Look for the serial number on the hull or the hull member. It should be located on the transom, above the waterline. It may also be printed on a small plate.
The serial number is part of the hull identification number (HIN) on your boat. It consists of the manufacturer ID code, the hull serial number and the date the boat was built. The first three letters are assigned by the U.S. Coast Guard, and they identify the manufacturer of the boat. The second set of numbers represents the unique hull number, and the last set represents the model and year of the boat. Locating the serial number on a boat is quite easy if you know where to look.
Locate the hull of the boat.
Check the starboard side of the hull if the boat has no transom. If your boat has more than one hull, check the outermost starboard side at the end of the hull. more

1980-1999
The success of the Johnson outboard and its variants; salt water (brass & bronze), canoe mount and even the very rare Model F inboard, was immediate and far reaching. Almost overnight the Johnson’s were producing more outboard motors than anyone else in the world and they worked hard to keep the lead. here
The Model A received an update in 1925 becoming the A-25 and also received a single cylinder brother the J-25 the same year. In 1926 a larger motor called the Model P and rated at 6 horsepower, was introduced. Each subsequent year more models and higher horsepower models were produced, outboarding having caught the publics fancy in a big way! Competition from rivals like Ole Evinrude’s second company Elto, Lockwood and the original Evinrude firm, created a swarm of advancements in technology & horsepower. Johnson lead the way with many new features in the late 1920’s; rotary valving, higher horsepower and, possibly their crowning achievement, the smooth alternate firing A and K models of 1930. (1929 was the first time the famous Sea Horse logo appeared!) here
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.
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. 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.
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. This gave the operator much greater maneuverability and a positive acting reverse for bringing the boat into the dock. While this feature had been used for some time by the European brand Penta, (the Johnson’s licensed it from them), Johnson was the first US company to popularize it. This feature met with immediate public acceptance and is still incorporated on many small outboards today. here
On later model Mercury engines, the serial number was located on the swivel bracket, as shown in the picture below. First, these would be on a metal tag and stamped with the numbers. Later, the numbers were printed on a vinyl tag. Unfortunately, you'll often find that the vinyl tag has washed out. If you can no longer read the number on the tag, you’ll want to find that freeze plug on the powerhead in order to identify the outboard. more
Over the years, manufacturers have changed where this information is located on an outboard. I'll try to be as complete as possible below, while keeping this reasonably simple.
Chrysler outboards work by a model number. There are 2 locations where you may find this number. Early Chrysler models stamped it on a metal plate and it was placed under the carburetors, inside the lower cowling, or pan. Later models used the same plate, but you'd find it on the side of the transom bracket. [links]
Johnson and Evinrude outboards both work with model numbers for identification. In most cases, the model number is located on either the transom or swivel bracket. It can usually be found on a either a metal plate on earlier models or a sticker on later models. Once they switched over to the tags, this was another number that often washed out and could no longer be read. In this case, the powerhead freeze plug can be located and will have the serial number. The serial number itself won't do you much good, but an authorized dealer can use the serial number to match the engine up with a model number again. more
