I agree that a 4 cylinder would drop the weight, but a 200hp 4 cylinder is probably not the best idea. It will be a smaller liter displacement and might be sluggish on some boats. Some of the verado's bigger engines are 4 cylinders like the 200HP(all are supercharged to achieve rated HP's) and I've heard from some they don't have the pep that a 6 cylinder has on heavier boats. On light boats you cannot notice the difference. There is also a 6 cylinder 200HP verado. A few tests have been done and there are many differneces between the two, each has its own applications where it will be better suited, but a 4 cylinder has no place on a heavy or bigger boat. For this,I think going 6 cylinders is the only viable option. I'd love to see weights drop, but right now in the outboard industry, HP is the craze, not weight. I'm sure at some point the outboard companies will shave weight off as technology evolves.
