What's causing the boat to list?

Don, Thanks for getting back to me. I checked the hull with a four foot level, and nothing unusual. The boat is sitting on a bunk trailer. I measured the motor mount, 33 inches from port to motor mount and 32 inches from starboard side to motor mount. Could that one inch offset cause that much of a problem?

Also, the boat settles down with a full load of gas, only as it empties does the problem get worse. The tabs don't completely push it over, and if I trim it too hard with the tabs it just dumps the bow down and still dives to port. Craziest thing I've ever seen. Regardless of the trim positioning of the motor, the problem is persistent. It is mounted on the highest hole on the motor mount, no pin on my Merc. And its a 175 so no problem with power, it will top out near 50 mph. Any other ideas? Also it has a four blade prop. and a big T-top on it, but I don't think that would cause the problem.
