That's a very common misconception, because modern wide beam hulls designed to handle the weight of 4-strokes are so inefficient compared to Moesly's patented Variable Deadrise Hull! That's why you see lots of new 8' beam 20' hulls with 200 hp on them! The VDH hull was tested extensively at Mercury's Lake X in the mid-60's and found to be 10% faster than conventional deep-V hulls with the same weight and horsepower! The 19/20' hull was designed in about 1964 for the largest outboards of the time, which were the 260-300 lb I-6 Merc and V-4 OMC's, of about 100 hp (rated at powerhead, so about 10% less at the prop!), so it actually rides and handles best with the small (by today's standards) and less thirsty light weight motors. Many were sold new with 85 hp 2-strokes on them! The Tracker models are actually a bit longer and heavier and have 25" transoms, so'll they'll handle a heavier motor a little better, but all of the 20's are relatively light. They ride well with their relatively slender 7'6" beam, but they will start to go airborne in seas of about 3' at speeds over 20 kts due to the light weight, so if you plan to run offshore very much, less is more! In those conditions, you won't be able to use much more power than it's already got!
