1. The Yamaha motorboat 700 is powerless to accelerate and smokes because it is time for maintenance.The normal wear of the engine during the use of the Yamaha Motorboat 700 will cause a decrease in power. At this time, the engine needs to be maintained frequently. If the maintenance is delayed, it may cause the start-up and the acceleration will be weak and smoke.

2. Insufficient elasticity. The reason why the speed of the Yamaha 300 speedboat is not enough will reduce the sensitivity of the speed regulation of the speed adjuster, and the stability range of the diesel engine speed will increase, suddenly high and low. At this time, the speed regulation spring should be replaced.

3. The pulley is worn. The wear of the belt, pulley, etc. of the transmission system will cause the Yamaha motorboat engine to increase the speed, but the rotation speed cannot increase. Yamaha is also a comprehensive international group engaged in music popularization, network products, sports goods, kitchen and bathroom supplies, engines, chip machines and other products.

4. Due to the failure of the clutch, the clutch separation stroke is insufficient, resulting in the incomplete separation of the clutch and the inability to enter the gear. In this case, it is recommended to go to the repair shop to adjust the separation schedule.

5. The main reason for burning engine oil is to use engine oil of poor quality or viscosity level that does not meet the requirements. Low oil quality level will lead to increased wear. In addition, if the viscosity of the oil is too low or too high, it will cause poor engine lubrication, which will increase the wear of the piston ring and cylinder wall, and the sealing performance will decrease, resulting in oil burning.

6. Look whether the ventilation port of the fuel tank is open. Sometimes the oil can't be sucked in if you forget to open it, and you won't be able to add the accelerator.

How to repair the Yamaha motorboat engine falling into the water

With such oil, it is impossible for the car not to break down.No antifreeze is added. Some car owners add water or poor-quality antifreeze to the car. As a result, in a particularly cold winter, the whole waterway is frozen and the engine is frozen, resulting in the inability of the car pump to operate, the inability to ignite, and other parts of the engine are injured.

Engine wear, air filter failure. The normal wear of the engine during the use of the Yamaha motorboat 700 will cause a decrease in power. At this time, the engine needs to be maintained frequently. The air filter of Yamaha Motorboat 700 causes blockage or damage, which will also lead to insufficient power. At this time, the filter element needs to be cleaned or replaced.

Look at whether the ventilation port of the fuel tank is open. Sometimes you forget to open the oil and can't be sucked in, and you won't be able to add the accelerator.

Check the lifting hydraulic oil, and there is no problem with the hydraulic oil.The carbon brush of the motor is generally located next to the motor, and the black round cover is symmetrical on both sides. Unscrew the round cover counterclockwise with a matching screwdriver, and the carbon brush will pop out by itself. In this case, there are generally more carbon brush problems and less oil leakage problems, but you should also pay attention to the maintenance of oil.

Where is the water inlet of the Yamaha 650 motorboat engine in the engine?

Above the front of the engine. According to the Yamaha motorcycle information, the air intake of the 60-horsepower Yamaha four-stroke thruster is above the front of the engine, and the position of the intake pipe between the carburetor and the engine.

The upward green lid is unscrewed to the water outlet, and the black screw is unscrewed to add water. The green lid on the side is unscrewed to the water inlet.

Where to add water to the water-cooled motorcycle? It is under the front faucet, and there is a water cap next to the radiator on the upper side of the front wheel. The water-cooled engine has special coolant water. Note that it is not ordinary tap water.

The oil channel of the Yamaha Tianjian 125 engine is on the side of the engine. It is common to place the oil channel on the side of the engine.Configuration, you can look for a component similar to a screw cap or stopper near the bottom of the engine. This position usually has a sign or logo indicating that it is the engine oil channel.

Where is the engine water tank? The car water tank is in front of the engine, right behind the front windward grille of the car (except for the rear engine). It is composed of a water chamber, a water chamber, a heat sink belt and a heat sink outside the pipe belt. The pump on the engine pumps the hot water into the water supply room and cools it with a cooling pipe. The water tank is in front or behind the fan.

Why is it said that "with Yamaha, Honda will never become the king"?

1. Technology and reliability: Yamaha motorcycles have significant advantages in technology and reliability.Pay attention to details and quality control, and adopt advanced manufacturing processes and technologies to ensure the high quality and reliability of each motorcycle. Yamaha Motor's manufacturing standards and quality control processes help reduce the failure rate and provide a longer service life.

2. Speaking of Honda, except for China, Honda ranks first in the world in sales. Honda's best-selling price is not because of its cheapness, but because of its quality. In the United Kingdom, the CG125 of Honda thimble machine is the same as Yamaha's YBR125. In Brazil, the sales volume of CG125 is also the highest every year, even more than two-thirds of the annual sales.

3. The appearance must be more attractive than Honda. For example, Yamaha is a sports car and Honda is a family car. There are two concepts. In terms of domestic quality, YAMAHA must beIt is better than Honda, because yAMAHA is better than Honda on the manufacturer's management system.
