Product Details

The Arco Starting & Charging SW109 is a heavy-duty marine solenoid specifically designed for Mercury and Mercruiser engine applications. This reliable solenoid serves as the critical switching component in your marine starting system, controlling high-current flow from the battery to the starter motor.

Key Features:

  • 12-volt operation for standard marine electrical systems
  • Isolated base design prevents unwanted ground connections and electrical interference
  • Direct replacement for Mercury and Mercruiser OEM solenoids
  • Corrosion-resistant construction for harsh marine environments
  • High-current switching capability for reliable starting performance

The isolated base configuration makes this solenoid ideal for applications where mounting flexibility is needed or where electrical isolation from the mounting surface is required. Arco Marine is a trusted name in marine electrical components, offering quality replacement parts that meet or exceed OEM specifications.

Thanks

So far so good

Very simple to order. Very best price I could find in the USA

Grate

The ordering process was easy and the price of the product was fair. I was; however, disappointed with one thing. I received an email from Autoplicity for 25% off shipping but it would not work when I was checking out. I called the customer service number and the gentleman was not helpful at all.

just fine, appreciate your free services I am unable to tell if I am satisfied with product as of yet.. wwait till I pull all my hair out and I will tell you..

great
