I Need to choose pushrod extension for Raymarine Tiller Pilot ST1000.
The distance from the mounting socket on the starboard to the center line (“C") is 705 mm about 27.8 in.
Which extension should I buy?
The D006 (for 27.2 in) or the D007 (for 28.2 in)
When motoring the propeller walks the the stern to port so the tiller has to be pulled to starboard to correct the course which make me think that the shorter extension may be better.

Welcome to the Raymarine Forum Paul,

Given that the performance of your vessel under power requires that the rudder position be to the port side of center, your thoughts concerning use of a shorter tiller arm extension may have merit. However, be aware that when under sail, the vessel will turn more slowly to starboard, as the shortened tiller arm extension will result in correspondingly less starboard rudder range.
