Question:

engine doesnt pump water?

my marine engine doesnt pump water can you tell me some faults can be thanks vic

Answer:

Depends on what engine and what pump check the impeller to see if it is bad.
There are 2 water pumps. One in the stern drive, or mounted on the engine which takes the water your in to cool the engine. The other is a conventional circulating water pump, which is important in fresh water cooled engines . Most often it's the impeller failure.
Check d suction line 4 any chokes, prime d pump if necessary, check discharge line 4 any chokes, And it depends where u have kept the pump...if it is below d head, ur pump may nt pump bcz it might nt have dat capacity to take suction. Also check d impeller and the glands bcz if it is a priming p/p and the glands leak, u will not be able to prime as the water will leak thru the glands.... Hope dis will help u out
year, make and model. regardless of what it is, most likely answer is the impeller has failed completely because it was not serviced regularly as it should of been. if you were out motoring around and it stalled out before you noticed it, you overheated the engine and it probably needs work for it to run again, if its even repairable. outboard the impeller is located just on top of the lower unit. pretty simple to change, but the exact procedure varies depending on year, make and model. sterndrives can be very similiar and just as easy, or different and even easier. depends on year, make and model. inboards the impeller is belt driven. look for the part dirven by the engine belt(s) with two hoses attached, probably down low on one side.
