A well-maintained engine cowling is a sign that the motor has been cared for properly.
• Propeller: Inspect the propeller for any dings, bends, or cracks. A damaged propeller can cause vibrations and reduce the motor’s efficiency. Check the propeller shaft for any signs of damage or corrosion, as this could indicate that the motor has been improperly stored or maintained. Make sure the propeller is securely attached to the shaft and that the propeller nut is tightened properly. A damaged or improperly installed propeller can be a safety hazard, so it's important to ensure that it's in good condition before operating the motor.
• Lower Unit: Examine the lower unit for any signs of leaks, cracks, or corrosion. The lower unit houses the gears and bearings that transmit power from the engine to the propeller, so it's essential to ensure that it's in good condition. Check the oil level in the lower unit and look for any signs of water contamination, which could indicate a leak in the seals. Inspect the skeg (the fin at the bottom of the lower unit) for any signs of damage, as this could affect the motor's handling. A well-maintained lower unit is crucial for the reliable operation of the motor.
• Cables and Hoses: Check all cables and hoses for cracks, fraying, or leaks. These components are essential for the proper functioning of the motor, so it's important to ensure that they're in good condition. Look for any signs of wear or damage, such as cracks, cuts, or abrasions. Make sure the cables and hoses are securely attached to the motor and that the connections are tight. Replace any damaged or worn cables and hoses before operating the motor to prevent potential problems and ensure safe operation.

2. Start-Up and Performance

Next, observe how the motor starts and runs. A healthy Yamaha 15 HP should start easily and run smoothly.

• Cold Start: A good sign of a well-maintained motor is how easily it starts when cold. It should fire up quickly without excessive cranking. If the motor struggles to start or requires multiple attempts, it could indicate a problem with the fuel system, ignition system, or compression. Listen for any unusual noises during start-up, such as knocking, rattling, or grinding, as these could indicate internal damage. A smooth and easy cold start is a sign that the motor has been properly maintained and is in good condition.
• Idle Speed: Once started, the motor should idle smoothly without stalling or sputtering. The idle speed should be consistent and not fluctuate excessively. Listen for any unusual noises or vibrations that could indicate a problem with the engine. If the motor idles rough or stalls frequently, it could indicate a problem with the carburetor, fuel system, or ignition system. A smooth and stable idle is a sign that the motor is running properly and is in good condition.
• Smooth Acceleration: Test the motor’s acceleration. It should respond quickly and smoothly when you increase the throttle. Hesitation, sputtering, or lack of power could indicate issues with the carburetor or fuel system. Pay attention to how the motor responds at different throttle positions. It should accelerate smoothly and without any hesitation or lag. If the motor struggles to accelerate or lacks power, it could indicate a problem with the fuel system, ignition system, or compression. A smooth and responsive acceleration is a sign that the motor is in good condition and is ready to perform.
• Listen for Unusual Noises: Pay attention to any unusual noises, such as knocking, rattling, or grinding. These could indicate internal damage or wear. Listen carefully to the motor as it runs and try to identify the source of any unusual noises. If you hear anything that sounds out of the ordinary, it's best to have the motor inspected by a qualified mechanic before making a purchase. Unusual noises can be a sign of serious problems that could lead to costly repairs down the road.

3. Check the Engine Oil

Inspect the engine oil for its condition. The oil should be clean and free of contaminants.

• Color and Consistency: The engine oil should be clean and clear, not dark or sludgy. Dark or sludgy oil could indicate that the motor has not been properly maintained or that there is internal damage. The oil should also be free of any contaminants, such as water or metal particles. If the oil appears milky or contains metal particles, it could indicate a serious problem with the engine. A quick check of the oil's color and consistency can provide valuable clues about the motor's overall condition.
• Smell: Check for a burnt or gasoline smell, which could indicate overheating or fuel leakage into the oil. The oil should have a clean, neutral smell. If it smells burnt or has a strong gasoline odor, it could indicate a problem with the engine. A burnt smell could indicate that the engine has overheated, while a gasoline smell could indicate that fuel is leaking into the oil. These are serious problems that should be addressed before operating the motor.

4. Compression Test

A compression test is a crucial step in evaluating the health of the engine. This test measures the pressure inside each cylinder, providing insights into the condition of the pistons, rings, and valves. Here’s why it’s so important:

• What It Reveals: A compression test reveals the condition of the engine's internal components. Low compression can indicate worn piston rings, damaged valves, or a blown head gasket. These issues can lead to reduced power, poor fuel economy, and eventual engine failure. By measuring the compression in each cylinder, you can get a clear picture of the engine's overall health and identify any potential problems before they become major headaches.
• How to Perform: Ideally, have a professional mechanic perform a compression test. They have the tools and expertise to accurately measure the compression in each cylinder. The test involves removing the spark plugs and inserting a compression gauge into each cylinder. The engine is then cranked over, and the gauge measures the maximum pressure reached in each cylinder. The readings are compared to the manufacturer's specifications to determine if the engine is in good condition.
• Interpreting Results: The compression readings should be consistent across all cylinders. A significant difference between cylinders could indicate a problem with one or more of the engine's internal components. Low compression in one or more cylinders could indicate worn piston rings, damaged valves, or a blown head gasket. These issues should be addressed before operating the motor to prevent further damage and ensure reliable performance. A compression test is an essential step in evaluating the health of a used Yamaha 15 HP outboard motor.

5. Check for Documentation

Ask the seller for any available documentation, such as maintenance records or repair invoices. This can give you a better understanding of the motor’s history and how well it has been maintained.

• Maintenance Records: Regular maintenance is key to the longevity of any outboard motor. Ask the seller for any records of oil changes, tune-ups, and other routine maintenance. These records can give you a good idea of how well the motor has been cared for and whether it has been properly maintained. Look for records of regular oil changes, filter replacements, and lubrication of moving parts. If the seller can provide detailed maintenance records, it's a good sign that the motor has been well-maintained and is in good condition.
• Repair Invoices: If the motor has undergone any repairs, ask the seller for copies of the repair invoices. These invoices can provide valuable information about the nature of the repairs, the parts that were replaced, and the mechanic who performed the work. Look for invoices that indicate the motor has been repaired by a qualified mechanic using genuine Yamaha parts. If the seller can provide detailed repair invoices, it's a good sign that the motor has been properly repaired and is in good condition.
