ARCO have set the gold standard for marine engine parts for more than sixty years and are recognized globally as a leading manufacturer of high quality and reliable parts. 

The main reason why should you should buy a Marine Starter VS an Automotive Starter is safety. A marine starter or alternator is designed to contain sparks that could ignite fuel vapor in your bilge or under your motor cover where fumes exist. Without an approved Marine starter or alternator any stray spark could cause an explosion & you don’t want that happening when you’re out on the water. Other benefits include anti-corrosion properties and additional seals and gaskets to keep moisture out & lengthen the products life.
