In my experience, the prop offset was designed to offset the effect of “prop-walk” when motoring forward. The trade-off is that the boat will “prop-walk” much more in reverse with the offset. If you have ever tried to drive a fin-keeled boat that has no offset in the prop, you will very much appreciate the trade-off. Every fin-keeled boat with no offset that I have ever helmed pulled to one side with a surprising amount of force when motoring in a straight line, and that gets old quickly! On our boats, that means a slight offset to the port side for the prop but the amount needed changes with every prop and rpm setting. the bonus is that we can remove our prop shaft without dropping the rudder. The negative is that the boat will pull to port dramatically when you go to reverse and use a lot rpms. James Delaney C&C Mk 11 Oriental, NC

This allows you to remove the shaft without removing the rudder. It also means the boat pushes to port while going ahead and pulls to port while going astern.

The shaft has to remain straight to the transmission.
