2024 ACE 1630 engine specs

I read on Watercraft Journal that the ‘24 300’s share a lot of engine parts upgrades with the new 325’s. Not all parts, but several. Anyone else see this? It only matters to me because, if true, I MAY consider a tune increasing RPM. Kevin Shaw went on to say that Rotax must be getting a helluva deal on those parts.
