I think my only concern would be is whether or not the pad can form or mold to the contours of your boat. I am not familar with the 681, so if it has a nice and truly flat area you can mount it, you might be alright. If it cannot form to your transom (given your transom is not completely flat where you are mounting it), I'd be a touch hesitant to go that route.
If you have the ability to mount your transducer inside your hull, that is really a great option.... That all depends on the transducer type, though as well. If it has downscan or sidescan capabilities, then in-hull is not a good option.
I ran into this dilemma with my boat. Didn't want the transducer off the back as it already had multiple holes in the transom from the previous owner, so I epoxied a basic transducer in the hull, then mounted the side/downscan transducer under the setback on the boat, so it is protected by the motor as well as the boat itself, as it is not at the bottom of the boat. I did this because the side/down scan doesn't work at speed so it was a non-issue to have it out of the water as I am running down the lake. This was with humminbird electronics so all I needed was a y-cable for dual transducers. I'm not sure all products out there have that option, though..
