Mounting with CMC Tilt & Trim unit

Managed to get my hands on a CMC after market T&T unit. Want to mount it on the SR4 with a 30hp outboard.

Has anyone any ideas or suggestions on heights to mount it? The general opinion is that it is mounted so the outboard fin is 2-3" higher that the bottom of the transom? Anyone ever fitted or used one?

PT-130 Power Tilt & Trim (Item #13002), $0.00 : Cook Manufacturing Corp.

With the setback, you can run the motor higher than if it was on the transom, but I have no idea how much. 3" sounds like a lot to me, but you're in semi-charted territory here. Any way of doing a temporary mount to gauge performance?

There may be a few holes I can play with up and down.
