First, if you are unsure what you want, think it through this way. You seem to be really unsure of what is most important to you in a boat. Never go smaller for speed you will regret it. Pick the type of boat first, ( aluminum, fiberglass, tiller, side console, dual console), based on the waters you fish. Are you fishing small creeks and rivers, small to mid size lakes or big rough water lakes and tidal waters? Now look at those choices and determine what size is safe to run there and last how much horse power is needed to make it perform properly. If your boat is safe and has enough deck space now, then almost any new boat in similar size will have a wider hull, more storage and perform better than what you have now. If you are interested in another aluminum boat there are a bunch of really good ones including the new Trackers. If you looked your boat it is 17 feet long with a 71 inch beam with a 60 hp max. A new Bass Tracker Pro Team 175 TXW is 17 feet 7 inches long with a beam of 89 and has a max rating of 75 hp. If you choose a 50 hp 4 stroke they estimate top speed will be 34mph, a 60 is estimated to go max 37 and with a 75 hp 4 stroke they advertise a top speed of 40 to 41 mph. Now that is a much bigger boat, it is 7 inches longer but 18 inches wider and the beam is carried much further forward than on your boat. It is expected to go anywhere from 5 to a max of 12 mph faster, carrying a much more comfortable sized hull. These numbers are found directly on the Tracker website. Go to their website, drop down the mod Vee tab, choose 2017 models, then Pro Team 175 TXW. Next look under "Motors" tab. Now I am not saying to get a better performing boat you should go out and buy a new one ,there are lots of these "newer boats" (that is compared to your) that may be only a few years old and available for sale used at a decent saving. This is no knock on the boat but rather a statement showing lots of anglers buy this popular boat and then in a few years decide to sell it and move into a large fiberglass bass boat. I am not trying o talk you out of the excitement of ordering a new boat either. If you do you can choose higher end electronics and some other goodies. One other thing is that even though these newer boats with bigger engines go faster the fuel they consume may be not much different than yours does now.
If you consider a Tracker Pro Team 190 that is a boat measuring !8 feet 7 inches with a beam of 89 inches. Its max hp is a 115 four stroke and it runs an advertised speed of 46 mph. Now that is hauling a much bigger hull with bigger decks, storage and seating room than yours. I am not even suggesting to go with a Tracker I am just comparing what they make now compared to back in 97. Take a serious look at Tracker, Triton, Ranger, Lowe, Xpress, Alumacraft, Polar Kraft, Lund, G3 nd I have probably forgotten somebody's toys.
