Overheating of the hydraulic fluid in an electro-hydraulic anchor windlass can result from a/an __________.

Correct Answer: Option B — low fluid level in the reservoir

Low fluid levels in the reservoir allow air to enter the hydraulic circuit. This aeration causes cavitation and fluid foaming, which significantly reduces the fluid's heat-transfer efficiency. As the pump works harder to compensate for the lack of solid fluid, the system temperature rises rapidly, leading to overheating.
