Why does my V drive only turn to the right in reverse?

Question

2007 Moomba Outback V

Answer 1

shift cable needs adjustment

Answer 2

Characteristic of having a V-drive boat. Every one I've ever driven does that. I don't know the actual physics behind it (didn't care). Just don't launch the boat with a dock near the right side of it.

Answer 3

This is caused by the wheel effect from the prop.

The water on the bottom of the prop is harder to be moved than the water on the top right below the hull making the prop want to wheel on the deeper water and so making the boat to turn to the rotating direction of the prop.
