ARCO High-Performance Marine Inboard Starter – PMGR Clockwise | MPN: 70125
Ensure rapid, reliable engine ignition in demanding marine environments with the ARCO High-Performance Marine Inboard Starter (Part Number: 70125). Utilizing advanced Permanent Magnet Gear Reduction (PMGR) technology, this heavy-duty 12-volt starter delivers maximum cranking torque to turn over high-compression marine V8 engines while drawing substantially less current from your battery bank than legacy direct-drive units.
Engineered specifically for late-model marine inboard and sterndrive applications with Clockwise (CW) rotation, the ARCO 70125 features an epoxy-painted, corrosion-resistant housing and precision-sealed internal components to block out moisture and salt air. Every unit undergoes rigorous dynamic testing and armature insulation voltage checks up to 50 times operating capacity, providing out-of-the-box reliability when you turn the key.
Key Features & Performance Advantages
-
Permanent Magnet Gear Reduction (PMGR): Multiplies torque output while lowering electrical resistance and amp draw on your starting battery.
-
Corrosion-Resistant Marine Coating: Finished with heavy-duty epoxy paint and nickel-coated hardware to resist oxidation, salt spray, and bilge moisture.
-
Sealed Marine Design: Internal seals minimize water intrusion and prevent internal arcing in damp engine compartments.
-
100% Dynamically Tested: Factory-tested under loaded conditions to guarantee performance, torque output, and solenoid engagement prior to packaging.
-
Direct OEM Drop-In Fit: Designed for seamless bolt-on replacement on late-model Ford 5.0L and 5.8L marine V8 engines, OMC/BRP, and Volvo Penta applications.

Frequently Asked Questions (FAQ)
Q: What is the benefit of a Permanent Magnet Gear Reduction (PMGR) starter over an older direct-drive starter?
A: PMGR starters use internal planetary gear sets that spin faster and produce much higher cranking torque while requiring a smaller footprint and significantly lower amp draw from your starting battery.
Q: How do I verify if my engine requires a Clockwise (CW) or Counter-Clockwise (CCW) starter?
A: Starter rotation is always determined by looking directly at the fly-wheel drive pinion end of the starter motor. The ARCO 70125 is engineered for Clockwise (CW) rotation setups.
Q: Can a weak or undercharged battery damage a new starter?
A: Yes! Operating a starter with low battery voltage causes high amperage draw across the solenoid contacts, which can pit or weld the internal connections. Always ensure your battery is fully charged and all cable terminals are clean before installation.
