So I found a motor! Slow RPM with high torque and 115 V. It is "wheather" resistant to reduce corrosion.
The valve is 1 1/2 inlet/outlets, the flow pattern is unidirectional with one output flowing at a time. The motor will need an adapter to mount to the shaft of the valve.
So the total so far is;
$48 for the 5 way valve
$59 for the HD 115 V 15 watt motor
total=
$100 for a DIY with no warranty.
