Recently my water pump started leaking so I’m looking for an all metal replacement so I don’t have to worry for a long time. It came to my mind to use an electric water pump like they use for the more modern engines instead of belt driven one in theory this should free up some hp from parasitic drag. Is this a dumb idea cause I haven’t seen anyone try anything like this.
