stainless steel plug for 470/MCM 165/3.7L

Hey.
Number 4 spark plug is rusting. I need a stainless steel equivalent for a Champion RV9YC. Can't find any cross reference online. Local shop was no help.

Any ideas?
Thanks,
Nate

Ayuh,... Why is only #4 rusting,..??

AC Delco marine sparkplugs are alloy bodies...

Salt spray drips down from the hinge area of the dog house onto the engine in that area. After each outing, I rinse with fresh water. When that dries, I spray with Quicksilver Anti-Corrosion Spray, but the plug is still rusting.

Is there a cross reference from the Champion plug I mentioned to the AC Delco marine plug?

In other words, every time I go to a manufacturer's website and go through the application guide, I get referred to a standard (rustable) spark plug.
