marine gauges outboard

What does the instrument on the marine or speedboat mean? Engine revolution, RPM represents the speed per minute, X1000 represents the multiple of the indicated number on the table. 1 means 1000 rpm, and 5 means 5000 rpm. What if the speedboat engine tachometer does not display?  It can be replaced directly. Our company provides an marine outboard engine tachometer. The marine outboard speedboat engine tachometer does not display data because the tachometer gauge is damaged. Replace it with a new instrument to check it. If it is indeed damaged, it is recommended to replace it directly.

Generally, the speed of speedboats can reach 40-60 knots. For easy understanding. It is necessary to convert the units: the speed of vehicles on land and aircraft in the air, as well as river ships, is usually measured in kilometers (kilometers) per hour, while the speed unit of sea ships (including warships) is called "knots". One knot=1 nautical mile/hour, one nautical mile=1.852 kilometers. Therefore, the average speed of speedboats is 74-111 km/h. The engine speed of marine Yamaha outboard engine is 4500~5500 r/min. High-speed speedboats have outboard engines, internal jet pumps and surface propellers. The outboard engines have more than 6000 rpm, the jet pumps have more than 6500 rpm, and the surface propellers have more than 6000 rpm. All low-speed boats with less than 6000 rpm are not speedboats. The most fuel-efficient is that the slower the engine is, the more fuel-efficient it is. However, it is impossible for the speedboat to not increase the throttle just to save fuel. The speed of the external engine of the speedboat is 6000~6200 rpm, and the most fuel-efficient and fast speed is 4000~4200 rpm, which is the speed at which the speedboat just flies on the water. What is the speed of yamaha speedboat? The maximum rotational speed of gasoline on hook is 5500-6000, which is normal. If the rotational speed is too low, see if the propeller is too big!

What is the reason why the speed of Yamaha marine outboard speedboat doesn't work? There may be insufficient elasticity. The reason why the speed of Yamaha 300 speedboat can't work is that the insufficient spring force will reduce the speed regulation sensitivity of the governor, and the stable range of the diesel engine speed will increase, from high to low. At this time, the governor spring should be replaced. There may also be a problem with the tachometer, which should be checked at this time. If it is broken, it should be replaced and repaired in time.
