If an operating bilge pump is developing good vacuum, but is unable to discharge any water, which of the following problems is the most probable cause?
AI Explanation
The correct answer is C) The suction strainer is clogged.
If the bilge pump is developing good vacuum but unable to discharge any water, the most probable cause is a clogged suction strainer. A clogged strainer would prevent water from being drawn into the pump, even though the pump itself is functioning properly. The other options - a clogged discharge valve, worn wearing rings, or a worn shaft - would not prevent water from being drawn into the pump in the first place.
Therefore, a clogged suction strainer is the most likely explanation for the described problem with the bilge pump.
