That sounds about right. When I was looking at various boats, the 150F was my motor of choice for most of my options, but just about every dealer who knew his business felt 52-53 mph was probably going to be the tops for this engine. All agreed that the regular carb 150 or the 150 VMax HPDI would probably get to 55mph goal I was looking for. Since I did not want the carb engine and the 150 HPDI was only available in short shaft, as well as the 175, I went to the 200Z. My previous boat ended up disappointing me with the top end being about 5-8 mph less than I had hoped for and I didn't want to go through all the trouble of rigging and purchasing a new boat to only be possibly disappointed again. Besides, one of the other boats under consideration was the Pathfinder 2000V, and their forum is loaded with disappointment over the fact their owners cannot put a 200 on their boats due to the manufacturer restricting the max hp to 150. I figured here is my chance to have a similar boat and be able to get the 200. I have always been a max hp person anyway. The old "You don't have to use, but it's there if you need or want it."
The test boat I drove with the 150F was green as I said before and my previous boat had the 115F which loosened up around 15- 20 hours, so the numbers you are showing would be what I would expect.
