For the engine, the oil and water temperature are very important. Engine oil is the blood of a yacht. Water is like the water in the human body. Whether the water temperature is appropriate or not directly affects the performance of the engine. The quality of the engine oil also directly affects the degree of lubrication in the engine.

The engine must be tested and replaced regularly for water and oil. If the engine oil is changed irregularly, after turning on the engine, you will find that many of them are thick and greasy like asphalt. Greasy is caused by frequent oil changes and oxidation, or the quality of the oil is not good enough. Too little antioxidant is added, causing greasy to adhere to the engine, forming a kind of "oil calcium", causing severe engine wear, and losing lubrication to the engine is likely to "seize" and cause the yacht to break down. Therefore, it is best to maintain and maintain the engine in accordance with the number of hours specified by the manufacturer.

The abnormal noise of the engine, don't take it lightly. Always pay more attention to whether the engine has abnormal noises, and if you find abnormal noises in the engine, you must repair it in time. Is there a problem with the oil circuit, water circuit, or ignition system and fan?

When the water temperature is high, the engine oil becomes thinner, because the engine oil is also cooled by water. Once the engine oil becomes thinner, the friction gap in the engine becomes smaller at this time, and a metal impact sound similar to "da da da" will be produced. If the water temperature is too high and not adjusted in time, it will cause the oil temperature to be too high and reach the boiling point of the oil to evaporate and produce the burning smell of the oil.

Since most of the engine's cylinder cover is made of aluminum alloy, the purpose of using aluminum alloy engine is to better help the vehicle's engine to dissipate heat, so it is very sensitive to temperature changes. Once the water temperature reaches a high temperature of 100 degrees or even 200 degrees, the aluminum alloy engine is prone to warp and cause water leakage. A large amount of water may be poured into the engine and cause the engine to stall or break down.
