Arco Starting & Charging: Marine Engine Parts Built to Outlast the Elements
When a marine engine fails to turn over in the middle of open water, the quality of the starting and charging components on board becomes immediately apparent. Arco Starting & Charging has spent decades earning a reputation as one of the most dependable names in marine engine electrical components — and their presence in the Engine Parts & Accessories category reflects exactly that legacy.
Arco is a manufacturer, full-service provider, and distributor of new OEM products and remanufactured electrical components for the starting and charging systems of marine engines, having opened its doors in 1960. That depth of experience translates directly into the engine parts and accessories they produce today.
Engineering for the Marine Environment
What separates Arco engine parts from generic alternatives is a rigorous approach to corrosion protection and performance validation — two factors that matter enormously in saltwater and freshwater boating environments. Arco boat starters are designed and manufactured with corrosion protection in mind, featuring nickel-plated armature shafts fitted with silicon-laminated steel stacks, with an added layer of powder coating for better insulation and corrosion prevention.
The quality control process goes beyond surface treatments. Motor shafts are induction case-hardened at bearing surfaces for superior wear resistance, all armatures are tested to withstand 50 times the operating voltage, all motors are performance tested at five different load levels, and every motor must meet or exceed OEM performance before being boxed.
A Broad Engine Parts Portfolio
Arco is the trusted source for OEM quality or better alternators, inboard starters, outboard starters, and tilt/trim motors. Their outboard starter lineup covers a wide range of engines and manufacturers — including Chrysler/Force, Honda, Johnson/Evinrude, MerCruiser, Mercury/Mariner, OMC, Suzuki, Volvo Penta, and Yamaha. For inboard applications, heavy-duty 12-volt starters are available for platforms such as MerCruiser 302 and 351 Ford-based engines, delivering reliable cranking power for high-compression marine powerplants.
On the alternator side, Arco offers marine-grade units including 12V, 70-amp designs with internal regulators engineered for marine use. Their premium ARCO Zeus line takes charging performance even further: the Zeus collection of high-energy products is purpose-built to charge batteries faster and optimize alternator output, including the Zeus alternator regulator and 12V, 24V, and 48V Zeus alternators.
Made and Tested in the USA
ARCO Marine manufactures, quality-tests, and warehouses parts right here in the USA. That domestic production gives the brand tight control over consistency and inventory. Team ARCO is comprised of industry leaders and experts with decades of experience building — and improving — rotating electrical parts.
Backing their products is the ARCO Assurance Warranty Program. When properly installed, all ARCO products are warranted against defects in materials and workmanship for 12 months for leisure use and 90 days for commercial or racing applications, with an extra year of warranty available on rotating electric products when registered within 30 days of purchase.
For boaters and marine technicians who depend on their engines starting every time, Arco Starting & Charging engine parts represent a proven, American-made solution that meets or exceeds the demands of the original equipment they replace.
