Our 35-2 is similar, even with new hoses and a clean tank. Much of the smell is from organisms in salt water decomposing, as it occurs even when the holding tank is empty. I've been told that adding over sized venting for the holding tank will help, to reduce the anaerobic bacteria which is causing the smell due to lack of oxygen. This is on my list.
I suggest flushing some water into your vent line(s) from the outside to ensure they are not plugged. In our case, the tank vent is tied into the anti-siphon (upside-down U) on the bowl flush line, so when flushing, some air is being drawn from the tank instead of outside, causing the smell. I plan to add a separate vent for the head flush line to prevent this. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Wed, Oct 2, 2019 at 11:59 AM Jeff Helsdingen via CnC-List < cnc-list@cnc-list.com> wrote: > Even the good read expensive hose smells bad after a while.
