Description

The inboard starter that will fit Mercruiser, Volvo Penta, OMC, Yamaha, and others. 12-3/4" flywheel. Clockwise Rotation. Will replace all CW rotating 10MT starters with one long and one short bolt straight across the pattern. Includes mounting bolts and gasket. Anodized casting, nickel-plated brush holder.
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
