outboard motor; b. second cover member means for enclosing and covering a second portion of the outboard motor; c. said first and second cover member means enclosing and covering the skeg and propeller shaft housing of the motor and each having a recess formed therein for passage of the propeller shaft for connection with the propeller, said first and second member means each comprising:
Claim 3
Dependent Claim
130 words
a lower cover portion for enclosing and covering the skeg; and 2. an intermediate cover portion for enclosing and covering the propeller shaft housing; 3. a rear collar formed on said intermediate cover portion adjacent said recess for forming an opening for passage of the propeller shaft therethrough wherein the propeller is external of said first and second cover member means; d. said first and second cover member means being formed from a solid member and in substantial conformity to the portions of the outboard motor enclosed and covered thereby for reducing impairment of the hydrodynamic flow characteristics of the outboard motor; and e. coupling means for connecting said first cover member means and said second cover member means together to enclose the covered portions of the outboard motor therein.
Claim 4
Dependent Claim
130 words
a lower cover portion for enclosing and covering the skeg; and 2. an intermediate cover portion for enclosing and covering the propeller shaft housing; 3. a rear collar formed on said intermediate cover portion adjacent said recess for forming an opening for passage of the propeller shaft therethrough wherein the propeller is external of said first and second cover member means; d. said first and second cover member means being formed from a solid member and in substantial conformity to the portions of the outboard motor enclosed and covered thereby for reducing impairment of the hydrodynamic flow characteristics of the outboard motor; and e. coupling means for connecting said first cover member means and said second cover member means together to enclose the covered portions of the outboard motor therein.
Claim 5
Dependent Claim
54 words
The structure of claim 1, wherein the skeg and propeller shaft housing of the outboard motor are formed at a lower end of cooling water inlet housing of the outboard motor and wherein each of said first and second cover member means comprises: an upper cover portion for covering the cooling water inlet housing.
Claim 6
Dependent Claim
41 words
The structure of claim 2, wherein at least one of said upper cover portion comprises: an upper cover plate having an opening formed therein adjacent the cooling water inlet for passage of water to the motor through said upper cover body.
Claim 7
Dependent Claim
41 words
The structure of claim 1, wherein at least one of said lower cover portions comprises: a lower cover plate having an opening formed therein adjacent an oil filler plug formed in the skeg to provide access to the oil filler plug.
Claim 8
Dependent Claim
40 words
The structure of claim 1, wherein the skeg of the motor has been damaged and is missing and further including: insert plate means mounted between said first and second cover member means for replacing the missing skeg on the motor.
Claim 9
Dependent Claim
38 words
The structure of claim 1, further including: reinforcing rib means mounted between said first and second cover member means at a position leading the covered portions of the motor for strengthening said first and second cover member means.
Claim 10
Dependent Claim
30 words
The apparatus of claim 1, wherein: each of said first cover member means and said second cover member means are formed having a stainless steel external surface for wear resistance.
