Mercury/Mariner Outboard Starter - 8 Tooth

The outboard starter will fit Mercury/Mariner, 100-125 HP Inline 4-cyl; 80 HP Jet, 8-tooth drive gear.

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 epoxy-painted to reduce corrosion
