Two stroke DFI be faster out of the hole and to plane. Fuel economy is negligible difference with the Optimax a bit better. Where you will save with the four stroke over the Optimax is in oil. Optimax oil is pricey, $50 plus for 4 litres. 4 stroke be quieter and probably troll a bit better as well.
