Propeller Replacement-Standard Gearcase - Mercury 40 CT Maintenance And Installation Manual

Each anode requires periodic inspection, especially in saltwater which will
accelerate the erosion. To maintain this corrosion protection, always replace
the anode before it is completely eroded. Never paint or apply a protective
coating on the anode, as this will reduce effectiveness of the anode.
This model has an anode installed on each side of the gearcase and one on
the bottom of the transom bracket assembly.

Rotating the propeller shaft may cause the engine to crank over and start. To
prevent this type of accidental engine starting and possible serious injury
caused from being struck by a rotating propeller, always turn the ignition key
or lanyard stop switch to the "OFF" position and remove the spark plug leads
from the spark plugs while servicing.
1. Shift the outboard to the neutral ("N") position.
