ARCO Standard Duty Inboard Starter with Gear Reduction

The ARCO Inboard Starter (Mercruiser, Volvo Penta, OMC, Marine Power, and other GM engines with a 14 in flywheel and staggered bolt pattern) is dynamically tested and packaged for out-of-the-box performance. Recommended for late model 3.0 liter engines with a 14 in flywheel using a tail bracket, and can also replace a 10MZT style starter with two long bolt staggered patterns. Mounting bolt kit MBK450 is required if replacing a 10MT starter. It is designed for boaters who want nickel-coated and/or epoxy-painted construction to reduce corrosion, sealed to minimize water intrusion.

ARCO advises using a fully charged battery, since a weak battery can damage the starter and starter solenoid, and cleaning all connections regularly, as a corroded connection creates resistance and lowers the amperage required for an efficient starting circuit. Armatures are tested to withstand 50 times operating voltage (12 volts), backed by ARCO's warranty against defects in materials and workmanship for 12 months of leisure use (90 days for commercial or racing applications).
