Leaning Left

Dear Bob:

Q. I have a brand new 28-foot catamaran
with a single Mercury Racing 600SCI, Mercury ITS, and a Mercury XR Sportmaster drive running a 28 pitch 4 blade Mercury propeller. This is my first Catamaran. With just a driver and passenger the boat has a noticeable lean to port when on plane at any speed. I realize this is caused by propeller torque. At the direction of the boat manufacturer, I burn the fuel out of the left tank first to help the boat ride more level. My question is: What else as a driver can I do to alleviate this lean? Would a set of trim tabs help or just create another problem? Any advice you can give would be greatly appreciated.
