What model boat and what model motors?
It is difficult to see the cracks in some of your photos but based on what I can see, he transom is flexing. The second pic is the more worrisome since behind that area on the port side is where a stringer bonds to the transom. Although I dislike the climb on the motor lower unit and bounce up and down, in this case that stressing may help you determine how much flex the transom is experiencing. If you visible see the crack opening or closing as you stress the rear, that is not a good sign. Are there any stress cracks on the outside of the transom?
You probably would benefit by having a fiberglass person take a look, tap around a bit and look for any evidence of a soft/wet transom core.

Look at the rub rail to see if there is any cracking. If the transom is moving or swelling you will get cracks under there too. Does the aluminum bang cap look swollen?

This looks like a Grady 272? Can you check the stringers in the transom where they connect? That would be a good indicator as well.

Thanks for your advice
It’s a 2002 sailfish 282
with twin 225 Yamahas
I have it stored on dry racks
I will this weekend have a closer look
The rub rails are good
Is the transom ply wood or synthetic?
Thanks

It has greenwood xl as a core.
I'd rock the motors a tad and see if you see any flexing. Maybe have an experienced glass guy look at it.
You may be able to do a quick repair and watch it closely.
Likely heading towards a transom rebuild at some point. The wood likely will be solid but wet and delamination is a likely concern. Hoping for the best for ya.

This is what you may find. In which case a transom rebuild is most likely on the agenda at some point.

Agree with Fishtails, probably delaminating.

Thank you
I’m going over this weekend to access the issue and hopefully find a solution
in meantime I’m going to cover the cracks with gelcoat
Once again thanks to everyone who have given me advice

Gelcoat is very brittle. It will recrack in no time if there is any movement. For now just to keep water out, apply a sealant/caulk like Life Seal

I went to my local marine shop , they suggested a spray on elastic rubber
It’s flexible, robust weather tight
I got a can of raptor protective coating
I can only try , there other products available but it’s a band aid solution at the moment
Thank you for your advice

New Great Grady Sponsor opportunity?

Maybe add it to the Grady transom sticky under maintenance?
Sorry, I'm being a little cynical today. This issue reminds me of a movie:
