I am new Tiara owner (2003 35 open with twin Cummins) and appreciate the tips and suggestions on the forum.
As I go through the boat I found a dual hose fitting in the aft port corner. One fitting is marked raw water wash down and I have found the rocker switch for that. The other is marked fresh water. Where is the switch to turn that on and off? The owners manual does not locate it either.
Sorry did not read your post properly. Fresh water wash down is operated off the fresh water pumps. As long as your fresh water system is pressurized the wash down will work.
There is no separate switch for it.
