Alan Theriault
May 18, 2025

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.

  • Page 29: Lanyard Stop Switch

    GENERAL INFORMATION Lanyard Stop Switch The purpose of a lanyard stop switch is to turn off the engine when the operator moves far enough away from the operator's position (as in accidental ejection from the operator's position) to activate the switch. Tiller handle outboards and some remote control units are equipped with a lanyard stop switch.
  • Page 30 GENERAL INFORMATION Important Safety Information: The purpose of a lanyard stop switch is to stop the engine when the operator moves far enough away from the operator's position to activate the switch. This would occur if the operator accidentally falls overboard or moves within the boat a sufficient distance from the operator's position.

  • Page 31: Protecting People In The Water

    GENERAL INFORMATION Accidental or unintended activation of the switch during normal operation is also a possibility. This could cause any, or all, of the following potentially hazardous situations: • Occupants could be thrown forward due to unexpected loss of forward motion ‑ a particular concern for passengers in the front of the boat who could be ejected over the bow and possibly struck by the gearcase or propeller.

  • Page 32: Passenger Safety Message - Pontoon Boats And Deck Boats
