Your planing speed has a lot to do with how much your 175 weighs. Theses boats are designed for engines in the 300lb range. Any more than that and your min planing speedily increase. Trim tabs and a 4 bladed stern lifting prop will help. With one person and minimal fuel I would think your top end should be a little better than that. Go to you tube and search for "20 Seacraft minimum planning speed". That will give you an idea of what my 20 with a 2 stroke 115 yamaha does with a 15 pitch prop, 3/4 fuel and me on board. 3000 rpm, 13-14 knt min planing speed.
