The Waterman outboard engine appears to be the first gasoline-powered outboard offered for sale in significant numbers. [11] It was developed from 1903 in Grosse Ile, Michigan, with a patent application filed in 1905 [ 12 ] Starting in 1906, [ 13 ] [ 14 ] the company went on to make thousands of his "Porto-Motor" [ 15 ] units, [ 16 ] claiming ...
Mercury outboards 30 hp and below are manufactured by Tohatsu in Japan. [citation needed] Mercury developed a processor-enhanced line of outboards called the "Verado" outboard engine. [when?] [5] The "Verado" system integrates the outboard into an entire system, including "fly-by-wire" steering and advanced diagnostics. Verado engines are ...
1927 Johnson Seahorse outboard motor at the Tellus Science Museum. The original company that made Johnson inboard motors and outboard motors was the Johnson Brothers Motor Company of Terre Haute, Indiana, United States. They started building inboard 2-cycle marine engines in 1903 in a barn behind the house, along with matching boats.
Outboard Marine Corporation sometimes referred to as Outboard Motor Company was formed in 1929 when ELTO was merged with Lockwood-Ash Motor Company. They began using the name OMC in 1956. Outboard Marine Corporation was the world's largest manufacturer and supplier of outboard motors and second largest producer of powerboats.
Evinrude Outboard Motors was a North American company that built a major brand of two-stroke outboard motors for boats.

For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
Throughout the design phase of the KKM, Froede's engineering team had to solve problems such as repeated bearing seizures, the oil flow inside the engine, and the engine cooling. [19] The first fully functioning KKM engine, the KKM 125, weighing in at only 17 kg (37.5 lb) displaced 125 cm 3 and produced 26 PS (19 kW) at 11,000 rpm. [ 20 ]
