Do anyone out there know if its possible to choose among different lower unit versions for Verado 350 Sci? Torquemaster vs Fleetmaster?

Can it be delivered with a lower unit with a torque tab ala Torquemaster? Or is it only delivered with a straight skeg ala Fleetmaster? I want to avoid the crabbing effect loosing speed at wot.
