Got a service bulletin from Mercury today.
The current 90 4 stk has a 2.07:1 gear ratio and they are going to change it to a 2.33:1 starting with the 2003 models.
They mentioned increased performance and quiet operation. They also mentioned that it will swing a 2" higher pitch prop than the current 90.
Interesting since Honda, Suzuki and Yamaha range between 2.30:1 and 2.59:1.

When is this new motor supposed to be introduced, and is it EFI?

The only thing the service bulletin addresed was the gear ratio change.
The new models usually come out in late summer/early fall.
My guess is that the only way it will be an EFI is if Yamaha makes the change themselves.
I don't think Merc would build an EFI unit for this block when they will have there own befor long.
