Re: 16ft bass tracker w. 25hp
My buddy has a 91 Tracker T17 with a 25HP 2 stroke and it moves pretty good.. The older Trackers were made a lot lighter than the later models, you'll plane out but your hole shot won't be the greatest. Figure about 25mph max with 1 person in the boat. That should be fast enough for weekend fishing trips. If you want more speed, go with a 50HP 2 stroke.
That year Tracker is lightweight and has a fast hull. Factor in the fact that the motor is a 2 stroke which is lighter than a 4 stroke. If you balance it out just right you'll plane with no problems, i.e. watch your fuel tank level, store your batteries on the port side, fill livewell only when needed, etc. I'd recommend getting a hydroplane for the motor, it will make a big difference.
I have a 92 T17 Tracker with a 50hp Evinrude and it gets up to around 42mph with 1 person, empty livewell and minimal fuel in the tank. I'm running a 19" pitch cupped prop. This thing is fast for a Tracker.
With a Tracker, you'll learn to be aware of the balance. They're really light boats.
