Like BCB said, trim up. It sounds like youre running with the motor fully tucked down. All boats will do this. As you trim up, the propeller becomes more in line with the flow of water, and the left side will come up, as will the bow. Speed and straight line handling improve too.In reality, the left side isnt dropping, its that the propeller is at a severe angle to the flow of water, and the leading edge (which is the very bottom in a tucked motor and rotates clockwise looking from behind) is paddling the underside of the motor hard right as its thrusting forward. When trimmed, the leading edge slowly becomes the whole propeller, and possibly the top of it in a highly trimmed situation eliciting the opposite reaction, hence the tendency to chine walk.This is a common phenomenon in airplanes too, except they have to deal with it in 3D space.
