Marine Alternator 400-40178

94 Amp High Output Conversion for Marine Systems

This high-output marine alternator is a precision-engineered conversion unit based on the reliable Delco 10SI family.

PERFORMANCE UPGRADE: Optimized for marine environments with an external fan for superior cooling and consistent voltage under heavy loads.

Key Features

  • High Output 94A: Superior charging for onboard electronics.
  • Direct Conversion: Drop-in replacement for Valeo units.
  • Marine Sealed: Built for high-moisture environments.
  • Internal Regulator: Simplifies wiring and installation.
