When converting from a gasoline engine power source to an all-electric system, which factor is NOT necessary to consider?

When transitioning from a gasoline engine to an all-electric system, the horsepower of the old gasoline engine is not crucial to consider because electric motors are rated by wattage rather than horsepower. The wattage provides a more direct measure of the power output needed for the new electric system. Consequently, the focus shifts to the compatibility and power needs of the electrical components and the capacity of the batteries which will supply energy to the electric motor.

In contrast, understanding the wattage of the electrical components is essential to ensure that the new system can handle the required loads efficiently. Considering the weight of the new electric motor is also important because it can affect the overall balance and performance of the vessel. Lastly, adequate battery capacity is crucial for determining how much power will be available for operation, influencing range and efficiency. Therefore, while the performance of the old engine might provide some context, it does not directly impact the specific requirements of the new electric system.
