I got a Momarsh fatboy dp with 7hp Stumpjumper on it, I love this rig.
I got burlap with killerweed woven in to cover the motor and dog.
That bever attack boat looks a little too small for me. That Momarsh is an awesome layout blind, lots of room, and the way got the the motor installed it works great. That bever attack boat, I would use something like that to pull around, I would not mess with a motor on that. Jmo.
