I'd say that sounds about right, most 80 to 90 horse don't go much over 30 to 35 mph, I had a 60 horse that went 22 to 27mph. Depending on your prop you might get a little more speed but it would likely be no more than 2 to 3mph but that is just my opinion, I sure others will have another point of view.
