84' 3207 Waste Holding Tank

Not a Carver owner, but I think the tank is full, adding liquid may have caused the vent to let out the excess, and if really full, you may have a leak at the top of the tank where the piping connects, some mfr's use brass nipples to connect the rubber hoses to the tank fittings, these will fail over time when in contact with salt water..

If that's a vacuflush head your problem may be at the filter. Simple fix.

So, the filter if installed would cause the anti freeze to come out the other side of the boat ??

No, being overfilled would do that. I was referring to the odor. The dampness under the bed may just be condensation. I always recommend raising all cushions when storing a boat.

On the damp/wet starboard bunk in the aft cabin, could be the companionway step drain line. We have an '83, same model. There's a drain line that snakes from the companionway (salon hatch) step outside through a little wooden box near the ceiling inside the aft cabin, then into the closet and down past the bed. If that line is leaking that could be the source of the wet bed. Unless they drastically changed the tank configuration 83 to 84, those aluminum tanks under the aft bunks are fuel tanks, not waste. The waste tanks are forward in the engine bay, plastic, and much smaller.

P.S. Congratulations on the new boat. We got ours for an excellent price too. Needed a ton of cosmetic work but sound engines and systems and mechanicals. You get a lot of boat for the money with those older Carvers. We are shopping for a bigger one already (bought ours in 2011) but it's a great boat to learn on. Big enough to be comfortable and teach you how to handle something bigger, but not so big it's a monster. I love the height at the upper helm too, great visibility. The only thing we really don't like are the aft cabin bunks. I sleep starboard, my wife and the dog on the port side. I know some owners have removed the aft head (which we never use anyway) and reconfigure that aft cabin with one bed, but I just think it's worth all that work for a 30 year old boat. Hope yours goes as well as ours.

No, that's a hatch to the bilge. The only things in there are some plumbing lines and wires, and the forward bilge pump. There's not much else accessible from that floor compartment (at least on my boat) but that's normally the lowest point in the bilge, the lowest point on the keel as the boat is resting in the water, so a lot of water drains to that point. You'll need to get that hatch open one way or another, you have to get to that bilge pump. The forward bilge (where any water from the anchor chain locker drains to) and the engine compartment bilge both drain to that spot, so you need to be able to get to it, check the pump, check how much water you've got in the bilge. I'm very surprised that hatch is frozen closed. Hope it's just stuck ad not rusted closed. There are drain holes from the forward bilge and engine compartment bilge to drain into that space but the engine compartment bilge weep hole frequently gets clogged with junk. In my opinion the weep hole is too small but since it's way under the floor and aft it's almost impossible to drill it bigger. You'll need a flashlight and long skinny bottle brush to clean it out.

The shower sump pump is in the engine compartment, directly below the lower helm steering wheel (if you have a lower helm). On my boat it's very hard to get to because the water heater is also right there.

Can anyone help in what are the two blue bags on each side of the engine room are?? Also I try filling up the water tanks and notice that the water was coming in to the out with an 2 inch gray blue hose that is just hanging without any where to go. Can you please help me with this as I am now worry about how to filled my water tanks. I have a Carver 3207 1983 and thanks to all for your help.

You lost me at blue bags. Do you have at least some pics of them and the water fill situation? A video would be great.

THERE ARE TWO LARGE BLUE BAGS WITH HOSES ATTACH TO THEM AND I AM TOTAL LOST ON WHAT THERE ARE AND WILL GET THE PHOTOS SOON OR VIDEO FOR YOU
MANY THANKS FOR YOUR HELP ALSO THE WATER FILLED LINE GOING INTO THE BOAT IS HANGING AND ONCE I TRY TO FILLED IT UP IT JUST GO INTO THE ENGINE ROOM FILLING UP THE FLOOR WITH WATER. IT LOOKS LIKE IT WAS CUT AND CAN'T FINE OUT WERE IT GOES.

Till I see the pics my guess is that the 2 blue bags are solar showers. they'd be kept in the ER to keep the water warm when there's not enough sun to heat them. I suspect the cut hose is to the transom shower which is probably not working (at least for hot water). You have a shore water inlet on the transom. Where is your water fill. I suspect you're trying to fill your holding tank at the pump out instead of your water tank . From the pics I was able to access it looks like your fuel fill in on your port catwalk and your pump out is on your stbd catwalk. Is that correct? I couldn't find your water fill in pics. Where is that? It's possible that it fills through your shore water inlet, but I DK.

OK I just found this video. Towards the beginning they show the deck fittings, 2 on each side. They should be two fuel inlets, one pump out and one water fill. DK which is which, but would love it to be fuel on one side, water and waste on the other, but you can tell by following their hoses if they aren't labeled. If you're filling water in the right place and the water isn't going in you probably have a blockage, most likely in the vent. If it's coming out the hose into the bilge the broken line should be obvious.

I owned a '90 3207 back in the day. The water tanks were saddled on either side of the ER. They were connected with a 1/2 inch hose at the bottom so they would level.

The 1/2" hose was too small so I had to fill the one side very slowly in order for the tanks to equalize. Perhaps the tank you're filling is venting or the leveling hose connecting the two tanks is leaking, missing or has fallen off.

I tried to find info on this, but couldn't find anything. This arrangement really surprises me as most boats have a single water tank either on the center line or counterweighted by other things on the boat. Did it draw from both tanks equally? I ask because each of those tanks could hang over 250 lbs on the side and could really affect stability.

You’re really making me think back... I do remember there being a water fill on both sides. I could fill one side really quickly and then do the other while the tanks were slowly equalizing. Once the second tank spewed out the vent, I would slow the flow on the fill hose right down. This would top off both tanks as they equalized internally. The Johnson effect, essentially.

I cannot be 100% sure but I’m pretty sure the pump drew from one side only. They would equalize and empty evenly because of the connection hose.

Ok, I found the owner’s guide here: https://www.carveryachts.com/support/owners-guides/
I owned a 1990 but the latest manual for a 3207 is listed in 1989. In section G it lists the 3207 as having dual tanks of 70 gal each. Unfortunately, the manual is very generic and doesn’t illustrate the dual tank set up.

It does however, mention that vessels with dual tanks should be filled slowly in order for the tanks to transfer water from one to the other. Like I said earlier, I had two fill caps; one on each side. Maybe they added one as the result of consumer feedback. I bet one guy from Pulaski knows the truth but he’s probably retired in Florida by now. Boats...am I right?
