Water pump basics

John asked on 6/4/2019 5:27:26 AM
After replacing Johnson 15hp water pump the telltale does not squirt water. Iíve troubleshot the seal, intake line is clear and have assembled unit three times without success. Not sure mechanically how the impeller can spin while in neutral? The shaft impeller pin drives the impeller but only while in gear. Was told the telltale should eject water immediately after starting.

What am I missing?
