YAM took a whole page of my owners manual to tell me just how clean these 4 strokes burn fuel. They even put a special sticker on the cowling. There is zero evidence of fuel sheen or oil on the water when the engines are running. Zero smoke. The plugs are clean clean clean when I pull them. If I were running a two stroke my opinion would be different.
Ringfree - I just don't buy it. Figuratively or literally.
