Measure how much wider to the tunnels you can go and we can see what replacement tabs you could use. As I mentioned I cannot really help with larger Tabs fore to aft. Also you will need to reposition the actuators so that they are in the middle of the tabs side to side.

Yes, we have made different stroke actuators for SeaRay. Often when one needs to be replaced it is replaced with a "standard" actuator resulting in what you are experiencing.
Is there any way you can post photos of both sides in the full up and full down positions?

I have seen extensions work fine, some examples here on Club SeaRay. But since I work for Bennett and we don't make or test them I cannot recommend them or give guidance about them.
Drop Fins do help and adding larger Tabs do too.
Do you have a photo of the transom and Tabs you could post...
You can a little bit, but you will reach the point of diminishing returns very quickly! Not sure what you mean by "some detail from the forum vendor would be great".

Yes, the hinge on the transom! On most of our Tabs it's an interlocking hinge. It's very strong and corrosion resistant, but unlike a piano hinge it cannot go all the way down or up.

Two things to be concerned with.
You may indeed be pushing the interlocking hinge too far down and damage it or bend the Tab itself.
The standard angle of deflection for the Tabs provides the best lift to drag ratio. If you deflect it more than that it will create more drag than the addition...
Most likely a 12v on that boat. Here is a link to the sensor installation instructions https://bennetttrimtabs.com/installManuals/AutoTrim-Pro-Sensor-Installation-WEB.pdf

In order for Trim Tab indicators to work on a NMEA system sensors must be installed in the actuators (rams). The first thing to do is determine in the sensors were ever installed. https://bennetttrimtabs.com/product/nmea-2000-indicator-kit/

You really don't have room for wider Tabs to make it worthwhile as the actuator needs to be centered in the Tab side to side.
If you feel the boat needs more lift. You can add DF12 drop fins to the existing Tabs. They capture water pressure normally lost out the sides of the Tabs and channel it...
If one side is not working, take a look at this video:
Then do step 3 below and let me know what you find.
