This labor day weekend, I made the decision to remove the full head system in our hunter / cherubini 27. The toilet, bladder tank, hoses, whale gusher pump and diverter....all out! I have read that the hoses begin to smell after a few years anyway. I am installing a porta potti system. The longest we would stay on the boat would be a couple of days. The boat has been rid of the the old system for about 6 hours and now smells much better!
