Its interesting to say the least. In marine applications, it seems direct injection 2 strokes are falling out of favor as 4 stroke outboard are getting lighter and more powerful. Yamaha and Mercury have discontinued their HPDI and Optimax DFI 2 strokes in favor of 4 strokes, not sure how much longer BRP will hold out with their E-Tec line. I dig 2 stroke engines, but DFI 2 strokes are far from what I would consider optimal. Perhaps in a racing setting where the engines are constantly torn down, rebuilt and small details are fussed over, they might be ok. I know of countless owners of DFI 2 strokes who have dealt with engine failures since these engines run exceptionally lean and with minimal oil. I currently own a Mercury Racing 250 XS on my bass boat. It's fast, but I miss the simplicity of my old Mercury 225 EFI. It was easy to work on and was stone cold reliable.
