I posted this to a number of groups as I'm sure it's of interest to all.

I'm looking to purchase a CV coupling to go between the engine and the prop
shaft.

The two contenders seem to be either an Aquadrive or a PythonDrive. The
PythonDrive is cheaper. Has anyone any experience with the PythonDrive.

Will it handle movement from a soft mounted engine in up/ down, side/ side
and fore/ aft directions.

My engine is currently coupled to the prop shaft with a R&D flexible shaft
coupling, this is basically a plastic plate that can flex slightly. Although
the setup works, it's a bit primitive. At certain throttle settings the
engine bounces about a bit and vibrations can be felt.

Any info will be appreciated.
