Problem fixed: Water pump not pumping water through coolant system

Drained oil from lower unit, removed lower unit, removed old pump & gaskets, cleaned & inspected all mating surfaces. Reassembled pump to the recommended torque requirements. Let the exhaust dam of RTV sealant cure for 24 hours. Run motor to test for functionality. Working great. Lets go fishing!
