We got the 5.3 in our 2016. It is a much better option than the 5.7 in the nautique. In the 2017 boats, the old 6.0 is the standard motor, with the 5.3 and 6.2 DI motors as upgrades. We all agree the 5.3DI is good set up, but is it better than the 6.0???? What are the 2017 promo guys going with? 5.3DI? old 6.0? or 6.2DI? The torque numbers are slightly higher for the 5.3 over the 6.0
