hi peggie, went to boat today to start removing hoses,don't know which is worse, changing babies diapers or these hoses. the tank in the c34 is mid-ship on port side. read your last reply about adding a thru hull to make a shorter run and vent thru thru hull, but i don't know where to add one. if you have dealt with this model boat before please give me a recommendation. out the side i'm afraid would possibly allow water to enter on a good heel, or out thru deck? also as far as the 11/2" hose, will get best hose,odor safe or trident, but my boat has both white and black hose. any preference? thanks for all the advice,muchly appreciated...jeff
