mercury outboard tachometer settings

About the mercury outboard tachometer settings , it is divided into three steps, as follows:

1. Turn on the settings first, and then find the 'comfort function' - 'mirror adjustment', and then monotonous and synchronous adjustment will appear.
 2. As for the display mode of 'average fuel consumption' and 'long-term fuel consumption', press the function key next to the steering wheel to find the 'average fuel consumption' display, and then press the 'OK' key in the middle to display the 'long-term fuel consumption'.
 3. Press the multi-function key on the right side of the steering wheel to find the display of the driving time, and then press the OK key in the middle. The words "long time" will appear, so that the Mercury outboard tachometer setting is complete.

The signal measured by the tachometer is frequency, and the unit is HZ, that is, "pulse/S". To convert it to "revolution/min", first convert S to minutes, and then change the scale factor to 60, so that the corresponding unit of the displayed value is "pulse/min". Then look at the number of pulses per revolution, and divide the scale factor by several. For example, now there is a device with 30 pulses per revolution. If the meter displays "rpm", set the scale factor to 2 (scale factor=1 * 60/pulses per revolution).

The idle speed adjustment steps of Mercury outboard engine are as follows: 1. Start Mercury 3.3 outboard engine and preheat for 3-5 minutes. 2. Mercury outboard fully resets the choke valve of the outboard electromechanical spray. 3. Tighten the idle speed limit screw to 1500 rpm and 2000 rpm. 4. Slowly screw the mixture adjusting screw in or out from the left to the right until the engine speed is the highest and the operation is the most stable. 5. Adjust the idle screw to 1000 rpm and 1300 rpm. The speed range of the propeller of the Mercury outboard plug-in engine is 5250-6250. The propeller of Mercury external store is a propeller composed of a propeller hub and a number of blades fixed radially on the hub, commonly known as a vehicle blade. The propeller is installed below the stern waterline, and the main engine (see the outboard engine power device) gets the power to rotate. After pushing the water to the ship, it uses the reaction force of the water to push the ship forward. The propeller has simple structure, light weight, high efficiency and is protected below the waterline.
