All of this talk of two stroke ban's really sucks, But has been around for a long time. I was working for Yamaha and Bombardier back in 94 and we were affraid of ban's back then! Really a shame because the 20.4 stoker is bad-ass with a 2.5 on the back! From what I have been told (and im still doing more digging)If you get the motor now, it will be grandfathered and wont be a problem. But , if I were you id do some research also....Great boat good luck......
