What must be done to the motor during an inspection?

During an AIS inspection, it is essential to lower the motor to drain any existing water because trapped water can be a significant vector for the spread of Aquatic Invasive Species (AIS). By lowering the motor, inspectors can ensure that any residual water, which could harbor invasive species or their larvae, is removed. This step is crucial for preventing the introduction of AIS into new water bodies and is a best practice in watercraft sanitation.

While it might seem relevant to raise the motor or cover it, these actions do not address the immediate concern of water that might be present. Fully dismantling the motor is excessive and not practical for a standard inspection, as it is neither necessary nor efficient for checking for invasive species concerns. Therefore, draining residual water is the most effective and necessary part of the inspection process.
