I will be using an Aquadrive cv joint/thrust bearing so there will be no

Go with the cone then, a multi-plate clutch is mostly for buffering the
thrust loads under partial engagement.

The thrust bearing is a great idea, I wish our boat had one. Makes the
power plant a lot quiter and most of the attached ancillary equipment is
longer lived.
