It's a 25-40HP outboard. I don't have numbers, but the bulk of completing conventional engines in that range are going to be two strokes. They aren't selling big motors yet.
Most 25-40 HP outboards sold today are 4-stroke. The only significant brand that's still 2-stroke in the US is Evinrude, and it has < 10% market share.
I think it is illegal to sell >= 25HP two stroke boat engines in Europe. When we last bought one they only had four strokes.
