Abstract
Abstract A marine craft outboard engine mount includes sideplate brackets which are wider at the top than at the bottom to permit "tucking" of the propeller under the transom. This provides a greater power-on thrust, giving a marine craft operator forward motion with a greater lift factor. Forward motion and the lift factor working simultaneously prevent the boat from "bogging down." With the engine mount, the engine sits in a higher position, and further behind the transom, which leads to increased performance.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
An engine mount for a marine craft outboard engine comprising first means for hooking over the transom of the marine craft, the first means including a first plate for mounting on the inboard side of the transom and for permitting vertical adjustment of the first means relative to the transom, engine support means, and means for movably mounting the engine support means on the first means, the engine support means including a second plate for mounting on the outboard side of the transom, the movable mounting means permitting engagement of the first and second plates with transoms having varying configurations, the engine support means further including a third plate for mounting the engine, the third plate being mounted stationarily relative to the second and extending at an angle to the second plate from a greater separation toward the top of the transom to a lesser separation toward the bottom of the transom.
Claim 2
Dependent Claim
152 words
An engine mount for a marine craft outboard engine comprising first means for hooking over the transom of the marine craft, the first means including a first plate for mounting on the inboard side of the transom and for permitting vertical adjustment of the first means relative to the transom, engine support means, and means for movably mounting the engine support means on the first means, the engine support means including a second plate for mounting on the outboard side of the transom, the movable mounting means permitting engagement of the first and second plates with transoms having varying configurations, the engine support means further including a third plate for mounting the engine, the third plate being mounted stationarily relative to the second and extending at an angle to the second plate from a greater separation toward the top of the transom to a lesser separation toward the bottom of the transom.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein the first and second plates and movable mounting means cooperate to clamp the transom between the first and second plates.
Claim 4
Dependent Claim
42 words
The apparatus of claim 1 wherein the first means further includes selectively adjustable means for jacking the first means and engine support means relative to the vertically upper edge of the transom selectively to position the engine vertically relative to the transom.
Claim 5
Dependent Claim
101 words
An engine mount for a marine craft outboard engine comprising first means for mounting over the vertically upper edge of the marine craft transom, second means for attachment to the first means, means for selectively movably mounting the second means relative to the first, and third means for mounting the engine, the third means including a pair of spaced supports extending generally rearwardly from the transom to define support edges remote from the transom, and a mounting extending between the support edges, the mounting including means for mounting the engine for tilting movement in a generally vertical plane behind the transom.
Claim 6
Dependent Claim
101 words
An engine mount for a marine craft outboard engine comprising first means for mounting over the vertically upper edge of the marine craft transom, second means for attachment to the first means, means for selectively movably mounting the second means relative to the first, and third means for mounting the engine, the third means including a pair of spaced supports extending generally rearwardly from the transom to define support edges remote from the transom, and a mounting extending between the support edges, the mounting including means for mounting the engine for tilting movement in a generally vertical plane behind the transom.
Claim 7
Dependent Claim
114 words
The apparatus of claim 4 wherein the first means comprises a first plate for mounting on the inboard side of the transom to extend generally parallel to the inboard side, the second means comprises a second plate for mounting on the outboard side of the transom, each of the plates including a generally vertically extending slot, a bolt extending through each said slot and the transom, and a nut threaded on the bolt to capture the first and second plates on the inboard and outboard sides of the transom, respectively, loosening of the nut permitting both plates to slide vertically on the transom selectively to raise and lower the engine relative to the transom.
Claim 8
Dependent Claim
28 words
The apparatus of claim 5 wherein the first means further includes means for jacking the first and second plates vertically relative to the upper edge of the transom.
Claim 9
Dependent Claim
31 words
The apparatus of claim 4 wherein the means for selectively movably mounting the second means relative to the first includes means for pivotally mounting the second means relative to the first.
Claim 10
Dependent Claim
98 words
The apparatus of claim 4 wherein the means for selectively movably mounting the second means relative to the first includes means providing a slot on one of the first and second means and means providing a pin on the other of the first and second means, the pin extending through the slot, and selectively movable in the slot, and including means for securing said one of said first and second means adjacent the slot to maintain the selected relative position of the pin in the slot to maintain the orientation of the second means relative to the first.
Claim 11
Dependent Claim
93 words
An engine mount for a marine craft outboard engine comprising first means for mounting over the vertically upper edge of the marine craft transom, second means for attachment to the first means, means for selectively movably attaching the second means from the first, and means for mounting the engine rearwardly of the second means, the engine mounting means including an engine carrier which permits tilting movement of the engine to position the axis of rotation of the engine propeller such that it points downwardly away from the transom and upwardly toward the transom.
Claim 12
Dependent Claim
93 words
An engine mount for a marine craft outboard engine comprising first means for mounting over the vertically upper edge of the marine craft transom, second means for attachment to the first means, means for selectively movably attaching the second means from the first, and means for mounting the engine rearwardly of the second means, the engine mounting means including an engine carrier which permits tilting movement of the engine to position the axis of rotation of the engine propeller such that it points downwardly away from the transom and upwardly toward the transom.
Claim 13
Dependent Claim
22 words
The apparatus of claim 9 wherein the engine mounting means includes means for supporting the engine carrier rearwardly from the second means.
Claim 14
Dependent Claim
42 words
The apparatus of claim 10 wherein the means for supporting the engine carrier rearwardly from the second means includes a bracket mounted on, and extending rearwardly from the second means, the bracket including a rearward portion upon which the carrier is located.
Claim 15
Dependent Claim
42 words
The apparatus of claim 11 including a pair of such brackets, the brackets extending generally transversely of the horizontal extent of the second means and transom along the second means and spaced apart generally longitudinally of the horizontal extend of the transom.
