Aligning sailboat propshaft w cv joint between motor and proshaft?

[GreenHeaven]

I have a mysterious flexible coupling from the mid 90s, probably French since its in a Jeanneau, between engine and propshaft. It has two "CV" joints, one at each end of a short stubshaft. see pic

This will permit engine misalignment due to vibration etc, but how to set it up optimally? I presume minimizing the angles would be the guiding principal.

No pic.

Set up as straight as possible to reduce failures.

It sounds like you have an “Aquadrive” shaft, or one of the several competing brands.

An internet search for Aquadrive installation manual will tell you all you need to know....
