I'm interested in this point because I had a 135 merc that was a bitch for this problem but I never checked the offset

Thanks for all the advice and it has confirmed my intended solution to install a NFB steering system and any advice regarding the use of a 3 turn or the 4.2 turn option is welcomed

4.2 will be easier to turn but take longer to steer.

If you're going to install a new steering system then the 4.2 turn one is a better bet in my opinion as Cookeee has suggested.

However you still haven't mentioned whether you had this same problem with different trim positions?

The steering does get a little lighter the higher the trim angle but you would have to be right at the top of the trim height.

Have you got the engine height set correctly? The AV plate should be about 1" above the water when planing. If you are set too low, more of the gearbox is in the water increasing the drag.

Hight and mounting position all look good!

For standard engine installation on RIBs particulary with higher powered outboards is to offset the engine by between 1inch-2 inches to the right (starboard side). This will help the torque problem. The variance depends on the engine size, but in your case check the position of the engine. If it has been installed bang in the middle of the transom I would then recommend you move it 1 1/2 inches to the right.
