After purchasing a new Yamaha Outboard Motor, how should we properly store our Yamaha outboard motor engine? This is the question we are considering. Proper storage can extend the lifespan of our machine and maintain its stable performance. So, today we will mainly talk about the precautions for storing Yamaha outboard motors.
① Thorough Cleaning And Inspection:
If we need to store our yamaha outboard motor, the first step is definitely to thoroughly clean the machine. After use, the lower part of the motor body will definitely be covered with mud, sand and algae. Moreover, seawater contains salt, and salt, mud, and algae are all invisible killers that cause corrosion. It is necessary to rinse the motor body with fresh water. After the rinsing is complete, dry the surface and wipe off stubborn stains with a cloth.
After cleaning, conduct a thorough inspection of the entire body to check for any wear, damage, or oil leakage.
② Handling The Fuel System:
If the engine starts with difficulty, it is likely that the fuel has deteriorated. The specific handling methods are as follows:
• Empty the fuel: Empty the fuel completely to ensure there is no residual fuel left.
• Add stabilizer: If you need to keep the fuel, you should add a fuel stabilizer.
• Before storing the outboard engine for a long period of time, the fuel system must be properly handled.
③ Lubrication and Rust Prevention:
After starting the engine and running it for a few minutes, apply the anti-rust lubricant. If smoke is emitted from the exhaust pipe, it indicates that a protective film has formed on the cylinder walls. Then, start lubricating the moving parts.
④ Battery Maintenance:
Immediately disconnect the battery connection. Do not overlook this step. After disconnecting the battery connection, clean the terminals and apply vaseline to prevent oxidation. At the same time, place the battery in a dry and cool place. Charge it once a month to maintain the battery in a good condition.
⑤ Internal Cooling System Anti-freezing:
If it is stored in winter or in cold weather, the cooling water must be emptied. Open the drain plug and let the engine run idle to remove the remaining moisture.
⑥ Suitable Storage Environment:
What kind of environment is the most suitable for storing boat motors? A dry and well-ventilated indoor environment is the best choice for storing the engines. It is best to use wooden supports and cover them with breathable, dust-proof covers. Note: Do not place the outboard motor directly on the ground to avoid moisture.
If you need to store the boat engine for a long time, the following steps are required:
• Remove the spark plugs, inject engine oil, and reinstall them.
• Rotate the crankshaft every month.
• Store the engine upright to prevent engine oil from seeping into the cylinders.
After being stored for a long time, when using the outboard motor again, the following steps are required:
• Install fully charged batteries;
• Check all connection points;
• Add fresh gasoline to the fuel tank;
• After starting, observe whether the machine runs smoothly.

Follow the steps above to store the yamaha outboard motor correctly. This not only saves maintenance costs but also ensures abundant power and safety during each voyage. You should know that true reliability is not just the powerful output in rough seas, but also the peaceful and unchanged performance over a long period of time.
