# ARCO Marine Mercury/Mariner Outboard Starter - 10 Tooth [5375]

**Mercury/Mariner Outboard Starter - 10 Tooth**

The outboard starter will fit Mercury /Mariner, 50-90 HP/65 HP Jet, and 10-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 
-   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.
