RE: Forward Waste Tank
I have a 34 ft MT that I am am refurbishing now.* Floor is open*and the holding tank is exposed.* In mine, it is a fiberglass molded tank under the steps leading to the fwd cabin.*All the plumbing to/from the tank comes out in my engine*room*bilge.* *I suspect that you could remove*your floor above it,*cut open the top of the tank , clean it out (awful job), repair the leak and reglass the open area and be good to go.* It doesn't look like an easy tank to take out because it was probably made in place.* Looks pretty thick walled to me.* You can stand on it without flexing it.
I will be working in the boat this weekend, converting the fwd head into a shower.* I*could take a closer look at it.** If you want, I will take a picture giving you a better idea of how it is constructed.
