Outboard motor lower-unit lock

A lock for a boat motor comprising:

• a locking pin assembly, having
• a dowel receiving face with dowel receiving holes defined therein,
• a cylindrical section perpendicular and abutting the dowel receiving face,
• a conical section having narrow and wide ends, the wide end of the conical section abutting the cylindrical section at an end of the cylindrical section opposite from the dowel receiving face, and
• a pin at the narrow end of the conical section, the pin having a threaded section proximal to the narrow end and a smooth section distal to the narrow end;
• a cylindrical shaft, having
• a shaft side the length of the shaft,
• end faces at the ends of the shaft,
• an end face slot defined in at least on of the end faces,
• a threaded hole for receiving the pin,
• an interior plane defined in the shaft side around the threaded hole, whereby the narrow end of the conical section is flush with the interior plane when the pin is fully inserted into the threaded hole;
• and
• a key having
• an exterior face,
• a plurality of planar major sides, perpendicular to the exterior face,
• a plurality of edges, generally half the length of the major sides, proximal to the exterior face, the edges defined by the abutment of the major sides;
• a plurality of planar minor sides, generally half the length of the major sides, distal to the exterior face and centered next to the edges, the minor sides alternate, thereby connecting the major sides,
• an interior face perpendicular to the major and minor sides and parallel to the exterior face, and a plurality of dowels on the interior face, whereby the interior face is flush with the dowel receiving face when the dowels are inserted into the dowel receiving holes.
