Fuses - Mercury MerCruiser Service Manual

Electrical Components
If the circuit breaker is of the push‑button style, the circuit breaker can be reset by pushing in on the red button.

Fuses

IMPORTANT: When replacing fuses, always use the same style and current rating as the fuse being replaced.
• Fuses of a different style may not operate correctly, providing insufficient circuit protection.
• Fuses with a lower current rating will result in nuisance open circuits.
• Fuses with a higher current rating will not protect the circuit and components from overload.
Engine and Oxygen Sensor Fuses
All of the engine protection fuses are located at the front of the engine. To access the fuses, disengage the fuse holders from
the electrical plate assembly.
