Does anyone know where the access hatch is to view the hose connections for the aft head holding tank? I found the tank is located in the area behind the galley settee and refrigerator but I cannot see the hose connections.

I have the same boat and replaced both tanks and hoses this spring. The aft cabin holding tank is behind and below the refrigerator. if you remove the floor from the closet behind the fridge you will see the top of the tank and the hose fittings. You need to remove the aft wall of that cabinet to see the hoses and where they connect to the deck fittings. Let me know if you need any other info on this project. not that bad to do. i had holes in both of the original aluminum tanks and yes it was not a nice smell.

Thanks for the advice and sorry for the slow response. I've been enjoying the boat and haven't been on the site for quite sometime. I actually did stumble upon the access on my own. The job wasn't that difficult once you figured out how to access it, although this is not a job I look forward to doing too often...I guess I should do some preventative maintenance and change out the other holing tank befor it begins to leak. The forward head holding tank seems like it would be a simpler job as far as access. On another note, have you ever had any issues with your windlass? My windlass is getting power, you can hear what sounds like a relay operate, however that's it. I thought the brushes in the motor might be worn or the motor it self, but I am having troubles figuring out how to remove it, any suggestions?

Any photos of the tank and hoses replacement project?
I have removed many of the panels in the storage area behind the refrigerator, see a good amount of the lines but many do run through the midship firewall in engine room. Any pictures or info on how best to access the septic lines from head to tank would be awesome.

The hose that runs through the engine compartment is easy to get at. It runs on top of the outside stringer between the fore and aft bulkheads. I haven't tried to access the tank yet but from what I can see, I suspect you have to remove the closet floor behind the fridge. I'd probably remove the fridge also to get access from a lower point. I imagine the the hose to the deck fitting runs behind the starboard wall in the closet. The hose from the port tank will be there too. If you tackle this, pics would be nice.

Are you doing this because of a tank leak, sender problem, or replacing hoses? I'll have to do this eventually as I'm planning to replace the hoses and switch to a Vacuflush.

Any more info on this? Tank in engine room is leaking. Is that the tank for the forward head? Any ideas on where to get a replacement?

If you're talking abut the tank in front of the port engine, that's the tank for the forward head. There should be enough room to pull it out by sliding it to the middle of the bilge, swing it so that it faces fore and aft, then take it out through the center hatch section. You may have to remove the light fixture on the bulkhead and the center aluminum support to give you more room when pulling it out.

Does anyone know how to tell when it is time for pump out on the 3807?

The use of Vicks Vapor Rub under ones nose while preforming these stinky jobs helps a lot. Big-Boat you'll have to look or count the flushes to know when it time to pump out, or put in tank monitors!
