If this is a NEW build, Mono hulls most ALWAYS lean a bit from prop torque. We counter this with a little bit of INSIDE right side trim tab deflection.
A PICTURE of boats transom viewed from prop end will tell us a lot

What prop are you running? we had trouble with abc props with a lot of blade area.

I had the same problem with the apache.
Don't start it, put it in very calm water and see if it floats level.Some are not made very well and won't float level.Once it floats level, or even a little to the left check to make sure rudder blade is not bent and that the turn fins aren't in the water when going straight.
Sometimes a strut that has too much prop in the water will cause it to torque roll, you should have a surface drive on the boat and have the shaft center line no lower than 1/2" from keel.
Put a prather 275 prop on it and see if it goes straight.

Out of 3 hulls we had one would never right.
If it still doesn't run right, put it on ebay.
