Corrosion Control Anode; Propeller Replacement - Mercury 135 Verado Manual

Corrosion Control Anode

The outboard has corrosion control anodes at different locations.
An anode helps protect the outboard against galvanic corrosion by
sacrificing its metal to be slowly eroded instead of the outboard
metals.
Each anode requires periodic inspection, especially in salt water
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.
Two anodes are located on each side of the gearcase. Another
anode is installed on the bottom of the transom bracket assembly.

Propeller Replacement

1. Shift outboard to neutral position.
2. Straighten the bent tabs on the propeller nut retainer.
