Also going to paint the bilge and the floor. I am concerned now ( since the smell has worsened) that all the head liners ect must come out. Has anyone been thru this before? I would love some advice.

Our 1990 calif hadall the old boat smells.First I cleaned all the bilges with a mix of bleach and Whisk administered with a one gallon sprayer, several times. Remove panels leading to the hull and spray there as well.
Replaced and tightened all head lines. Re-sealed the access port into black tank after scooping 25 years of raw water flush sediment out. Changed heads to fresh water flush.
Every opportunity I get I open up the bilges and ventilate with fans and open windows. This REALLY helps.
It's pretty good after 6 months of all the above several times
