  "title": "How Ole Evinrude Invented the Modern Portable Outboard Motor",
  "original_title": "Marine propulsion mechanism.",
  "summary": "A 1911 patent for a compact, detachable marine engine that allowed small boats to be powered by a portable, gasoline-driven propeller unit.",
  "what_it_does": "The patent describes a self-contained marine propulsion unit designed to be clamped onto the stern of a small rowboat. It integrates the gasoline engine, the vertical drive shaft, and the propeller into a single, portable assembly. By mounting the motor externally, it removes the need for heavy, permanent inboard engines, effectively turning a standard rowboat into a motorized vessel.",
  "what_it_does_not_cover": [
    "Does not cover electric outboard motors or battery-powered propulsion systems.",
    "Does not cover inboard engines where the motor is mounted inside the hull.",
    "Does not cover jet-drive propulsion systems that lack a traditional propeller."
