Not much on fuel economy, but pretty dang durable engines.
Does anyone know if the Mercury EFI has any common problems? The 1997 Mercury 150, does it get any better fuel economy than the the original? I know not as good as the optimax though.

I have a 1995 model EFI purchased new 4/95, besides water impeller's it's never been worked on. Don't run it a lot anymore but still glad to have it and consider it a goodun.
