I think I understand his problem. After emptying the bowl with the 'dry' flush, water slowly leaks back in mostly likely from the exit hose thru leaking seals. My boat does something similar, although it only comes up about 1" above where the exit hole widens. If the hose or tank were positioned at a different level, I suppose it could fill the bowl higher in another boat.
I suspect a rebuild kit would fix the problem, but I haven't taken the time to fully investigate.
