Is it just you in the boat? If so, even though it is a larger boat, it will have a tendency to tilt right and turn right. If you have equal weight on the port side it will still want to turn right due to torque steer via prop tilt, but it shouldn't be excessive. Usually the boat would have been tuned to minimize this. Are the center fins all straight or set up correctly? How about the engine position and cutlass shaft alignment? With the duaI rudder it is a little more difficult to field tune, but play with the toe-in between the 2. You may need to grind the rudder(s) to act as a trim tab for the turn. However, this would be a perfect use of your extra trim tabs.
My only issue is trying to get the nose to go to the right when backing (tilt steer and rudders). All of the locations I dock to in bad weather are a PITA to position without risking a hard rub!
