And it's the engine torque (usually Starboard, counter clockwise when viewed from above) that the little fin is on the motor to counteract, that's why it's turned to the Starboard to push the motor back towards the Port.
It's quite the balancing act when you nut it all out eh jimmbo?
I like to start with arranging weight to get the boat level & fast plane with a shallow 3 to 5 degree attitude as they say that is the best.
Then move on to the engine torque by adjusting the little motor trim tab and finally use the T&T to even out any steering torque. I don't try or need to change the boat attitude much with the trim at all.
All in all it's like herding cats when you put engine height & various props into the mix.
