tachometer for 3 cylinder outboard boat

• 2023-02-24

Our tachometer is universal , can be used on many types , such as outboard ,boat , marine, diesel, gasoline , 1 cylinder, 2 cylinder , 3 cylinder and 4 cylinder. Support 12v or 24v. The maximum rotational speed of gasoline on outboard is 5500-6000, which is normal. If the rotational speed is too low, see if the propeller is too big!

Confirm the speed of the fastest propeller. If the design is OK, check whether there is any problem with the connecting structure. Check whether the gasoline engine has enough power and reaches enough speed! Also check the propeller blade height, which affects the load and speed of the gasoline engine! 3 cylinder outboard speedboat engine is 25 horsepower, 25 horsepower, which is the engine of Honda 20 years ago. On even today in 2020, the maximum horsepower of the 2.0L naturally aspirated engine can only reach 170-180Ps. That's right, the 25 horsepower of Lexus, which is the engine of Honda 20 years ago Even today in 2023, the maximum horsepower of the 2.0L naturally aspirated engine can only reach 170-180Ps, yes, Lexus.

Without the help of the turbine, a 2.0L naturally aspirated engine can output 225 horsepower, which is amazing. On the one hand, enterprises no longer need to research and develop the maximum horsepower data of naturally aspirated engines. After all, there are mature turbines to choose from. On the other hand, the playing method like Honda is not suitable for the current environment. After all, the industry emission standards and fuel consumption data will not meet the standards. Technology is a difficult problem. Another problem is that the industry no longer needs such a cranky naturally aspirated engine.

The 3 cylinder outboard rotates at 5000 rpm and the propeller rotates at 1500 rpm. For 82KW diesel engine, the main engine speed is 1500 rpm, and the propeller speed is 500 rpm. The higher the speed is, the better it is. It depends on the output power of the engine and the structure of the propeller. The speed of the engine is related to the number of work done per unit time or the effective power of the outboard engine , that is , the effective power of the engine changes with the speed . Therefore , when the effective power of the engine is stated, its corresponding speed must be indicated at the same time.
