Evinrude also made a nice Fisherman kit for the scout!
Muncie copied the Evinrude Scout design in 1938.
A BRIEF HISTORY OF THE NEPTUNE MIGHTY MITE OUTBOARD MOTOR
By Doug Penn
originally for AOMCI Knuckle Buster Chapter’s THE KNUCKLE KNEWS – Vol. 18, #4
In 1930 the Muncie Gear Works of Muncie Indiana, started building and marketing a 2 hp opposed twin
outboard motor. From this modest beginning came a line of outboard motors that spanned almost 60 years.
In 1938 they produced the first of what would, many years later, evolve into the popular Neptune Mighty Mite.
This little engine was a carbon copy of the Evinrude Scout motor that had sold so well the previous year. It
was designated as the 1A38 or 138A model, and was rated at 1.2 hp. The same motor was produced, almost
unchanged, as the 1A39 or 139A in 1939. In 1940 the horsepower and bore were increased to 1.5hp, with the
introduction of the 10A1, and the 11A1 in 1941. The 15A1 of 1945/46 was 1.5 hp as well.
This group of engines was the first of the MIGHTY MITE style motors. They are easily distinguished by their
spark plug, which was mounted on the starboard side of the cylinder head. With the exception of the piston
and cylinder bore, almost all the parts were interchangeable within this first group.
