Well let me put it this way, in the marsh it has by orders of magnitude better control than an outboard engine. Now that being said I can navigate in places that normally the outboard would clog the prop in maybe 5 feet of forward motion, the longtail still clogs but I will have moved forward 35 feet or so in this heavy stuff. In the Lily pads there is no stopping it just motors thru.
In shallow water on the rivers it just keeps digging the sand and gravel in those places that the boat just floats and very little if any damage to the prop from hitting stuff, it just jumps up. Long tails can be hard to manage at times, much more so than outboards in those places where you hit a lot of sub surface objects. Since I'm shy on power, for high speed travel and clear mud, it maybe won't go where the real mud motors are used but we don't have those conditions around here.
I hope that answers your questions, if not give me some specific questions and if I have any experience in that regard I will try to answer your questions. Lost
