I've had an Outcast Fishcat 9' for over 10 years now. I like it. It is equipped with a motor mount. I tried it at Maligne Lake a few times. By the time you add the weight of the electric (not sure about the thrust) and the battery, it was weighed down pretty goon. Shortly after, I had a few pin holes in my bladder, which the Fishin' Hole in Edmonton kindly replaced. But, I figured the bladder leaks were the result of all the extra weight from those trips. Can't be sure but that's my rationale. So, although that pontoon is equipped with a motor mount, I won't put an electric on there again. Although, I think not all electrics weigh the same, right? Other than that, love the boat. Good for lakes. Floated the Bow and Red Deer rivers with it too.
Good luck.
