You'll love the engine, i have the 2008 150 Etec on my Cruise Craft Explorer and it works so well.
Fuel efficiency is awesome, uses less than half a tank going to Browns and back where as my old 2 stroke would chew just about a full tank.
And quiet, emmission free.. just a very good engine that i am super happy with (Thanks again to Huett Marine)
