Got some mud motor + jon boat questions. Thinking of building one.

I have a 14x36 riveted jon boat. I also have a 6.5hp Predator Honda motor clone from Harbor Freight. I was looking for a project to use my motor and I started wondering if I could use the Predator to power my jon boat. One of the first hits on the Googles was about kits to turn a small motor into a mud motor. Like this.

I'm not 100% familiar with mud motors as we really don't need them around where I normally boat. My slough at the lake doesn't get any more shallow than 2-3ft and that takes running to the end of it. We're at least 9-12 feet unless you are right up on the bank. Right now I just have a trolling motor on the jon boat and that's good enough to get us around the slough/cove (around 300 meters long) to do some fishing. If I had something on the jon boat that would get me across the main body of water (about 1100 meters or ~3/4 of a mile from the mouth of the cove to the other bank according to the googles map) there are some great places to fish I've been told. We are on the north end of the lake about 1.5 miles past where the river widens and dumps in the lake. If you go that 1.5 miles north that's where the lake turns into a river and you are only looking at around 250 meters from bank to bank instead of 1100 meters where our cove is. Up along the river there are plenty of spots where a mud motor would make sense. I've seen those guys in the grassy shallow areas up there fishing I've just never had the equipment navigate through there.

Now I certainly don't need a mud motor it just seemed like the easiest way to build power for my jon boat out of a motor I already owned. I just like building stuff and it looked like a fun project to kill a couple of weekends (would probably weld one up myself and not go with a kit). Would a mud motor be a terrible idea for my use case? Having never used one I have no idea how they operate/handle compared to a traditional outboard.
