Too Much Poopy
Greg, Just went through that last season on my 45f5. Seams Beneteau used a holding tank material that rotted where the speed nut fit on the holding tank. Holding tanks could only be punped out half way because of the air leak that eliminated the vacuum. My OEM location is under the forward bed on the Starboard side. The second is in the port lazurette. To eliminated odors which will stay in typical hose for the head, RUN AS MUCH PVC AS YOU CAN. Can you use the LectraSan type systems in CA. They take up less space but the cost is $795ea. I know that one unit can handle two heads. Good luck and don't wait till it's over 90 degrees......it's a nasty job!!!
