Agree. The 10hp will work, but I believe the Honwave 3.5 is rated to 20hp, so running with only half the rated power would be a compromise.
The 10hp would also need running at full bore to get reasonable performance so the 15hp could even be more economical.
I had a Suzumar 360 (practcally identical) with a Suzi 15hp and it was perfectly matched. 50% less power would have been frustrating after a while.
Hope that helps and welcome to the world of boating! Where are you based?
