Protection Guide.
Typical single sterndrive
a - Anode (Alpha models), MerCathode (Bravo models)
b - Ventilation plate anode
c - Trim cylinder anodes
d - Bearing carrier anodes
e - Gearcase anodic plate
f - Anode kit on hull (if equipped)
Dual sterndrive
a - Anode (Alpha models), MerCathode (Bravo models)
b - Ventilation plate anode
c - Trim cylinder anodes
d - Bearing carrier anodes
e - Gearcase anodic plate
