I used muffs with the garden hose ..
Has always worked before when I run before each season
Not the correct way to test a new pump?
I did notice some water coming out of the exhaust by propeller
I have a 94 Mariner Magnum 40HP, serial 0G138021 with water flo issue
I replaced impeller with a complete kit, but still no flow out of motor.
At a loss of whats next to try... Any help is appreciated
