Dan, from what I understand and from what you say, my guess is that there may be different ways to close the coil 12 v circuit on outboard solenoids. Some may ground thru the bracket… the ones with one terminal. These I suspect would be mounted in a metal junction box as a common component ground. If an outboard application called for the solenoid to be otherwise mounted, then the two terminal type would be employed. In any case the significant difference between the outboard type and the automotive is that there is no internal connection to the full 12 v output from the large starter cable lug. The purpose for that connection in an automotive application is to connect a full 12 v to the ignition coil during cranking, bypassing the coil voltage drop resistor.
