Prop Shaft

[ogshotgun]

I am probably wrong on this.
A hydro shaft never drags in the water so they can run huge shafts without drag
The vdrive or wdrive isn't way forward in the boat so the shaft is short, less spaghetti action going on.
A hydro prop has a shit pile more slip I believe also.
There's almost no boat touching the water, zero resistance on the prop and shaft, well not zero.
A hydro and a circle boat are apples and oranges.

yes apples and oranges
shaft doesn't touch the water , strut just above it , front shaft is bigger than the prop shaft
the boat hulls is a foot out of the water , the w drive is right against the capsule , but there is a mid shaft about 30" long than a prop shaft about the same length running two couplers one off the w and one under the boat
as far as slip i don't know but we grease the shit out of the props to make them slip so the boat doesn't slip
