I have a 2007 PT170 w/ a 4 stroke 25hp on it. Works great for me. I can go any where with it except Lake Erie on very rough days. And I also can get WAYYY back in some places bigger glass boats just can not. I don't need a big truck to tow it, and the 25 is great on gas, and when you fish over 100 days in the spring/summer/fall like I do that really helps. I fish by myself most of the time on the smaller western Finger Lakes, and with me, and all my gear it moves along just fine. No I can't get from one end of Conesus to the other in 10 mins. but when I do decide to make a run I know I am not lighting money on fire via the gas tank. It's been a very good boat and I do not feel the need to upsize anytime soon. It was also enexpensive enough that I could walk in and pay for it.........no payments, afterall it is just a hobby and If I had to fork a couple $100 bucks over to the bank every month I would have far less $$ to fish with. Now when I fish a tx. I can put the $$ I win in my pocket insted of the gas tank and to the bank. And up hear the boat sits in the barn froml ate Nov-late March, I would rather heat my house and feed my kids than pay the bank for a toy thats not getting used.
There are alot of advantages to having a smaller boat, and if those reasons make sense to you and you also realize the things a small boat/motor will not do before you buy it you'll be happy with it. It may just be the little "bad attitude" I have in me, but it puts smile on my face to show up to an open tx. with my "little" boat that a lot of the guys turn there nose at and take there money home with me at the end of the day.
As far as the quality of the Tracker, I have had ZERO issues, and I use it probably alot more than most, and I don't beat it, but I don't treat it with kid gloves either. Any thing that is broke/worn out is my fault. And that's a small list at that.
