Aircraft
On night of (date) we were assigned to Aircraft X which was equipped with a permanent EFB (Electronic Flight Bag) mount located in the center of the clipboard on the side; number 2 window. I attached the EFB in the vertical position to maximize chart size displayed on the EFB. This resulted in the EFB being located in a more forward and lower position from my usual mounting location; on the lower rear portion of the side window. As we began our taxi out I noticed my left forearm was directly under and pressed against the lower edge of the EFB. Turning to the left was slightly awkward but manageable as I had to push the nose wheel down. The major hindrance occurred during right turns. This requires a lifting and pushing motion on the nose steering wheel. In the only position available; the left forearm is pressed upward into the bottom of the EFB. Any lifting motion is impeded by the bottom edge of the EFB. Only after repositioning the left arm in a much less natural position and to the right of the normal position; is there adequate room to fully manipulate the nose steering wheel. This issue reoccurred during landing rollout. Soon after landing; when reaching speeds where rudder pedal effectiveness is reduced; the Captain will remove his left hand from yoke and place it on the nose wheel.This typically happens when decelerating through 50 to 60 knots. The left forearm is in its natural potion; directly below the EFB. Any right hand turns requiring a lifting motion will be hindered by the EFB. The chances of understeer; caused by the pilot's inability to turn right; without hindrance; is great; especially during a high speed right hand turnoff. This is exactly what happened during our rollout and right hand turn. My ability to move the nose steering wheel was much hindered and only after repositioning was I able to turn the wheel to the right. This design was not thoroughly vetted and needs to be removed.
B737 Captain reported the location of the EFB with mount in center of clipboard inhibits movement of tiller; especially during right turns.
