Center the tab, run it and adjust as necessary.
I know, but there is a side it needs to be biased towards just based on prop rotation - figured that someone would know.

Based on Newtons third law of motion, if you have a clockwise spinning prop, the "P-Factor" is to the left. However there are many variables/imperfections in individual hull and sterndrive setup and/or transducers, pitots etc... that may mitigate or exacerbate this.
So what does this say in a nutshell???
Exactly what Don stated...Put it straight, run it, adjust one "notch" at a time in the direction of your yaw, until the tendency of uncommanded turns one way or the other is gone.
And the smaller offset trim tab may not perform(based on reduced rudder area)as the larger one.
If just countering for torque and nothing else...then you would put it tail to port if looking at it from the stern.

As would his primary rival... Sergei Korolev.
Do you have power steering?
