For Engine Models:FM-12-100a
Our 100-amp Cruiser-Series marine alternator is an excellent entry into truly high-output charging performance. Perfect for weekend, or a week-long cruise, the 100A Cruiser will deliver 70 amps at a high idle, and 100+ amps at cruise RPM. This alternator can be driven by a minimum 1/2” single V-belt (we recommend using a cogged V-belt like Dayco’s “Top Cog” for better power transfer).
The alternator can be controlled by its built-in 14.1-volt single-stage voltage regulator, or with external voltage regulators like Mastervolt’s Alpha Pro or Balmar’s Max Charge models. For safer, faster and more complete charging, we recommend our multi-stage E-MAAX voltage regulator, with the internal regulator kept disconnected as a back-up. For use on engines with a 1” or 2” spindle style alternator mount.
