Welcome to JA

what you need to do is remove the outdrive and stick a garden hose up the intake hose and see if your getting water up there

if you just replaced the impeller, the impeller housing could be worn out also

I already did that and can put water down to the pump and from the pump to the lower end. Am waiting for a casing. Don't bother I'll take the boat in and get a local to cure it ... summer wwill soon be over...
