    High-Performance Inboard Starter with 14" Flywheel & Gear Reduction

    The inboard starter that will fit Mercruiser, Volvo Penta, OMC, Marine Power, and others. Will replace 9 tooth drive OEM versions 3.0 - 8.1L with 14" flywheel. Anodized casting, nickel-plated brush holder (OEM mounting bolts included).

    ARCO advises using a fully charged battery - A weak battery can damage the starter and starter solenoid. And to also clean all connections - A corroded connection creates resistance, lowering the amperage required for an efficient starting circuit.

    Features:

    • Dynamically tested and packaged for out-of-the-box performance
    • Nickel-coated and/or epoxy-painted to reduce corrosion 
    • Sealed to minimize water intrusion
    • Designed for long life and optimum performance
    • Armatures are tested to withstand 50 times operating voltages (12 volts)

    Warranty Information:

    When properly installed, all ARCO products are warrantied against defects in materials and workmanship for a period of 12 months for leisure use and 90 days for commercial or racing applications. 

    Add an extra year of warranty to your rotating electric ARCO product (Tilt/Trim Motors, Alternators, Outboard Starters, and Inboard Starters) when you register your product within 30 days of purchase. You can register your product by visiting arcomarine.com/product-registration
