Clearing A Lodged Impeller; Pre-Starting Instructions - Mercury 25 Jet 4-Stroke Manual

Clearing A Lodged Impeller

If the flywheel is rotated to free a lodged impeller, there is the
possibility that the engine will crank over and start. To prevent
this type of accidental engine starting and possible serious injury,
always turn the ignition key or lanyard stop switch to the "OFF"
position and remove all spark plug leads from the spark plugs.
It is possible for debris to lodge between the impeller and jet
housing wall, especially after the engine has been stopped. This
will lock the driveshaft and will prevent the engine from being able
to crank over for starting. Following are steps for dislodging the
impeller.
1. Position lanyard stop switch to the "OFF" position.
2. Remove spark plug leads to prevent the engine from
accidentally starting.
3. Remove flywheel or rewind cover and rotate the engine
flywheel counterclockwise.
If this does not dislodge the impeller, it will be necessary to remove
the six screws and water intake housing.
Pre‑Starting Instructions
1. Connect the remote fuel line to the outboard. Ensure the
connector is snapped into place.
