1990 220 da toilet

[Ben Maggio]

I have a dometic rv toilet that had a rear discharge pipe that goes to a marine pump out fitting on the side of the boat but it's a manual pump toilet. Does anyone know if there's an electric flush self contained toilet that can be piped from the rear to be used and emptied via a pump station as opposed to taking it off the boat.
Thanks

Went from a 380 Sundancer to a 220 da that's much older and I'm looking for an easier toilet to use instead of the RV porta potty
