I think we have seen the last for Evinrude, except, perhaps as some unrelated marketing scheme, as it is still well-known.
I think 2 cycle outboards will go nearly extinct, in the US, as 2 cycle motorcycles have. Other parts of the world will likely still have them.
To be fair, there is no good reason to have a new 2 cycle DI motor these days, IMO. They are nearly as heavy as the 4 cycle motors and as complicated, electrically. They do not have a HP rating advantage over 4 cycle motors, and boats are being built to carry the weight and size of 3 and 4 four cycle high HP motors.
It is also a status thing. My neighbor had twin 225HP Mercs (4 cycle), that went bad. Replacement is $40K or so for new motors. He would rather not have a boat, than repower with cheap 2 cycle 200HP Mercs, which are plentiful.
I would go with the smoke...but that is just me....
