Jason, are you trailering the boat?

If you have access to the bracket interior, place some towels on the bottom of the bracket, and tape wads of newspaper over the likely leak areas, then take it for a brief spin. The newspaper should give you an indication of where the leak(s) is/are. The towels will help prevent the leaks from showing up places where they aren't (if that makes any sense.) Only works if you can get to it though.

For those asking, on the 7m Zodiac/Wiliards they use a big hull extension/engine bracket. It's fully buoyant to offset the weight of the outboard.

Yes, I'm trailering it. Have access just don't want to start pulling hatches Have no choice though.

Water will find its way, always tricky to locate ... Is the bracket welded? Any chance that under way, due to dynamic forces, a seam i leaking but on trailer, stationary, its keeping tight?

Another thing came to my mind. What i You fill the space with water when on trailer, then should be easy to sea the leak place? If no leak can be found, its possible the hatches that are leaking? Good luck!

Need to be a bit careful doing this. It is possible to fill it with enough water to overload the trailer (that's also true of filling even small inflatables to find leaks.) Granted the bracket shouldn't be a huge volume of water (a lot less than, say, filling the hull), but it will all be at the back of the rig.

Yeah, I thought about both options and had the same concern. The bracket is big and the water weight would be a concern.

As for a crack the bracket is newly painted so if there was a crack that big I would expect to be able to see it in the paint. I've inspected it when it's floating too but obviously not underway.

I think I'll got with a plexiglass hatch cover. I think i can do that. Then I'll be able to see. Maybe stick my gopro back there to look in.

Putting a jack and some wood to distribute the load beneath the bracket should take the additional load of the the water(subject to securing the trailer in place first).

Long time a go i had a boat with a similar issue, that time my solution was to fill the void by high quality 2k PU foam. Modern Epoxy foam will not suck any water, still think its better to find the leak as first priority.

RIBase
And place a big balloon (or anything else with less weight and big volume) in the bracket before filling it up with water.
Than you need less water to fill the bracket, thus also less weight..
