Guys, thanks for the replies. The 'fin' I was talking about is just below what I think is the 'cavitation' plates on the motor. You loosen the nut and you can turn the 'fin'. If all else fails, I'll set it back to 'Center' and deal with the 'pull' getting up to plane until I can get the motor trimmed up and the steering goes 'neutral'. This is usually only 3-5 seconds. Just CANNOT let go of the steering wheel during this time.
