Any issues or pointers that might be helpful when I remove my tank? I have a 2000 Carver 356 Aft Cabin purchased this summer. I think the lower fitting may have frozen at some point. What tank/ manufacturer did you end up using? Thanks for your response!
I did not end up replacing the aft tank. Shortly after I finished the forward tank I ended up selling the boat. I had most of the supplies to do the aft tank and sold them with the boat.
Some pointers: I wonder how large your tank is and if this might be an opportunity to make it larger. I had a friend with a 356 and he constantly complained about how small the waste tank was, but that might be because he also had kids that would take every opportunity to fill it up. I had a total of 80 gallons and he had 28, so I thought he had a legitimate concern. I got my tanks from greatlakesskipper. They were not exact replacements but a better size for my application and were MUCH cheaper than anywhere else I could find for a quality tank. Mine were stock overruns for a Larson boat.
Heat is your friend when working with the hoses. Even just sticking an old-school incandescent trouble light down by the hoses for a while will soften them up and allow you to flex them easier. Applying too much heat too quickly will be a problem because you need the heat to get all the way through the hose to really be effective and you don't want the outside to get TOO hot.
While you're in there, consider replacing the tank monitor system with an "outside the tank" system or one that uses probes embedded in the tank. The float-style monitoring constantly gets complaints about floats getting stuck with debris.
