Used Outboard Motors: A Complete Buying Guide

Buying a boat can be expensive, and the motor is one of the biggest costs. A used outboard motor can save you money, but it's important to do your research before you buy. This guide covers everything you need to know about buying a used outboard motor, including what to look for, how to inspect a motor, and how to negotiate a price.

Why Buy a Used Outboard Motor?

• Cost Savings: The primary advantage is the lower price compared to new motors. You can often find a used motor for significantly less than a new one.
• Depreciation: New outboards depreciate quickly in the first few years. Buying used lets someone else absorb that initial loss.
• Availability: You might find older or discontinued models that fit your boat perfectly but aren't available new.

Things to Consider Before Buying

1. Determine Your Needs

• Boat Size and Type: What size and type of boat will the motor be powering? A small fishing boat needs a different motor than a large pontoon boat.
• Horsepower Requirements: Calculate the appropriate horsepower for your boat. Overpowering can be dangerous, while underpowering can strain the motor.
• Intended Use: How will you use the boat? Fishing, watersports, or cruising will influence your horsepower and feature needs.

2. Types of Outboard Motors

• Two-Stroke vs. Four-Stroke: Two-strokes are lighter and simpler but generally less fuel-efficient and produce more emissions. Four-strokes are more fuel-efficient and cleaner but heavier and more complex.
• Direct Injection (DI): DI two-strokes offer better fuel efficiency and lower emissions than traditional two-strokes.
• Horsepower Range: Outboards range from small, portable motors (2.5 HP) to very large, high-performance models (400+ HP).

3. Budget

• Purchase Price: Set a budget for the motor itself.
• Inspection Costs: Factor in the cost of a professional inspection, which is highly recommended.
• Maintenance and Repairs: Used motors may require maintenance or repairs, so budget for that.

4. Where to Buy

• Private Sellers: You might find good deals, but you'll need to do thorough research and inspection.
• Boat Dealers: Dealers often offer warranties or certified pre-owned programs, providing more security.
• Online Marketplaces: Websites like Craigslist, eBay, and boat-specific forums can be good sources, but exercise caution and verify information.

Inspection Checklist for a Used Outboard Motor

1. Visual Inspection

• Overall Condition: Look for signs of wear, corrosion, or damage.
• Paint and Finish: Check for scratches, dents, or mismatched paint, which could indicate repairs.
• Cowling: Inspect the cowling (engine cover) for cracks or damage. A damaged cowling can let water in and cause corrosion.

2. Mechanical Inspection

• Propeller: Check for damage, dings, or bends. A damaged prop can affect performance.
• Lower Unit: Inspect the lower unit for leaks or damage. Leaks indicate seal problems.
• Engine Oil: Check the oil level and condition. Milky or dark oil can indicate water intrusion or other issues.

3. Compression Test

• Importance: A compression test is crucial to assess the engine's internal health. It measures the pressure in each cylinder.
• Procedure: A mechanic uses a compression gauge to measure the pressure. Low or uneven compression indicates problems.
• Acceptable Range: Consult the engine's specifications for the acceptable compression range. Significant variations between cylinders are a red flag.

4. Spark Test

• Importance: This test checks the ignition system's performance.
• Procedure: A mechanic removes a spark plug, connects it to the ignition system, and looks for a strong, consistent spark.
• What to Look For: A weak or inconsistent spark indicates potential ignition problems.

5. Water Pump Test

• Importance: The water pump cools the engine, so its proper function is critical.
• Procedure: Start the engine and check for a strong stream of water exiting the telltale (pee hole). A weak stream indicates a pump problem.
• Overheating: Overheating can cause severe engine damage, so a functioning water pump is essential.

6. Gear Oil

• Importance: Gear oil lubricates the gears in the lower unit.
• Inspection: Check the gear oil level and condition. Milky or contaminated oil indicates water intrusion, which can damage the gears.
• Replacement: If the oil is contaminated, it needs to be replaced, and the cause of the leak should be investigated.

7. Starting and Running

• Cold Start: Observe how easily the engine starts when cold. Difficulty starting can indicate problems.
• Idle: Listen for smooth idling without excessive noise or vibration.
• Acceleration: Check for smooth acceleration without hesitation or sputtering.
• Smoke: Excessive smoke can indicate engine problems. Blue smoke suggests burning oil, while black smoke suggests a fuel mixture issue.

8. Electronic Diagnostics (If Applicable)

• Engine Hour Meter: Check the engine hours. High hours indicate more wear.
• Error Codes: Newer outboards have electronic control units (ECUs) that store error codes. A mechanic can read these codes to diagnose problems.
• Data Download: Some ECUs can download engine data, providing a detailed history of performance.

Negotiating the Price

• Research Market Value: Find out the typical price for similar motors in your area.
• Point Out Issues: Use any issues found during the inspection as leverage for a lower price.
• Be Prepared to Walk Away: Don't be afraid to walk away if the seller isn't willing to negotiate fairly.

Documents and Paperwork

• Bill of Sale: Get a signed bill of sale that includes the motor's serial number, purchase price, and date.
• Title or Registration: Ensure the seller has the title or registration, as required in your state. Transferring ownership is crucial.
• Maintenance Records: Ask for any maintenance records. These can provide valuable information about the motor's history.

Maintenance Tips for Used Outboard Motors

• Regular Servicing: Follow the manufacturer's recommended service schedule.
• Oil Changes: Change the oil regularly.
• Lubrication: Grease all moving parts.
• Winterization: Properly winterize the motor if you live in a cold climate.

FAQ

What is the lifespan of an outboard motor?

The lifespan of an outboard motor can vary widely depending on factors such as usage, maintenance, and the quality of the motor. However, a well-maintained outboard motor can often last for 1,500 to 2,000 hours or more. For recreational use, this could translate to 10 to 20 years of service. Commercial users, who might put significantly more hours on their motors each year, might see a shorter lifespan in terms of years, but the motor could still achieve a high total number of operating hours. — Marquay The Goat: Cause Of Death

Is it better to buy a used or new outboard motor?

The decision to buy a used or new outboard motor depends on your budget and needs. Used outboard motors are more affordable, but they may require more maintenance and may not last as long as new motors. New outboard motors are more expensive, but they come with a warranty and are less likely to require repairs. — Sugar Grove, WV: Your Complete Guide

How can I tell if a used outboard motor is in good condition?
