Prop question

[yam911]

Most interesting. On another forum they go on and on and on about how much more torque a two stroke has than a four stroke.

Along comes Yamaha and offers a vented VMAX propeller for their HPDI's, to help it to spool up, and then Yamaha offers a non vented VMAX propeller for the SHO model because of all of the torque that it produces.

Leaves one sorta confused.

So what is your professional opinion?
Is there a timing change (up or down) on acceleration?
Just curious.
