Just bought this awesome machine! The middle ballast, aka, the one in center of boat, fills up nicely. But won't empty. I ran it for an hour both sitting still and moving at varying speeds and only 10% of the bag eliminated. So some water came out, but not much. Any ideas?

And where does one but the triangular brackets that attach to the bars that hold open the back three panels for engine and storage. Mine have rusted.

Thanks, glad to be on the Forum. Maybe I can return a favor someday!
