About: Martin Outboard Production

George Martin was an outboard racer and in 1946 he designed a radical new outboard motor using automotive-type poppet valves with the first production models introduced under the “Martin” name. These revolutionary new outboards with 2-stroke motor  “poppet valve intakes" were produced through an odd royalty based manufacturing agreement with the National Pressure Cooker Company of Eau Claire, Wisconsin (now National Presto Industries, Inc.)

Roughly 300,000 motors were made through 1954. Models included the 20, 40, 45, 60, 66, 75, 100 and 200. Each model number roughly translated to engine horsepower (e.g. 40 and 45 had 4.5 HP)

Martin outboards were a brand that had a lot of potential to be a major player in the outboard world but with stiff competition from OMC, Mercury and others, they closed up shop in the mid 50's

Martin outboards were manufactured from 1946 through 1954. They were very high quality and sported a number of innovative features, including the most important which was the mechanically actuated intake poppet valve

George Martin improved the reed valve concept by using mechanically actuated poppet valves that were timed to stay open longer and seal better than the simple flap on a reed valve. Activated by the engine crankshaft, the design was simple and allowed the motor to run much better at low and mid range speeds.
