I am definitely missing something though, because by that definition a 19" would provide better accelleration AND higher top speed than a 17" rather than a trade-off.
I assume there are some fluid dynamics that come into play similar to HP and Torque, I'm just having trouble visualizing which pitch favors which.

A 19" pitch prop will have a slower holeshot versus a 17" pitch. Think of the 19" as highway gears and the 17" as drag gears.
On my 4.3L powered 18' Celebrity, I added a "whale tail" to the lower unit. At the expense of about 2 mph on top end, I get much better hole shots ( made a BIG difference pulling water skiers) and increased stabilty in rough water ( less rocking)
