I ran my motor in the test tank today and it was not pumping any cooling water. I pulled the lower unit off and checked out the water pump. As you can see in the photo the impeller on the right is a little bit shorter than the new one on the left.
I also made a few adjustments to the throttle linkage and changed a faulty kill switch. When I put the motor back in the tank everything worked good. Now I need some nice weather so I can finish up the boat.
