dont mean to question authority here..... 
but what are some of the differences between jetovator and a PD?
it seems i have a PD, but the controls of a jetovator. it has the little box with a power window motor in it.....etc.
my bowl is clocked....compared to the one pictured by the OP. those oil fill/drains....are both at top of bowl.
So... a Jet-o-vator trims first, and steers r-to-l second
When you do this, as the trim comes up (or down) the steering is affected, as it goes up, the nozzle will travel up AND to the left, if the steering stays centered. Steering input is required as trim is used. The technical term for this is: WONKY (Thanks Glenn)
On a Place Diverter, the diverter STEERS first, and trims second.
Having this setup, the elevation of the diverter (or lack thereof) does not affect the the steering, and further input from the steering is not required to maintain a steary (straight) course, with an elevation (trim) change.
On my JC pump with a PD, It has the electric over cable (jet-o-vator style) controls, along with the bowl turned 90*.
A Question for Glenn (or someone with more engineering skills than i) :
Could a standard Berk steering nozzle be 'cut and turned' 90* (between the steering and reverse pins), and set up the jet-o-vator at 90* to mimic the function of a Place Diverter? (steers first, trims second?)
