Replacement Boat Ignition Switches

The ignition switch on a boat is what gets your adventure started — so make sure it starts smoothly with the right components from Marine Parts Source. We offer outboard marine ignition switches that meet or exceed OEM performance, ensuring your ignition system is ready to run on command. Manufacturers like Sierra and Johnson/Evinrude supply boat manufacturers worldwide, so you know you’re getting a premium boat ignition switch.

You’ll find a switch in our catalog that forms a strong wire connection while resisting corrosion and shorts. The standard three-position replacement boat ignition switch has Off, Start and Run modes; it can be purchased with or without a push-to-choke function. A four-position switch adds an accessory mode to run sound systems, navigation and other features without starting the engine. With multiple warehouses across the U.S., there is a boat ignition switch nearby that will arrive fast. Our support team is available by phone and email to help you find the right parts.
