rob8888 is on a distinguished road
In many marine toilets the toilet needs to be mounted at a height so that the water level outside the boat is about 1/4 way up the bowl to get the bowl to fill to the same level. Put a temporary clear hose on the flush water through-hull and mark the water level on the wall beside the toilet with a piece of tape or a pencil, then install the toilet at a height that will put the line 1/4 way up the bowl. If the toilet is higher than the water level it will pump OK but it won't partially fill. The water line between the hand pump and the back of the toilet where the water goes into the bowl needs to be run several feet above the water line and have an anti-siphon valve at the top of the loop to make sure the toilet won't start a siphon and sink the boat.
