Wow thanks for the advice. As I only hav ethe boat new recently i'm not looking to go crazy into modding it yet, all I want to get is the height right

At the moment she is sitting 40mm off the transom. This 40mm is from the top of the transom, to the bottom of the engine support, where the engine would normally rest on the transom, get me? In other words, between the boat and the engine, there's a 40mm block of timber there.

I tried lowering it 25mm, meaning it would be 15mm off the transom but didnt think to bring the GPS

I suppose only time will tell, ill bring the GPS with me next time i'm going out and see how she acts

Is that simply a wood block that you are using as a spacer between the top of the transom and the OB bracket? Is that a temporary thing til you get your OB height dialed in? I've seen pictures of alot of Tcat rigs that do not use a spacer, but it seems to me that not having a spacer would create stress concentrators on the transom right around the bolt holes as well as alot of shear foces on the mounting bolts themselves.

Once you dial in your exact OB height, will you use an aluminum or ss block as a spacer? I suppose a waterproofed piece of hardwood should do just fine as well.

IT is a 40mm block of wood that came from where I bought it. It takes a lot of the pressure of the engine, taking a lot of stress off the bolts

If I lower it 1 notch, it lowers it 25mm which is way too much - Ideally I need to cut out the holes so it's one big slide and lower about 10mm so it's 30mm off the transom, then get a bit of hardwood or similar and wedge it in
