Another possible source: Suzuki has a line of four-stroke outboard engines, 40-50-60-70hp, with efi. The 40-50 ones are 3 cylinder, 50 cu. in. and the 60-70 ones are 4 cylinder, 80 cu in. The picture I saw was of a four cylinder and had four injectors mounted on a fuel rail. -- Robert W. Hughes (Bob) BackYard Engineering Houston, Texas rwhughe at hal-pc.org
