Aluminum alloy boat engines need to be regularly tested and replaced with water and oil. If you change the engine oil from time to time, you will find that many are thick and greasy like asphalt after turning on the engine. Greasy is caused by frequent oil changes that lead to deterioration and oxidation of the oil, or the quality of the oil is not up to standard. Too little antioxidant is added, causing greasy to adhere to the engine, forming a kind of "oil calcium", causing serious engine wear, and losing lubrication to the engine is likely to "seize" and cause the yacht to break down. Next, let's take a look at the maintenance knowledge of the aluminum alloy boat engine with the editor.
