What is the History of Johnson Outboards?

Johnson Outboards has a rich history dating back to the early 20th century. The company’s journey is intertwined with innovation, manufacturing excellence, and a dedication to providing reliable and high-performance outboard motors.

The story of Johnson Outboards began in 1907 when the founder, O.C. Johnson, designed and built a small, two-cylinder outboard motor in Wisconsin. This pioneering invention marked the beginning of a legacy that would shape the marine industry for decades to come.

Over the years, Johnson Outboards developed a range of groundbreaking innovations, including the introduction of the first electric start outboard motor in 1953 and the pioneering of the revolutionary “Sea-Horse” brand in 1947. This brand became synonymous with quality, reliability, and power, cementing Johnson’s position as a leading manufacturer of outboard motors.

In 1968, Johnson Outboards merged with Evinrude Motors to form Outboard Marine Corporation (OMC). Under OMC, the Johnson and Evinrude brands continued to thrive, offering a wide range of outboards for recreational and commercial applications. However, OMC faced financial difficulties in the 1990s and eventually filed for bankruptcy.

In 1991, the Johnson and Evinrude brands were acquired by Bombardier Recreational Products (BRP). Under BRP, the focus shifted towards developing advanced technology, such as four-stroke engines and electronic controls, while maintaining the heritage of quality and performance associated with the Johnson and Evinrude names.

Today, Johnson Outboards continue to be a trusted choice for boat owners worldwide, offering a legacy of innovation, durability, and exceptional performance. Whether you’re an experienced angler or a recreational boater, a genuine Johnson outboard is a reliable and valuable asset.

Is My Johnson Outboard Worth Anything?

The value of your Johnson outboard depends on several factors, including its model, condition, age, and rarity. Well-maintained and original Johnson outboards, particularly those from the classic era, can command significant value in the collector’s market.

Here are some factors that influence the value of a Johnson outboard:

• Model and Horsepower: Rarer models and higher horsepower outboards tend to be more valuable. For instance, a vintage Johnson 40-horsepower outboard might fetch a higher price than a more common 10-horsepower model.
• Condition: A well-maintained outboard in excellent condition with original parts will be worth more than a neglected or heavily modified engine. Look for signs of corrosion, damage, or missing components.
• Age and Rarity: Older outboards, especially those from the pre-war era or with limited production runs, can be more valuable than newer models due to their historical significance and rarity.
• Completeness: Outboards with all original parts, accessories, and documentation are more desirable and valuable.
• Restoration: A professionally restored outboard can command a higher price, provided the restoration was done to a high standard and with authentic parts.
• Demand: The demand for specific models can fluctuate based on market trends and collectors’ interests. For instance, a popular model among vintage boat enthusiasts might fetch a higher price than a less sought-after model.

To determine the approximate value of your Johnson outboard, you can consult online resources, such as vintage outboard forums, websites dedicated to antique marine engines, and auction sites. You can also contact a reputable marine antique dealer for a professional appraisal.

Remember that the value of a vintage outboard is subjective and can vary depending on the buyer and the market conditions. Do your research, compare prices, and consider the factors mentioned above to arrive at a fair market value.
