Will this fit my Mercury outboard motor?

How durable is this ignition switch in marine conditions?

The body is molded from marine-grade glass-filled polyester to resist moisture, salt and UV exposure while the non-conductive housing lowers the chance of electrical shorts. The pushbutton choke design reduces exposed moving metal, improving long-term corrosion resistance compared with many exposed rotary assemblies.

• Marine-grade glass-filled polyester housing for corrosion resistance.
• Non-conductive casing reduces risk of short circuits.
• Push-choke mechanism with concealed contacts for added protection.
• Designed for repeated use at 30 A / 12 V electrical loads.
