Find the two screws of the mercury Tachometer, one is located in the master schedule dial and the other is located in the hour dial, usually marked. Use a flat screwdriver or specialized adjustment tool for adjustment. First, unscrew the screw on the hour dial and gently adjust the hour dial so that the pointer points to the actual usage time. After adjusting the hour dial, tighten the screws again to ensure that the dial is fixed in the set position. If it is necessary to adjust the overall schedule, follow the same method. However, it should be noted that if the overall schedule dial has been adjusted, adjusting the hour dial will change the position of the overall schedule dial. Finally, start the mercury outboard to test the accuracy of the Tachometer. It should be noted that in order to ensure the safety and accuracy of the outboard engine, professional technicians are recommended to adjust the Tachometer. 

Mercury Outboard : a machine that is not permanently fixed on the outboard and needs to be dismantled and moved ashore for propulsion at any time. Due to its small size, high power, and high speed, it is widely used in high-speed boats, fishing boats, and workboats. The fuel consumption of a two-stroke 40 horsepower marine outboard engine is approximately 20 liters per hour. The fuel consumption of a four stroke 40 horsepower mercury outboard engine is approximately 12-15 . The fuel consumption depends on the engine speed, and the high throttle fuel consumption at 5500 rpm is not as high as it would be if it were around seven minutes of a outboard. 

Is the faster the speed of the mercury outboard , the more fuel-efficient it is? As a professional speedboat driver , the most fuel-efficient thing is that the slower the speedboat , the more fuel-efficient it is. However, speedboats cannot simply increase the throttle to save fuel . The speed of the external engine of the speedboat is between 6000 to 6200 rpm, and the most fuel-efficient and fast speed is between 4000 to 4200 rpm, which is the speed at which the mercury outboard happens to be flying on the water. What brand of machine and what horsepower of machine do you want to tell me , I will tell you how much oil can be burned at any speed in an hour.
