Abstract
Abstract A lock device for a marine outboard motor comprises a semicylindrical pipe. A pair of end members are affixed to the ends of a pipe in parallel spaced relation extending perpendicular to the axis of the pipe. A locking device releasably locks the end members to the U-shaped clamp arms affixed to a marine outboard motor in a manner whereby the pipe covers the heads of manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of a boat thereby preventing unscrewing of the screws and removal of the motor from the boat.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
A lock device for a marine outboard motor having substantially U-shaped clamp arms affixed thereto and accommodating the upper open sheet of the stern of a small boat therein, and manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of the boat, said lock device comprising a substantially semicylindrical pipe; a pair of end members affixed to the ends of the pipe in substantially parallel spaced relation extending substantially perpendicular to the axis of the pipe; and locking means for releasably locking the end members to the clamp arms in a manner whereby the pipe covers the heads of the manually operated screws thereby preventing unscrewing thereof and removal of the motor from the boat.
Claim 2
Dependent Claim
124 words
A lock device for a marine outboard motor having substantially U-shaped clamp arms affixed thereto and accommodating the upper open sheet of the stern of a small boat therein, and manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of the boat, said lock device comprising a substantially semicylindrical pipe; a pair of end members affixed to the ends of the pipe in substantially parallel spaced relation extending substantially perpendicular to the axis of the pipe; and locking means for releasably locking the end members to the clamp arms in a manner whereby the pipe covers the heads of the manually operated screws thereby preventing unscrewing thereof and removal of the motor from the boat.
