It applies, have vent/cav plate at the water's surface. Typically those with OB brackets can just run them a biut higher, as the water exiting the hull goes up (allegedly 1" for every 12" of setback) as it leaves the hull bottom.
Remember, with a stock OEM, non-premium prop, you can't run an OB as high as you could if you had a premium design (rake, cupping or both, or a 4-blade) wheel installed.
My #1 boating pet peeve is that boat's wear the wrong prop most of the time, even when rigged from the dealer.
My #2 boating pet peeve is that most dealers mount the OBs too deep ...
