The trim anode is supposed to be used to offset the natural "turn" generated by the prop, so it's not cheating as such. A right hand (standard) prop will try to push the skeg to port, so set the anode slightly to port to bring the skeg back to centre. It can take a bit of playing, but mine is set 2 notches to port (the notches are at the rear of the anode) to centre my RH prop.
But I think lifting the engine may also help if this doesn't do anything. The anode is an easier "fix" if it works! Good luck.
