I had the same problem with my new-to-me boat. The odor was so bad that when I left the boat I could taste it in my mouth. Yekkh! I junked all the waste hose and replaced it with new odorfree hose (the $9/ft variety). The boat still stunk until the old hose was physically out of the boat, then it was a pleasure to be in the boat. When I removed the old hose, petrified fecal matter fell out in little chips.
Yes, I knew you wanted to know that.
This stuff that sticks to the inside of the hose is the source of most head-related odors, IMHO.
