What is the starter duty cycle for a small craft engine?

The starter duty cycle for a small craft engine is generally defined as the duration the starter motor can operate continuously before it needs to cool down. In this context, the correct choice indicates that the starter can run for 30 seconds followed by a 2-minute rest period. This specification allows the starter motor to avoid overheating, which can occur if it is continuously engaged for too long.

When starting an engine, the starter must exert significant effort, and prolonged use without breaks can lead to thermal damage due to excessive heat generation. Therefore, adhering to the recommended duty cycle ensures that the starter operates efficiently and extends its service life, while also preventing damage to the engine's starting system. This cycle is particularly important for small craft engines that may be subjected to various operational stresses.
