Does anyone know where the waste tank is located on a 2004 280SC; I can not find it? Trying to figure out why my waste tank guage is reading full after I've had it pumped out several times now. I think it may be the float, for the guage, that's gone bad.

Come on guys, I can't believe no one knew where it was. Anyways, I found it. For all you 280SC/320SC owners, it's under the seat just behind the drivers seat. Take the cusion off, take out all your junk you have stowed away and it's under the carpet (that's why I originally could not find it) inside a storage compartment. Inside that storage compartment is the hot water heater (if you have one). Obviously, I did not realize I had a hot water heater as I never used it. lol Keep in mind, we just bought the boat back in June. My waste tank is def. empty so the float must be the issue, which I can easily get to now that I know where to find it.

Toilet paper can hang up the floats. I would bypass the water heater if you never plan to use it. Will make winterizing much easier.

I was like a kid on Christmas when I saw the water heater. lol We will use it, now that I know we have it, for taking showers on those overnight stays. No more cold showers. There was no toilet paper stuck to the float so the float/sender must be bad.
