I agree, a mud motor is kinda of pointless down here. Ive seen guys use em on the coast but they never got anywhere that I wanted to go and couldnt. Sure they help when your stuck at low tide and your boat is beached but outboards seem to be the way to go. Especeially with an 18 ft boat, I dont know how much having a mud motor would help. But, like woodie wacker said, could be a great diver/river set up.
