After clearing all the external hoses and ports and replacing the impeller with plenty of water pressure to the intake, I still have no tell tale. The pump casing looked fine. Should I install a whole new pump kit instead of just the impeller? What/where should I check next?

If there is no tell tale after replacing the impeller on a Mercury 9.9 EH outboard motor, the next step is to flush the internal water passages with fresh water to check for clogs or blockages that may be preventing water flow.
