Frequently Asked Questions

Q: Is this ignition starter switch compatible with Mercury and Mariner outboard motors?

A: Yes, this 12V 3-way ignition starter switch is specifically designed to fit Mariner and Mercury outboard motors. It also works as a universal replacement for most ignition switches with similar mounting dimensions, including those on boats, trucks, tractors, and other outdoor equipment.

Q: What is the "push-to-choke" feature and how does it work?

A: The push-to-choke function allows you to activate the electric choke simply by pushing the ignition key inward before turning it. This enriches the fuel mixture for easier cold-weather or cold-engine starts without needing a separate choke control.

Q: What mounting hole size is required to install this switch?

A: This switch requires a standard 7/8" (approximately 22mm) mounting hole, which is a common size for marine dashboards and control panels. Always verify your panel's existing cut-out size before installation.

Q: What materials is this switch made from?

A: The switch is constructed from ABS plastic housing, brass with chrome plating, and stainless steel components. This combination provides excellent corrosion resistance and durability in marine and outdoor environments.
