As the autumn wind blows, the autumn atmosphere becomes chilly. When winter comes, our beloved Yamaha 2 Stroke 15HP Outboard Motor also needs rest and maintenance. But don't worry, the outboard motor also requires special care to withstand the cold. Today, let's talk in detail about how to professionally maintain the outboard boat motor and give it a winter sleep spa.
Winter is very harsh on engines. Just imagine: if we drink a large glass of water and then walk into a freezer, wouldn't we feel extremely cold and uncomfortable? The same feeling would occur if there was moisture inside the boat engine in winter. As the temperature drops, the moisture freezes and expands, causing damage to the machine. If there is fuel inside the outboard engine, over time, the fuel will deteriorate and cause corrosion. Therefore, it is very important to maintain the outboard motor during winter.
The steps for winter maintenance of the Yamaha 2 stroke 15hp outboard motor are as follows:
● Complete And Thorough Cleaning
After your last voyage, don't rush to go home. Give the boat motor a gentle bath with fresh water, just as we wash off sweat after exercising, removing salt and sediment. Pay special attention to cleaning the water intake and exhaust ports, as these are the areas most prone to accumulation of dirt and debris.
● Replace With New Lubricating Oil And Gear Oil
While the engine is still warm (just like when your pores are dilated after exercising), replace the lubricating oil. Don't forget to change the gear oil at the bottom as well. This is equivalent to replacing the engine's blood and joint fluid at the same time. The old oil is definitely dark; after all, it has been working for a long time and contains debris from wear and tear, looking dark and dirty.
● Add Stabilizer
The fuel system is most prone to digestive problems. We need:
① Just like emptying the stomach, empty the fuel tank and pipelines.
② Fill up the fuel tank and add the stabilizer at the same time. Let the machine idle for 10 minutes to evenly distribute it and avoid clogging. Next spring, turn it on, and the gasoline will still be as fresh as ever.
● Rust Prevention Treatment
Remove the spark plugs, spray the cylinder with the special rust-preventing oil. Then gently pull the start rope a few times, as if giving a gentle massage to the heart of the engine, allowing the protective oil to evenly cover every corner. Finally, remember to put the spark plugs back in, covering the heart with a "blanket".
● Drain The Last Drop Of Coolant
Draining all the coolant is the key to preventing freezing. Start the engine for a short period of time with a freshwater supply, then turn it off. Pull the rope manually several times, just like gently squeezing a sponge, to completely drain out the remaining water. Remember: Make sure to completely drain all the coolant; there should be no leftovers.
● Maintenance And Storage
① Apply lubricating oil to all the throttle and tilt mechanisms, just as you apply hand cream to your hands.
② Remove the battery, place it in a warm and dry corner, and remember to charge it from time to time to keep it fully charged.
③ Cover it with a breathable dust-proof cover and place it upright in a dry and sheltered area. If possible, place a wooden block underneath to make it more comfortable to stand on.
The instruction manual is our user's best friend. The manual is the most authoritative guide. Different brands of outboard motors are like people with different personalities; some are bold and straightforward, while others are delicate and refined. Spending 10 minutes reading the manual is much more cost-effective than spending money on repairs in the spring. When heavy snow is falling, we ourselves are sitting in the garage with the outboard engine wrapped warmly, dreaming about the blue waves. But an engine that is not maintained is shivering in the cold wind, with its interior gradually freezing and rusting. The contrast is so obvious.
You should know that maintenance is not a hassle; it's an annual commitment with our yamaha outboard motors. The outboard engines take us on thrilling rides on the water, and we should ensure they have a safe winter. This mutual support is the warmest part of our time on the water.
