stainless steel snake?

For that use, a light duty stainless steel snake like this one at "http://www.amazon.com/Flexible-Snake-Drain-Millipede-Cleaning/dp/B008ZUNPEA#productDetails" might work for you. Don't use it for heavy duty clogs.

Cleaning refer coils and general salt water lines can be easily accomplished by using muriatic acid. As it is quite dangerous, On-Off Hull and Bottom Cleaner does nearly as well, much more safely. Route the exhaust hose into the same plastic bucket as the pick up and run the a/c circulation pump (or any pump) for a few minutes once a year and your a/c lines will be clean and work very efficiently. I don't think your snake or a brush will actually remove all the scale on the inside of the coils.

In this situation I believe it was just mud. Once I ran the flexi wire with a brush on it, and reversed the flow, it worked great, and just had dirty water come out. I had thought about a mild acid, maybe even vinegar, but had not a great way to get it thru, other then a funnel on a hose. the pump is mounted 20' away in the engine bilge.

I dont think a snake for a sink would work. the end is too large. I am not sure what this tool is the old owner left on the yacht, but its nearly perfect for the job. Its just flexible wire, with bristles on the ends.
