E-J, I have seen many reports of 15s with F60s meeting or exceeding the 41-42 MPH that I can hit. And I am sure that if top speed was a priority, I could go faster. So the answer is "no" on whether 70 horses is really needed.
Your boat and situation is completely different. Unfortunately, the mandatory motor tie-in has resulted in you being a bit underpowered.
If you are currently running an aluminum prop you might be able to squeeze out a little more speed by changing to a quality, stainless one, but the improvement would likely be minimal.
