Please Check The Winter Maintenance Tips For The Outboard Motor!
Proper protection can extend the life of the outboard engine. "Spring rains start the spring and clear the valley, summer is full of awns, summer and summer are connected. In autumn, there is cold and frost in autumn, snow and snow in winter, and a small cold in winter..." In winter, people need to wear cotton-padded clothes to keep warm. Brush white paint to prevent insects and cold. And the outboard engine is no exception, winter also needs anti-freezing to extend the service life. To share with you the main points of winter maintenance for the outboard motor:
Routine maintenance is to change the oil, engine filter, gear oil, gasoline filter, etc., plus some inspection and lubrication work. Regardless of the marine engine used in winter (inboard engine, outboard engine), special attention must be paid to avoid freezing, rust and corrosion, so as to ensure that it can be rejuvenated when it heats up in the coming year. This is winter maintenance. The meaning of.
1. Anti-corrosion and anti-rust
Engine internal components: flush the inside and outside of the sealed engine with fresh water, discharge sewage, salt and other impurities, reduce the risk of corrosion and blockage in the water channel during storage; the spark plug, fuel injector or glow plug can be removed from the seat hole to each Inject about 30 ml of anticorrosive agent for storage into the cylinder, rotate the engine for a cycle, so that the sealant is evenly distributed in each cylinder, so as to have the effect of sealing and anticorrosion. After the end, install the spark plug, fuel injection nozzle or glow plug. . At the same time, it is necessary to thoroughly lubricate the propeller shaft, rotating shaft frame, bearing and coupling and other locations that need to be lubricated.
Engine external parts: repair the lack of paint on the engine surface with special marine anti-corrosion paint. The outer metal surface of the engine (except the anode) can be sprayed with anti-corrosion spray for anti-corrosion protection.
2. Antifreeze
Drain the external cooling water of the engine: For ships still used in cold weather, the external cooling water of the engine should be drained after berthing; for closed-cooled engines, there is no need to drain the internal antifreeze, but the appropriate label should be selected according to the temperature condition to avoid The cylinder body and waterway components are damaged by freezing; when the outboard motor is placed vertically, it has an automatic drainage function, which is its advantage. But don't forget to lower the engine to a vertical position after landing, or cover it with a waterproof cover to prevent the water produced by rain and snow from freezing and causing damage to the engine or gearbox.
3. Anti-deterioration
The fuel system focuses on: the fuel stored for a long time is easier to separate and deteriorate, and even form a glued substance, which will eventually cause many unpredictable combustion problems. Fuel stabilizer can be said to be the most economical and convenient way to protect the health of the fuel system in winter. After the last time the engine is used up, the fuel stabilizer is added to the fuel tank in proportion to use (a bottle of 355ml stabilizer can handle about 227L of fuel). After adding, run the outboard engine for about 10 minutes to allow the stabilizer to fully enter all parts of the fuel system and play its role. Of course, you can also choose to simply and rudely put all the oil in, store the good fuel separately with a stabilizer, and clean the oil circuit and tank thoroughly by the way.
4. Machine failure check
Important parts inspection: check the important parts that are vulnerable to aging, such as mid-range bellows, anti-wave valves, water pump impellers, drive belts, etc. If there are any abnormalities, they need to be replaced before use in the coming year. If it is not handled in time, it may cause serious consequences. If the bellows is broken, the entire ship may capsize overnight.
5. Always be vigilant, take precautions
Battery "drip feeding": After the boat is ashore, remove the battery as much as possible, place it in a cool and dry place, and maintain it with drip charging (not less than 2 hours per charge) to ensure that the battery is in good condition; otherwise, it will be out of business for a long time. May be abandoned in advance. During storage, operate the throttle controller every few weeks to prevent the waste of moving parts.
