Solutions 
Solution 1: Remove debris in impeller. (Do not remove impeller)
Solution 2: Check suction hose. Most cases of lack of priming 
or low water flow are caused by air leakage on the suction 
side of the pump.
Suction test:
a.   Remove suction hose
b.   Start engine with water inside the pump.
c.   Press the palm of your hand to cover the suction inlet, 
hold and wait 30 seconds. If you feel suction on your 
palm, the pump is working fine. Check suction hose 
and connections.
d.   Check if rubber seal is installed.
Note: In case of water 
leakage between 
engine and pump, 
usually the cause is 
damaged mechani-
cal seal. Please ask 
shop for assistance 
and replace me-
chanical seal.
