What is the function of a boat's throttle?

The function of a boat's throttle is to control the engine's power and speed. When the throttle is adjusted, it regulates the flow of fuel to the engine, thereby increasing or decreasing the engine's output. This directly impacts how fast the boat can move through the water and how efficiently it operates. By managing the throttle, the operator can ensure that the boat maintains the desired speed for safe navigation or adjusts it based on cargo, weather conditions, or other factors affecting the journey. Understanding the throttle's role is essential for safe and effective boating, as it allows the operator to respond dynamically to changing conditions on the water.
