I have twin 200 Etec's 2007 on my boat, At the end of last year I ran on a sand bar and had to have the lower unit dropped and new impellers, and everything flushed. Put boat back in the water ran to dock (100 yards) put motor up noticed green lube dripping out of the high speed water intake holes on front of the lower unit on the starb. motor. Bringing back to marina that did the work hoping it's just a gasket that didn't seat, but anyone out there have an idea or sim. problem?
