As far as top speed, honestly I'm not sure yet. With the 115 Opti, we've had it up to 45 MPH at somewhere around 5000 RPM. It may have more speed, but I've been waiting for some nice calm water to really try it out. It seems to take the waves just fine, but the only experience I have is my father's previous jon boat and an uncle's fiberglass fish-n-ski. Its definitely not a jon boat ride! I was pleasantly surprised with the ride quality. It is all aluminum, with many of the others having wood decks and flooring (from what we found). Hope this helps.
