we used to ski with a 3 cylinder volvo-penta 35hp o/b on a heavy 5m Morebas hard boat and it managed everyone thru their learning stages except for a particularly corpulent mate-but we did a lot of dragging him around in a sort of attempted drowning/colonic irrigation mode.
Good entertainment for the boat crew.
After that a 40hp 2 stroke Mariner was a vast improvement, and then a 50 Yam. So you should be ok....except that Honda o/bs are not noted for their get up and go, they tend to be the engines that you go and check the hp number on the hood cos its seems to be missing some hosses! You may need to shove the observer up into the bow to aid getting onto the plane.
