The first check would be to ensure that the tell tale hose is open. Dirt daubers are notorious for crawling up in the hose to build their nest. If you have access to an air compressor, try shooting a short blast of air through the hose. Another method that works is to slide a short length of wire up the hose, in an attempt to unplug it. If the hose is not clogged, the lower unit should be removed for further diagnosis. Make sure that the water tube seal, located in the pump housing, is serviceable. Sometimes when the foot is installed, the tube is not properly inserted, or missed altogether. While the foot is off, blow air, or run water through the water tube to insure that there are no other blockages.

How does an outboard motor water pump work?
An outboard motor water pump operates by drawing water from the body of water in which the boat is submerged. As the engine runs, the pump's impeller spins, creating a vacuum that pulls water into the pump housing. The impeller then forces the water through the cooling system, circulating it to cool the engine and expel excess water through the exhaust. This continuous flow prevents overheating and ensures the engine operates efficiently.
How do you tell if water pump is working on outboard engine?
To determine if the water pump on an outboard engine is working, check for a steady stream of water exiting the telltale (the small outlet typically located on the side of the engine). If there is no stream or it is weak, the pump may be malfunctioning. Additionally, monitor the engine temperature; if it overheats, this may indicate a cooling issue related to the water pump. Regular maintenance and inspection of the pump and impeller are also essential for ensuring proper function.
