If it is truly plumbed for De-Ice, then at some point in time, the boots were removed. Assuming the entire system is fine, getting them put back on is about $14K.
It is my understanding that some 337's came from the factory with "partial plumbing." It is relatively simple to add boots to these airplanes as long as you are willing to write the check. On 337's without partial plumbing, it is a pretty big deal, and probably cost prohibitive.
