Looks spot on!

One could, weigh everything , includig the hull all up and take a look at how the weights sit in the hull. placing them to get the boat flat on water and then move parts and pieces fwd and aft to see where it likes to sit under way. With your rig , trail and error is the watch word today.Comment

I am thinking to cut and modify the deck because of 2 reasons:
1. center of gravity issue
2. I would like to have a center console rib design
I am going to leave a bit of the vertical part ( follow the marker lines ) just for stability of the hull.
Any thoughts / suggestions ?Comment

You are going to have to figure out a way to get the batteries farther up towards the bow in order to balance it properly. Might end up altering the current layout of the deck. I don't think you have any choice.Comment

Since there are no more suggestions apart Pantchothedog’s -thank you my friend- I have made some mods to the hull the last days.
Servos are mounted in a temporary plexi. All movements seems to work fine.Comment

There is enough space around 18cm to move batteries to the front 1st picture and close to the middle of the boat 2nd pictureComment

So now that CG considered like no issue any more I would like to ask about the proper height of the outboards.
is there any golden rule ?Comment

For Tunnel hulls powered by outboards looking for top speed the center of the prop is usually even with the bottom of the sponsen. I think you will want your props a little deeper. Maybe the top even with the deepest part of the hull for starters. Might end up taking some experimenting, especially since you are interested in scale appearance more than speed.Comment

Thank you for the input. I think that Tunnel hulls require different setup than the deep V hulls.
In any case the travel of the jack plate is approximately 25mm so I believe that somehow we will find the right height.Comment

With 25mm (about 1 full inch) of up and down travel, I feel you have enough movement to find the " good " place. You might even be able to start deep, and once on plane trim them them up a little just like a full sized outboard powered boat would do.Comment

I love a scale build.Comment
