As part of the pre-lowering check for a motorized lifeboat, you should do which of the following?

Correct Answer: Option D — Both A and C

Pre-lowering checks are mandatory under SOLAS and 46 CFR to ensure survival craft readiness. Verifying the boat plug prevents flooding, while ensuring the start air system is pressurized guarantees the engine can be started immediately upon reaching the water, which is essential for clearing the vessel's side during an emergency.
