mercury outboard tachometer on dash board

• 2023-08-10

We recommend mercury outboard dash board tachometer with 3000 RPM. We have single tachometer and also have dash board include the tachometer. The Tachometer can be installed on the left side of the dashboard. The Tachometer on the bridge of the ship displays the working state of the engine, which is installed on the left side of the dashboard to remind the driver of the working state of the engine. The Tachometer is an instrument that displays the engine speed. The number displayed is to express how many revolutions the engine crankshaft can turn per minute. If it shows 2000 revolutions, it means that the crankshaft of the car engine can rotate 2000 revolutions per minute. In the same gear, the higher the engine speed, the faster the mercury outboard runs. 

If mercury outboard travels a long distance, there will definitely be some wear and tear inside the engine. So as the speed increases, the engine's working sound will definitely become louder. If there is no abnormal sound when the engine is working normally, it is normal. If there is a strange noise, it is definitely wrong. You can go and check if you're not sure. The 3000 rpm engine shakes severely. I suggest you check the engine bracket. Personally, I think it may be due to the aging and cracking of the rubber components inside the engine bracket, which cannot provide shock absorption. Therefore, you may feel that the engine shakes severely. 

Select appropriate connectors, such as rubber joints, based on the specific situation of the tested rotating object. Use the rotary range switch to select the appropriate range (turn the scale value to the same level as the dial). If an unknown quantity is measured, a large range should be selected for rough measurement before determining the range. Make the test shaft of the Tachometer contact with the measured shaft, keep a certain pressure to run synchronously, and keep it on the same centerline. After the Tachometer pointer is stable, the rotational speed of the measured rotating object can be measured. The speed is equal to the ratio of the upper range limit selected by the range switch to the full range of the reading plate multiplied by the reading plate. When measuring linear speed, a wheel test head should be used. The measured reading is converted according to the following formula: linear speed (m/min)=(upper range limit selected by the range switch/full range of the reading dial) × Tachometer × The circumference of the wheel test head.
