How can I connect or link boat motors? - new boat motors

I have a 18 feet by electric motor. There are three engine mounts. When configured for higher speeds (25 mph), with two motors evenly over the bar spacing. To drag at low speed, I use an electric motor centered on the table. Is there a connection available, which allows me to easily switch between these configurations?
