MERCURY ALTERNATOR 821663A1
Description
MERCURY ALTERNATOR 821663A1
The alternator is the fundamental component of the charging system in Mercury marine engines. This 12-volt, 50-amp model provides the electrical power needed to keep the battery charged during engine operation and power all of the boat's electrical systems. It is compatible with 3.0-liter Mercury engines in 200 and 225 hp versions, both in carburetor configuration and in EFI (electronic fuel injection) systems.
The reliability of this alternator is critical to ensure the continued operation of vital systems such as ignition, starting and navigation. A faulty alternator can render your boat inoperable within minutes once the battery charge is depleted.
