The yamaha boat gauge include tachometer , speedometer , rudder angel indicator and so on. Customers can add the gauges which are needed. Also can add a 300*190mm gauge panel on the boat.

The speed of an ordinary general yamaha boat is 12-15 knots, or 22-27 km/h. The difference between the tachometer and the speedometer is mainly reflected in the function, unit and scope. The specific differences are as follows: different functions: the speedometer reflects the distance traveled by the ship every hour. The speed is actually composed of two instruments, one is the speedometer and the other is the odometer. The tachometer reflects the engine revolutions per minute. The engine tachometer can visually display the engine speed under various working conditions. The driver can know the running condition of the engine at any time, cooperate with the gear and accelerator position of the transmission to keep it in the best working condition, which is conducive to reducing fuel consumption and prolonging the service life of the engine. Different units: the unit of tachometer is RPM; The unit of speedometer is km/h. Different ranges: the speedometer refers to the running speed of the vehicle within the general range of 0-300km/h; Tachometer means that the engine speed is generally 0-8000 rpm.

The speed of a ship refers to the distance that the ship travels relative to the seabed in unit time. It affects the shipping cycle, shipping operation cost and shipping competitiveness, and is an important technical performance of transport boats . When the rated power, rated speed and water depth are sufficient , the speed that the boat can reach in still water is called rated ship speed, also called delivery speed , which is the highest ship speed of the ship. In order to ensure the safety of the main engine , it is necessary to reserve appropriate power of the main engine . Therefore, the main engine is operated according to the common output power of the sea , usually 90% of the rated power, and the corresponding speed of the main engine is 96%~97% of the rated speed. The boat speed at this time is called the ship speed at sea. The ship speed at sea is divided into full load and no-load (ballast) ship speed. With the wear of the main engine and the aging of the hull, the ship speed will be reduced .
