Johnson Outboard Model From Serial Number

Johnson Outboards 1922 - The Beginning Years Johnson outboard motors made their public debut at the New York Boat Show in January 1922. International Dt466 Parts Manual more. It is unlikely that the Johnson brothers; Lou, Harry, Clarence and their brother-in-law Warren Conover, had any idea of the impact their little outboard would have on the world of boating. The Johnson brothers were cut from the same cloth as many of the great American engineers of the early part of the 20th century.

From relatively humble beginnings in Terre Haute Indiana, the Johnson’s became some of the premiere engineers of their day. The manufacturing of their small two cylinder outboard would not look very grand on their resumes when compared to building the first American monoplane, aircraft engines and record setting inboard speedboat engines, yet outboards would be their most lasting achievement. The small 2hp outboard that went on sale in 1922 had its roots in failure. After their aircraft and engine factory was destroyed in a storm, the brothers concentrated their efforts on a small two cylinder air-cooled motor that they adapted to be used as a helper engine on a bicycle. These Johnson Motor Wheels sold well for several years, but the economies of scale with which Henry Ford and others could produce automobiles rapidly eroded the market - after all, who would buy a motorized bicycle for the same cost as an automobile? Typical of the determination Americans had at the time, Lou Johnson was able to adapt some of the Motor Wheel’s engine to a new purpose; an outboard motor.

Nov 18, 2011 Bob at Snowman Marine in Edmonton provides his customers with help locating model numbers on their Evinrude & Johnson outboards. Someone will eventually ask you to identify your Johnson outboard. If you look about halfway down your Johnson's starboard side, you might see a metal plate with the serial number that contains code letters that identify it. That's great if your Johnson was created post-1980, but if that Johnson you operate.

Prior to 1969, Johnson model numbers were year-specific; serial numbers were used in identification. Johnsons from the 1969 to 1979 era use the last two digits of the year at the end of the model number to identify the model year; for example, a Johnson model number ending in '-4RL79' was built in 1979.

The water cooled 2 cylinder outboard would weigh in at only 35lbs, this was about ½ that of the typical cranky rowboat motors of the day. Six pre-production motors are believed to have been produced, full-fledged production began with serial number 507.

There can be no doubt that the Johnson’s hit a home run when sales for their little $140 outboard topped 3324 units their first year. Easy rope starting the Johnson Model A-25 Why was the Johnson's little outboard such a tremendous success? In addition to being lighter in weight, the Johnson Waterbug or Light Twin (Both names were used in the advertising) incorporated many features that we take for granted today but were revolutionary in 1922. A key component was the reliable flywheel magneto from the Quick Action Magneto Co of South Bend IN - later to become part of the Johnson company. Many outboards in 1922 used battery ignition and some still had large gear driven magnetos like the ones used on cars & tractors. The Johnsons Quick Action Magneto was small, compact and among the most reliable ever constructed. This magneto proved so good that the majority are still working 85 years later!

Another feature was the use of a rope to start the motor. Here again, Johnson set the trend over the competition who used “knucklebuster” knobs, leather straps or required the operator to wrestle the flywheel to start their outboards. (These were the days long before OSHA! Confirmit Manual. ) The rope start was simple, relatively safe (as long as you don’t whip someone with the cord!) and effective. There were a number of other novel features incorporated in the Johnson outboard; the easy to use and reliable carburetor with three settings; Choke, Fast & Slow. A simple piston waterpump to cool the motor was employed for many years.

And to keep the motor on the boat but still make it detachable in a jiffy, secure screw-type transom clamps were used. Ansi Geia Std 0009 Pdf Editor here. (Some outboards required you to bolt them on the transom!) The ability to tilt the motor up when beaching or in shallow water was also a rare on other outboards in 1922. While these features may be commonplace today, the Johnson brothers were the first to combine all of them. One of the most welcome and useful new features on the Waterbugs was the ability to turn (or swivel) the motor through a full 360 degrees.
