A popular alternator model, the 140-amp Cruiser-Series marine alternator is a superior choice for applications with 500 to 600 amp hours of house battery capacity and 6-groove serpentine or dual 1/2” V-belts. This alternator delivers up to 115 amps while on the hook and exceeds its rating at cruising rpm.

While it can be controlled by its built-in 14.1-volt single-stage voltage regulator, or external voltage regulators like Mastervolt’s Alpha Pro or Balmar’s Max Charge models, we recommend our intelligent, multi-stage E-MAAX charge controller for superior charging control. For use on engines with a 3.15” saddle-style mount.
