Hi and welcome to the forum mate.
The boat is a little old but looks very good condition for the year, so should be fine especially if you have the confidence of a well serviced engine (check for proof!).
The Taskforce is a cracking boat, many commercial users would recommend, however a vastly different boat to the one pictured.
I my opinion, if you want an out and out fishing boat then the Taskforce will knock spots off the one shown, but if you wany ANY comfort then it wont be for you.
The taskforce will be faster, less comfort on the move and very little if any cabin comfort (most are open/small cuddy), but for fast offshore work, great build qaulity and duarbility the taskforce will stand the test, very stable at anchor too.
I would imagine the taskforce will look a little "rougher" and more "used" or painted gel coat etc, they do hold their money through repuatation so it will appear you are getting less for your money, but with a good 90HP - certainly quick enough.
I owned a Taskforce and it is a good, tough, out and out fishing boat, not one for the misses and a slow cruise so to speak set against the one pictured.
You personal choice of what you need will set you right, just expect to "appear" to get less for your money with a taskforce but resale value is relevant.
You sound like you know what you are doing when you mention transom condition etc so I am sure you will know what you are buying condition wise, just make sure you understand if your heart is ruling your head - ie: what do I want from a boat.
Best of luck and don't forget to let us know how you get on, and then, like everyone does, come back and ask all those needed questions - most of all, Have Fun!
