Does anyone have any pics of the holes people drilled into the bilge area to drain water from the liner ?
Thanks

Why drain? You are only moving the odor where you cannot get to it

By increasing the flow and exposure of air under the liner it will increase the bilge odor. Water gets trapped in the stringer and not all flows to the bilge area but the air that is in contact with this stagnant water will ventilate more freely out of the larger holes. Give credit to the boat designers when they maintain a sealed liner in the bilge and only use small holes to connect compartments. Let me tell you that dry land stinks but we are so used to it that we do not sense it and consider it the standard. Some boats smell more funkier than others depending on the combination of smells, a little spill of diesel fuel, an oil leak, some mold, permeated sanitary hoses and stagnant water plus whatever could be in the trash. The good news is that after three days at sea you should get used to it and not sense any offensive odors.

I have the same boat with the same issue. Through a long process of elimination, I've become convinced that the odor is coming from between the hull and liner just forward of the shower pan. The floor of the vanity is a raised portion of the liner. My next step is to drill there with a 6" hole saw, clean out the space and install a deck plate. I will post what I find in just a few weeks.

I also have narrowed down the smell to that area under the liner. I would appreciate seeing your photos after you're done.

Yes, me too. Are there any plans or drawings anywhere that show the positions of the inner liner so as we can figure out where to drill?

Did you get a chance to cut out your liner, and install an access port? Just wondering if you were making any progress with the smell. I'm getting geared up tomorrow to high pressure/shop vac my limber holes in my liner/bilge.
