Actuallly, with a Bravo drive you can turn it either way. Preferred is right hand. I expect you will probably want something smaller than the 26 but that is just a guess. Remember you will probably have a difference in RPMs to consider as well as the gear and horsepower changes. A Hydromotive prop will seem to have more pirch compared to a Bravo because of the way each is measured. A 24 Bravo should run in the vicinity of 70 depending on RPM and slip. Keep us posted.
