Johnson outboard motors were first produced in 1922
Johnson Outboards was an American manufacturer of outboard motors founded by the four brothers Louis, Harry, Julius, and Clarence Johnson. 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. By 1908, they were making V4, V6, V8, and V12 aircraft and marine engines. In 1910, they built the first U.S. monoplane to exhibit their aircraft engines.
In 1912, their V-12 engine was making 180 hp, but disaster struck the factory in the form of torrential rain, flooding, and a direct hit from a tornado, which wiped out drawings, machinery, and everything else. The brothers relocated to South Bend, Indiana, and then Waukegan, Illinois. Starting in 1922, they designed and built Johnson Outboard Motors, a radical new, lightweight outboard made largely of aluminum.
In 1923, the Model 'J' was built, which was exactly half of the old Model 'A' motor wheel engine. This engine would eventually become the Utilimotor. In 1925, the P-30 was built, which was a race winner. By 1927, sales had exploded to the point that the South Bend plant could no longer accommodate the company, and a new factory was built in Waukegan, Illinois. By the mid-1920s, Johnson Outboards had surpassed Evinrude in sales and dominated the outboard racing scene.
In 1928, the Johnson Motor Company was the largest manufacturer of outboard motors in the world. They decided to start building their own boats and sell them as matched units with their motors. However, the Stock Market crash of the same year sent the world spinning into depression, and the Johnson Motor Company had to cut back on their operations. Despite these setbacks, the company continued to innovate and revolutionize the American outboard motor industry.
Today, Bombardier Recreational Products, a Canadian firm, owns the rights to Johnson Outboard Motors and provides support for existing motors through servicing and parts.

Johnson outboards were discontinued in June 2020
Johnson Outboards was an American manufacturer of outboard motors founded by brothers Louis, Harry, Julius, and Clarence Johnson. The company began building inboard 2-cycle marine engines in 1903 and, by 1908, they were making V4, V6, V8, and V12 aircraft and marine engines. In 1922, they designed and built Johnson Outboard Motors, a lightweight outboard made largely of aluminum. Johnson Outboards went on to dominate the outboard racing scene and held over two hundred patents.
However, in 1931, an over-ambitious marketing programme caused the company to go bankrupt. The Johnson Outboard Motor Company was then acquired by the Outboard Marine Corporation (OMC) in 1935. OMC itself filed for bankruptcy in 2000 and was acquired by Bombardier Recreational Products in 2001. Bombardier continued to sell outboards, but under the Evinrude Outboard Motors brand instead of Johnson. Finally, in June 2020, Bombardier discontinued the Evinrude Outboard Motors brand.
Despite the discontinuation of the Johnson brand, Bombardier continues to support existing Johnson outboard motors through servicing and parts. The company's rich history and innovation in the outboard motor industry have ensured its legacy, even after the discontinuation of its namesake brand.
While it is not clear when Johnson outboard motors added electric start functionality, the company was at the forefront of innovation in the outboard motor space for many decades. With their early start in 1903 and numerous patents, it is likely that they incorporated electric start technology as it became available and feasible for outboard motors.
The Johnson brothers' story began with a need for a motor to power their boat efficiently upstream. This led to the creation of a single-cylinder, two-cycle, 3-hp engine, which weighed a hefty 150 pounds. By 1905, they had significantly refined their design, reducing the weight to just 65 pounds while maintaining the same power output. This early success set the Johnson brothers on a path of innovation and success in the outboard motor industry, leaving a lasting impact even after the eventual discontinuation of the Johnson brand in June 2020.

Owners can convert older Johnson outboards to electric start
One key consideration is the starter mount, which must fit the engine perfectly. It is recommended to take detailed digital photos of the current motor and compare them to potential parts motors to ensure compatibility. The electric start kit should also include a rectifier to charge the battery when the engine is running at a decent rpm.
Additionally, it is worth noting that simply converting to electric start may not be sufficient. A charging kit is also necessary to keep the battery powered, and a comparable parts motor or bionic arm may be required for a complete solution. It is important to familiarise oneself with the electrical kit and all its components before beginning the conversion process.
For Johnson outboards with a geared flywheel, the conversion process may be more straightforward, requiring only the addition of a starter and the necessary wiring and cables. However, it is still important to carefully source the correct parts to ensure a successful conversion.
Overall, converting older Johnson outboards to electric start can be a rewarding project, but it requires careful planning, mechanical inclination, and the ability to source compatible parts. It is essential to weigh the costs and benefits before embarking on the conversion process.
