Twin Merc 888's,Boat lists to one side when running on plane

[holorinhal]

I have a 25' wellcraft Nova with twin mercruiser 888's. when the boat gets up on plane and starts running, it lists to one side pretty bad.
both engines are running at same rpm, and weight distribution is pretty even.
Could it possibly have something to do with the trim?
I would like to here some thoughts on this. Thank's.

If you don`t have trim tabs , NO.
Both drives should be trimmed the same but if the drives rotate in the same direction (not counter rotating) you will heel to port due to prop torque

The boat does not have trim tabs and it is the port side that it lists to,but it seems to be drastic.
I am prety sure that the engines rotate the same direction.
Would a set of trim tabs help this situation and how do the trim tabs work if You have two drives with trim?

you would lower just the port side to lift the stern
trim Tabs are best suited to leveling a boat or load more than a trimming action.

Should the trim tabs be fixed(manually adjusted) or electric /hydraulic controled?
