hey.. its the buzzbait guy i just replied to! ha ha. I just joined the site, and am searching Illinois stuff. I basically only use a kayak now. I have a 16' bass boat and a 14' jon boat, and I MUCH prefer a kayak. A big reason (and probably a reason for most people) I got into it because of gas prices, always charging batteries, hauling a boat around, just the typical hassles of a boat. But now I prefer a kayak for the many advantages it offers for fishing. Mainly, it is super stealthy. I've caught bass on beds in my yak 3' away in 2' water. I didn't mean to get that close, but when I saw I had drifted up on it and it was facing away I dangled a senko in front of its face. That is when yak fishing took over. It gets in your blood...bad. I have no desire to use my bass boat anymore, but a lot of that has to do with a comfortable yak. I have the 2013 Wilderness Systems Ride 115. It has a comfortable seat, and you can stand in it. Being able to stand and stretch your legs will make yak fishing a million times better.
We share Emiquon as a favorite lake, so I'll use it as an example. I fish this lake now more than any since I can see it out my living room window and it produces soooo many fish. A kayak is the perfect choice for this lake. You wouldn't think so because it is so big, but it is not as bad as it seems. If you are only using one trolling motor and one battery (Since it is a trolling motor only lake) you are limited on how far you can go anyways. More often than not, I can go faster with a normal rate of paddling than most people can trolling. I've even towed people who ran out of power.
Another reason a yak excels at Emiquon is the weeds. At a certain part of of the year many people will just stop fishing here. Trolling motor+weeds does not make for a fun day. With a yak, you can paddle right through or on top of it. It takes some muscle sometimes, but it's a lot better than pulling weeds all day. Plus when it gets really windy, you can pop up on some mats and stay in place. This is hollow frog paradise. My favorite thing in the world. There are many days in the summer where I can do this and catch 50 bass in 4 or less hours. I kid you not, last season I caught 9 bass in 9 casts, with the smallest being 16.5". The best part... jon boats cant get in this slop. The worst part is paddling back when you're bleeding from bass thumb, but it is worth it.
Once I started using a yak at Emiquon, I started catching way more. I believe the biggest reason is stealth. The lake is shallow and they aren't used to loud noises (outboards) This causes them be pretty spooky. It gets breezy there pretty easily, and the splash off of an aluminium boat scares them as well. One time, I was nailing them bumping squarebills off of old concrete. A guy in a jon boat came close to see how I was catching them, and as soon as he did the bite turned off like a switch.
Before you buy, do TONS of research. It is hard in central Illinois, because quality fishing yaks are not really available. If you want, we could meet some time and I'll let you try out some yaks. Along with the ride 115 I have a Wilderness Tarpon 100 and a Perception Sport Pescador 12, which is the 2008 model of the wilderness tarpon 120. I know someone who would also probably let you try some different ones as well. It would be really helpful in your decision making, especially if your gonna spend 1500-2000. Keep in mind you'll have to buy a paddle and a high back pfd. Account for $400-450 If you want nice stuff.
Some trolling motors made for yaks:

If you want to mount your own, I would think the wilderness commander would be good. It is a hybrid (canoe/kayak)
Yes, you can install a fish finder. There are many ways to rig them now.

Sorry for the long post, but I really would like to see more kayak fishers in central Illinois. Maybe get a group going. Let me know if you have any questions. I live for kayak bass fishing.
