I don’t know about toilets but the Raritan Marine Elegance will pump that far easily. I have installed them in previous boats and have one in my boat waiting to haul my boat for winter and I will install it then. You really want the discharge hose to slope down to the holding tank so the sewage will gravity drain and not sit in the hose. Otherwise you will have to do extra flushing to pump the sewage into the tank and have clean water sitting in the hose. When you put the new holding tank in it is best to put a vent to each side of the boat and make them at least 1” diameter, that will promote air getting into the tank and will help aerobic bacteria growing. It is the anaerobic bacteria that causes smells.
