Where to Find Johnson 40 HP Outboard Motors for Sale

Alright, let's talk about where to actually find these Johnson 40 HP outboard motors! You have several options, each with its pros and cons. Here's a rundown:

• Online Marketplaces: eBay, Craigslist, and Facebook Marketplace are goldmines for used outboard motors. You can often find a wide variety of Johnson motors here, with different price points and conditions. The key is to be patient and diligent. Check listings regularly, and don't be afraid to ask questions. Photos are your friend, so scrutinize them carefully. Be prepared to travel if necessary, as the best deals may be a little further from home. Always arrange to meet the seller in person to inspect the motor before making a purchase.
• Specialized Marine Websites: Some websites are dedicated specifically to selling used boats and motors. These sites often have a better selection, and the sellers may have already performed some basic inspections or maintenance. Websites specializing in marine equipment sometimes offer warranties or have policies in place to help resolve any issues that may arise after purchase. This can provide some peace of mind compared to buying from individual sellers. Consider sites that allow you to filter by motor make, horsepower, and location to narrow your search.
• Local Boat Dealers and Repair Shops: Don't underestimate the value of checking with local boat dealers and repair shops. They often take trade-ins and may have used motors in stock. These sources can be valuable because you can talk to someone in person, ask for advice, and see the motor running before you buy it. They may also be able to offer a limited warranty, which adds value. Repair shops have the added benefit of being able to assess the motor's condition and address any potential problems.
• Boat Shows and Swap Meets: Keep an eye out for boat shows and marine swap meets in your area. These events are great for finding a wide range of marine equipment. You can see many motors in one place. You can negotiate prices directly with the sellers and often find great deals. Boat shows and swap meets are excellent places to find not only motors, but also accessories, parts, and get advice from experts.
• Auctions: Sometimes, you can find Johnson 40 HP outboard motors at auctions, either online or in person. Auctions can be a gamble, but sometimes you can snag a great deal. However, always know your limits and stick to your budget, as auction prices can quickly escalate. Be sure to check the motor out thoroughly during any preview period.

What to Look for When Buying a Used Johnson 40 HP Outboard

Okay, you've found a motor that interests you. Now, it's time to put on your detective hat! Here's what you should look for when inspecting a used Johnson 40 HP outboard motor:

• Overall Condition: Start with a visual inspection. Look for signs of corrosion, especially around the lower unit, the powerhead, and any electrical connections. Minor cosmetic issues are normal for a used motor, but significant rust or corrosion can be a sign of deeper problems. Examine the engine's exterior, including the cowling (cover), for any cracks or damage. Any major damage will require attention. The exterior condition often reflects the level of care and maintenance the motor has received.
• Compression Test: This is a crucial test to determine the engine's health. You'll need a compression tester. The compression test measures how well the cylinders are sealing. Low compression in one or more cylinders indicates wear and tear on the pistons, rings, or valves, which can lead to poor performance and expensive repairs. Each cylinder should have similar compression readings, usually between 90 and 120 PSI. If compression is low or uneven, it's a major red flag.
• Lower Unit Inspection: The lower unit (the part of the motor below the powerhead) is responsible for transferring power to the propeller. Check the gear oil for any signs of water or metal shavings, which could indicate a problem with the gears or seals. Water intrusion is a common issue that can lead to corrosion and damage. You should also check the propeller for any damage or excessive wear.
• Engine Start and Run: If possible, have the seller start the motor and let it run for a while. Listen for any unusual noises, such as knocking, clunking, or grinding. Observe the engine's idle and acceleration. A healthy engine should start easily, idle smoothly, and accelerate without hesitation. Watch for excessive smoke, which could indicate a problem with the rings or seals. Check that the engine shifts into forward, neutral, and reverse smoothly.
• Maintenance History: If possible, ask the seller for any maintenance records. This can give you an idea of how well the motor has been cared for. While it's not always available, any maintenance history is a plus. Evidence of regular oil changes, tune-ups, and other maintenance suggests that the motor has been well-cared for and is more likely to be in good condition. If the motor comes with a recent service, you can be reasonably assured it is in excellent condition.
• Check the Tilt and Trim: Test the motor's tilt and trim functionality (if equipped). This system allows you to raise and lower the motor for different water conditions. Ensure it operates smoothly and doesn't struggle or make unusual noises. If the tilt and trim are electric, ensure the motor has adequate charge for the battery. Any issues with the tilt and trim could be an early indicator of a problem.
• Propeller Condition: Inspect the propeller for any damage, such as bent blades, chips, or erosion. A damaged propeller will affect the motor's performance and efficiency. Small chips are often manageable, but significant damage will require propeller replacement. Also, check the propeller for any signs of wear.

Negotiating the Price and Closing the Deal

So, you've done your research, inspected the motor, and now it's time to talk money! Here are some tips for negotiating the price of a used Johnson 40 HP outboard motor:

• Know Your Budget: Before you even start looking, set a budget. This will prevent you from overspending. Your budget should include not only the purchase price but also any potential repair costs. Remember, with a used motor, some maintenance may be necessary, so plan for it. Make sure you can comfortably afford the motor and any related costs.
• Research Market Value: Before making an offer, research the market value of similar Johnson 40 HP outboard motors in your area. This will give you a benchmark to work from. Check online marketplaces to see what similar models are selling for. This knowledge is crucial for making a fair offer and negotiating a good deal.
• Point Out Any Issues: If you find any problems during your inspection, use them to your advantage. Point out any areas that need repair or maintenance. This can be a valid reason to negotiate a lower price. If the motor needs a new water pump, tell the seller. If you know that work is needed, it strengthens your negotiation position.
• Be Prepared to Walk Away: Don't get emotionally attached to the motor. If you can't agree on a price that you're comfortable with, be prepared to walk away. Plenty of other motors are available, and you don't want to overpay. Don't let yourself feel pressured to buy something you're not confident about.
• Payment and Paperwork: Once you've agreed on a price, make sure you get everything in writing. A bill of sale should include the motor's serial number, the agreed-upon price, and the date of the sale. If possible, pay with a method that provides a record of the transaction (e.g., check, bank transfer). If the motor came with any paperwork (e.g., owner's manual, registration), make sure you get it.

Maintaining Your Johnson 40 HP Outboard

Congratulations, you've bought a Johnson 40 HP outboard motor! Now, the key to its longevity is proper maintenance. Here are some essential maintenance tips:

• Regular Oil Changes: Change the engine oil and the gear oil regularly, following the manufacturer's recommendations. This is critical for keeping the engine running smoothly and preventing wear and tear. Use the correct type and quantity of oil specified by Johnson.
• Tune-Ups: Get regular tune-ups, including replacing spark plugs, checking the ignition system, and adjusting the carburetor (if applicable). This will improve performance and fuel efficiency. A well-tuned engine runs better and lasts longer.
• Fuel System Maintenance: Use a fuel stabilizer to prevent the fuel from going stale, especially if you won't be using the motor for an extended period. Regularly inspect the fuel lines and fuel filter. Fuel-related issues are a common cause of engine problems. Replace the fuel filter and fuel lines as needed.
• Cooling System Flush: Flush the cooling system regularly, especially if you use the motor in saltwater. This helps to prevent corrosion and keep the engine running at the correct temperature. A clogged cooling system can lead to overheating and engine damage.
• Storage and Winterization: If you're not using the motor for an extended period, properly winterize it. This includes draining the fuel, adding a fuel stabilizer, fogging the engine, and lubricating critical components. Proper storage protects the motor from the elements and prevents damage during the off-season.
• Regular Inspections: Regularly inspect the motor for any signs of wear or damage. Check for leaks, corrosion, or any other issues that might require attention. Catching problems early can prevent them from becoming major and costly repairs.

Common Issues and Solutions for Johnson 40 HP Motors

Even the best-maintained Johnson 40 HP outboard motors can experience issues. Here are some common problems and potential solutions:

• Hard Starting: If the motor is hard to start, check the spark plugs, fuel supply, and compression. Common causes include fouled spark plugs, a clogged fuel filter, or low compression. A simple tune-up or cleaning the carburetor might resolve this.
• Poor Performance: If the motor is not running at its full potential, check the spark plugs, carburetor, and propeller. Common causes include a dirty carburetor, a damaged propeller, or low compression. Proper tune-up can enhance performance.
• Overheating: If the motor is overheating, check the cooling system, including the water pump and thermostat. Common causes include a clogged cooling system or a faulty water pump. Make sure the cooling system is clean and working. If you're experiencing problems with your engine, don't hesitate to consult a qualified marine mechanic. They will be able to diagnose and fix any issues.
• Fuel Leaks: Check the fuel lines, fuel pump, and carburetor for leaks. Fuel leaks can be dangerous and lead to engine damage. Make sure the fuel system is leak-free. Address any leaks immediately. This is critical for both safety and engine longevity.
• Water in the Gearcase: Check the gear oil for water intrusion, which could indicate a bad seal. Water in the gearcase can lead to corrosion and damage. Replace the gearcase seals and fill with fresh gear oil. Regularly check the oil for signs of water. This is a common issue with a straightforward fix.
