I'm getting the impression you are getting hung up on nothing here.
Have you been out on a 6.5 meter rib with a 150hp four stroke? I suspect you would be staggered at how fast it accelerates. How fast it will go, probably a lot faster than you'd be comfortable travelling in anything other than mirror calm water. It will
effortlessly pull two skiers with the boat three up and all of that at less than a litre a mile. It's true that a two stroke will be marginally faster accelerating (if properly trimmed and prop-d)
but you'd likely be buying an engine that's out of production from a manufacturer that has consciously discontinued production of two stroke engines or, worse, a manufacturer that has gone out of business.
