outboard tachometer application chart

• 2023-03-01

Our tachometer can be used on outboard. Also can be used on marine , boat , yacht , vehicles and so on. For example , Yamaha 242 jet boat consumes a lot of fuel. Yamaha 242 jet boat, equipped with two 1.8 naturally aspirated 4-stroke 4-cylinder engines, multi-function LCD touch screen, tachometer, depth/speed measurement function, Connext joystick, 8 loudspeakers, electric bilge pump, engine room blower, 12V socket, supporting USB/AUX/Bluetooth output, front and rear water ladders, retractable sculling rack, sunshade, sculling hook, removable table, rear diving board&volume control panel, large storage space, Two garbage cleaning pump ports, 190L oil tank, and the full speed of two engines can reach more than 40 knots.

Such as , the speed of the outboard is 120 mph and 2200 rpm. Because the outboard engine speed is 700 rpm, the engine noise can hardly be heard in the car. It can be seen that the engine noise control is relatively good; When driving at a constant speed of 120 yards on the highway, the engine speed is about 2200, so the speed of the wind yacht is 120 miles and 2200.

Many people have the question, what is the outboard tachometer for?? The higher the better? The higher the number on the tachometer, the higher the speed of the car? Or start fast? Vehicles and ships have tachometer, speedometer, etc. The tachometer displays the engine speed, which is the most intuitive function for the driver to determine when to shift. During acceleration, the speed keeps rising. When it reaches a certain speed, such as 3000 rpm, it can be upshifted - you can not raise it, and the fuel consumption will be very high. When the throttle is released, the speed will continue to decrease. When the speed is reduced to a certain speed, such as 1500 rpm, the gear can be downshifted - you can not reduce the speed, and the engine will be choked down if the speed is lower. At idle speed, it is about 1000. The lack of use in the movie is the reason why the speed of the crankshaft and the tachometer do not match. Like ordinary cars, it is difficult to reach the theoretical value of the tachometer. When starting, it should be combined with gear. When doing work, the car should accelerate or start fast or slow according to the intake water temperature and speed. We should also consider some correction signals to achieve better results.
