Patent abstract
A first portion or plug and a second portion or pencil are provided, for use in a device, such as a marine engine. The first portion or plug may have an outer surface with external threads and a cavity with internal threads. The external threads of the first portion or plug may be threaded oppositely from the internal threads inside the cavity of the first portion or plug. The opposite threading allows the plug and pencil combination to be detached and unscrewed from an engine without the plug and pencil coming apart.
