boat marine tachometer wiring diagram

The boat marine's Tachometer line is connected to the generator. The generator W terminal is the sensing output of the Tachometer. The red line is the power line of the Tachometer. Since the clock of the Tachometer needs to work continuously, the red line must be kept powered at all times and can be connected behind the power fuse. There is a 24mm hexagonal bolt plug under the generator of the gear compartment cover. Remove it, facing the camshaft gear, and install the speed sensor directly to measure the speed. Add a DC motor to the main shaft of the engine (such as next to the generator).

High speed boats have an outboard engine, an inner engine spray pump, and a surface propeller. The outer engine has a speed of over 6000 rpm, the spray pump has a speed of over 6500 rpm, and the surface propeller has a speed of over 6000 rpm. Low speed boats with a speed of less than 6000 rpm are not fast boats.

The speed is equal to the pitch x speed of the propeller. It's not that the propeller speed is faster and the ship speed is faster. The relationship between propeller speed and speed is that both propellers have a pitch and the distance traveled by the propeller during one revolution. Therefore, in an ideal state, speed is equal to the pitch x speed of the propeller. So we can change the ship's speed by changing the CPP pitch, but the ideal state does not exist, as the speed is greater than the pitch x speed in the case of wind and water. When facing against the wind or water, the speed may not be certain, and it is likely to be less than the pitch x speed.

The most fuel-efficient is that the slower the speed , the more fuel-efficient it is. However , it is impossible for a speedboat to not increase the throttle just to save fuel. The speed of the external engine of the speedboat is between 6000 to 6200 rpm , and the most fuel-efficient and fast speed is between 4000 to 4200 rpm , which is the speed at which the speedboat just flies on the water. You can tell me what brand of machine, what horsepower of machine, and how much oil can be burned in an hour at what speed.
