As mentioned I really like my boat but there are things that I would like better. Rod storage is a problem but I think I can with a little work fix that. I understand where another poster mentions min of 90 HP. My 50 HP moves my boat at about 34 MPH which is as slow as I want to go but in reality it's faster than many boats I see locally and so I get there a minute longer than the next guy, so what.
I have about 5K in my boat/motor/trailer so when the times comes to upgrade I will have definate opinions on what I want. Since I'm 1.5 hours from the Jersey Shore my next boat will most likely not be a bass boat, rather it will be something for big water and will keep my present boat company for fresh water lakes. For two people it's fine, three can fish but it's crowded. I have two sonars and a live well and bow mounted TM. I can fish local tournaments with it no problem.
My motor is a 2005 Mercury 50 HP two stroke. It probably sat for a year before I got it. I mention this because it took me about 4 boating months to get all of the kinks worked out of it. It was worth it though because now it's really running great and I have a fairly good grasp on how this thing works. Although we had several boats when I was a kid it's been many years since I've had a powerboat and the need to trailer a boat. A 16 foot aluminum seems to be a good place to start, easy to tow, easy to operate, and a good learning (or re-learning) platform.
I have over the years tried to convince myself that I got having a boat out of my system when I was a kid. My wife actually got this whole thing started. Believe it or not she mentioned several times over the course of about 6 months that having a boat might be fun. I tried ignoring her but over time she wore me out and so here we are!
I have a friend that has a 17' fiberglass with an I/O drive. It's not an intended bass boat but he has modified it to work as such. There is a definate difference between the ride quality between our boats, his is quieter and smoother on the water. But his also cost much more to buy, maintain and the run. Bigger motors have bigger gas tanks for a reason.
I know guys that have 12' jon boats and they both love them and can out fish me any day of the year. Simple is sometimes better. Whatever you do get something you can afford, something that is seaworthy and mechanically sound. If that is a jon boat then good, if that happens to be a 21' bass boat with a 250 on the transom then better. You don't want to be a slave to your boat but you also don't want something that leaves you 3 miles from the ramp due to a breakdown.
