I think the water pump on my 40 hp mercury outboard 2 stroke is not working, the hole witch usually pours out all the water that was used to cool the engine does not pour any water at all. Is this a problem with the water pump? If not what?
requires visual inspection of the water pump. actually, checking the telltale outlet first might be preferable.
Well to start of, and two, A 25 hp does not have a water pump, like a car, it has am impeller driven by the out board motors gear system
Check the water intake is not blocked. Then the water impellor. Then lastly check the water tell tail outlet hole is not blocked/obstructed.
