I put in new impeller in my 8hp 2005 Yamaha outboard and I'm still getting no pee. Took off foot and put hose on intake pipe and it is getting good water around sleeve and it is coming out of prop exhaust pretty good. Ran motor for ten minutes with water muffs on and block never got hot. Also took out thermostat. Tried to flush out pee tube with air and water and still no pee...help!
