Re: direct drive
Does direct drive mean the prop turns at the same speed as the engine?
On larger, heavier boats it is more common to find a reduction gear of, say 2.x:1. With the reduction gear a larger prop can be spun giving more thrust.
That said, there is nothing wrong with direct drive transmissions if the prop can be sized to efficiently move the boat with some power left over for when needed. You would need to do a sea trial under power to asses how the drive train performs.
