When it comes to buying an old outboard motor, it’s crucial to assess its condition before making the purchase. Here are a few tips to help you evaluate the overall condition of an older outboard motor.
1. Check the exterior
The first thing that you should do is to check the exterior of the outboard motor. Look for any signs of damage such as dents, scratches or cracks. If you see any of these signs, it could mean that the engine has been involved in some kind of accident. Additionally, check the paint job and decals for any signs of fading.
2. Check the compression
One of the most important things to check is the compression of the engine. Compression refers to the pressure that builds up inside the engine when the piston is moving up and down. A low compression reading could mean that the engine has worn out or has some internal damage. Use a compression gauge to check the compression level of the engine.
3. Test the ignition system
The ignition system is another crucial component of an outboard motor. Make sure to check the spark plugs, coils, and wiring to ensure that everything is functioning correctly. You can use a spark plug tester to check the spark plugs.
4. Inspect the lower unit
The lower unit is the part of the outboard motor that is responsible for transferring power from the engine to the propeller. Inspect the lower unit for any signs of damage or wear such as corrosion, dents, or cracks. Also, check the oil level and condition of lube.
5. Assess the general maintenance
Lastly, assess the general maintenance of the engine. Check the hours clock for regular servicing, and look for any receipts that indicate the previous owner’s maintenance. It is a well-known fact that a well-maintained outboard motor will last longer than one that has been neglected.
Assessing the condition of an old outboard motor is very important before making a purchase. By checking the exterior, compression, ignition system, lower unit, and general maintenance, you can determine the overall condition of the engine. If you’re not confident in your abilities to assess an outboard motor, hire a marine technician that can assist you or more importantly, just purchase a new, reliable engine.
