EDP the 250 HO E-Tec is a fine piece of equipment and runs very well from what we can tell. The fuel mileage is not quite what the Mercury is, though comparable to the Yamaha from our observation. The performance can go to any of the three engines as they either one could be faster. We do think there is a bit more potential with the 250 HO though. Then there is the warranty and more to consider. BCB
