Marine alternators
High-output marine alternators and OEM replacements. For boats with large lithium house banks (1,000Ah and up), an upgraded high-output alternator pays for itself in dramatically faster recharge times underway. Marine Electric Systems specifies the Arco 275A for most lithium refits.
- ARCO 175A, 250A, 275A high-output alternators — designed for lithium charging
- OEM-replacement alternators — direct fit for Yanmar, Volvo Penta, Cummins, Westerbeke, and other marine engines
- Stators, rectifiers, brush kits — OEM rebuild components
High-output alternators require external regulation — see ARCO Marine for the Arco Zeus regulator. For complete installation including conversion, current shunts, and Victron Cerbo GX integration, see our high-output marine alternators service page and our companion piece on the Arco Zeus + Victron integration. Marine Electric Systems serves Annapolis, Baltimore, and the Washington DC area.
