OK......my "baby" boat, a 1990 Quantum 1600XB (by Bayliner) bass boat has a slight imbalance problem that I think can be solved by trim tabs. With full load, two people, one starting battery and two trolling motor batts, it leans to port.

But, after looking at Smart Tabs, I'm not sure if or how I'd get them to mount on my transom area.

Below are some pics of the rear end of the boat. It measures 59" wide from outer edge to outer edge, 29.5" from midpoint to outer edge. But the problem is the slant on the rear, as you can see in the pics.

Now, according to Nauticus, you mount the tabs 3"-5" in from the outer edge of the transom and at a slant to match the boat's bottom. But I don't think I have enough flat space to mount them.....does anyone know how wide the mounts are for SX9510-40 or the ST980-30 tabs? Honestly, I don't think I've got enough flat area to mount them, unless someone's got an idea.

Forgot to add......one of the problems fitting them is my transom tie down straps and the possible interference they may cause. Pic below of it in place......

I just installed Bennett trim tabs on my boat and i don't believe you would be able to mount them due the shape of your transom?

The plate sizes are, 9510=9.5x10 980=9x8, hinge is no more than the width of the plate, actually the hinge is a little smaller than the plate. I think you can mount them on your transom, straps may get in the way, then may not, tabs may hang low enough that straps will clear, plates will hang down at an angle.

Here is what I had to overcome, yours will have to mount more inboard than mine due to your hull design, they will still work fine.
