replaced one themostat, disconected lower unit twice look at the water pump everything looks fine but when lower unit was reconnected water pump would not work. not sure if asembled it wrong or forgot to d somthing. can someone help.
check the water tube conection to make sure it is lined up and check to make sure the key is not sheered or missing from the water pump impeller
im guessing the impeller (in a count of a pair days off) went undesirable, that's unlikely, not probable all that unlikely. how previous replaced into it? are you interior the habit of cranking the motor without water attached? the two holes are exhaust alleviation ports -- their functionality is to alleviate stress to facilitate beginning, which might somewhat be made complicated by means of backpressure on the underwater exhaust. various the water comes out down by means of the decrease unit, even though that's common to work out water popping out those ports.
You miss aligned the Pick UP tube with the lower unit, drop the unit, and watch from the bottom to make sure the hose hits the PICK UP tube !
if all is lined up properly use compressed air and blow through the visual. this will dislodge any debris that may be blocking the water passages.
