My parents Pre-Tracker 1987 18SF when it had a 1994 150 Johnson Ocean Runner did 47 @ WOT. A few of observations:

Weight of that boat is more than Potter or Tracker 18's due to materials and glass thickness

The 1987 boat was barely self bailing with the 150 with the original deck height and weight distribution

My 1989 Tracker 18SF that I sold was a lighter boat (plenty strong) and had the batteries under the console with a 358 lb 130 Yamaha.

Those 2 18SFs sat totally different in the water due to weights. I am more prone to less weight than to more power because of the differences in ride quality. That being said, those 2 configurations would be great. By the way.....my parents kept that 150 prop after the motor took a dump, and now they are selling it because they are moving this month. PM me if you are interested.
