There are several compelling reasons to consider buying used outboard motors. Significantly, it’s more affordable than purchasing a brand-new model. Also, much like automobiles, outboard motors depreciate the most during their first few years. Buying used means you avoid this steep initial depreciation, allowing you to get more for your money.

Where to Buy?


Established dealers typically offer a range of used outboard motors, often with limited warranties. Their expertise can be beneficial in finding a reliable motor that suits your needs.

Private Sellers

Private sellers may offer more competitive prices but usually without warranties. It’s crucial to thoroughly assess the motor’s condition and ensure it’s a worthwhile investment.

Online Platforms

Various online platforms connect buyers and sellers, broadening your options. Ensure you can inspect the motor in person before finalizing the transaction.

Inspection is Paramount

External Check

Start by examining the external condition of the motor. Look for signs of excessive wear, damage, or corrosion, which could indicate potential issues.

Propeller and Lower Unit

The propeller and lower unit should be free of damage and corrosion. Check the propeller’s condition, ensuring it turns smoothly, and the blades are not bent or chipped.

Compression Test

A compression test measures the engine’s cylinder compression and can highlight potential internal issues. A consistent reading across

all cylinders is a good sign.

Spark Test

Conduct a spark test to ensure the ignition system is in working condition. An inconsistent or weak spark can indicate problems that might require expensive repairs.

Test Run

If possible, request a test run to assess the motor’s performance on the water. Listen for unusual sounds, and observe the motor’s smoothness and responsiveness.

Necessary Paperwork

Ensure the seller has the appropriate paperwork, including the motor’s service history, user manuals, and any relevant receipts or warranties. A clear record can offer insight into the motor’s maintenance and potential longevity.

Parts and Service Availability

Before purchasing, confirm the availability of parts and service for the used outboard motor model. Older models or less common brands may have limited availability, making repairs and maintenance a challenge.

Tallying the Total Cost

While the initial cost may be lower, don’t forget to account for potential repairs, maintenance, and part replacements. Consider these expenses when calculating the total investment.

Final Thoughts

Taking the time to thoroughly research, inspect, and assess a used outboard motor can significantly contribute to a satisfying and successful purchase. Equipped with the necessary knowledge and awareness, you can confidently navigate the market, ensuring your selected motor propels you smoothly through many aquatic adventures to come.

Conduct Research

Spend ample time researching different motor brands, models, and their reputations. Forums, online reviews, and expert opinions can offer valuable insights and highlight any recurring issues with particular models.

Communicate Clearly

Whether dealing with private sellers or dealers, clear communication is crucial. Prepare a list of pertinent questions regarding the motor’s history, performance, and condition. Honest and transparent answers can provide a clearer picture and aid in making an informed decision.

Negotiate Wisely

Negotiation is an integral part of the buying process. Armed with your research and inspection results, you are in a position to negotiate a fair price, reflecting the motor’s condition and value.
