How to Choose the Best Used Outboard Motor: A Complete Buyer’s Guide
Buying a used outboard motor can be a cost-effective way to power your boat while still getting reliable performance. However, not all used outboards are created equal, and making the wrong purchase can lead to costly repairs and disappointment. This guide will help you navigate the buying process, ensuring you get a high-quality motor that meets your needs.
Why Buy a Used Outboard?
Many boat owners opt for used outboards because they offer significant savings compared to new models. Additionally, well-maintained outboards from top brands like Yamaha, Honda, Suzuki, and Mercury are built to last, making them a smart investment if you choose wisely.
Key Factors to Consider When Buying a Used Outboard
1. Engine Type: 2-Stroke vs. 4-Stroke
- 2-Stroke Engines are generally lighter, simpler, and offer strong acceleration but may consume more fuel.
- 4-Stroke Engines are quieter, more fuel-efficient, and environmentally friendly, making them a popular choice for long-term use.
2. Horsepower and Boat Compatibility
Choosing the right horsepower depends on your boat’s weight and intended use. Check your boat’s manufacturer recommendations to ensure compatibility.

3. Engine Hours and Wear
Outboards track their running time in hours. Generally, a well-maintained motor with less than 500 hours is a good buy, but always consider maintenance records over just engine hours.
4. Compression Test & Performance Checks
A compression test ensures the cylinders are functioning correctly. If compression levels are uneven, the engine may have underlying issues that could lead to costly repairs.
5. Maintenance and Service History
A well-maintained outboard will have a documented service history. Look for motors that have undergone regular oil changes, fuel system maintenance, and impeller replacements.
6. Signs of Wear and Corrosion
- Check the propeller for damage
- Inspect the engine cover for cracks or rust
- Look for signs of corrosion on the lower unit, especially if the motor was used in saltwater
Where to Buy a Used Outboard Safely
- Reputable Dealers: Buying from trusted suppliers like Yamaha Source ensures you get quality-tested outboards with warranty options.
- Private Sellers: If buying from an individual, always ask for maintenance records and perform a thorough inspection.
- Online Marketplaces: Be cautious and always verify the seller’s credibility before making a purchase.
Final Tips for Getting the Best Deal
- Test the motor in person before buying
- Negotiate based on condition and maintenance history
- Check return policies and warranties for added peace of mind
By following this guide, you can make a smart purchase that gives you reliable performance for years to come.
