I have 07 Etec as well. Lower unit has been changed to updated unit but other than that great motor. Unbelievably quiet oil consumption with XD-100 is next to nothing. I came from a Mercury and the oil usage is incredibly less in the Etec. Probably not quite as fuel efficient as the Merc but throttle response and quietness Etec hands down. I do quite a bit of idling with the side scan have had no issues yet. 400+ hours.
