i owned a machine shop for a few years, what do you think about machining  a set back adapter? has is been done? this to set pump back without cutting out intake? ie adapter between pump and intake.  go ahead-comments?

Honestly I see no value, the idea of a setback is to move the intake hole rearward to allow more hull to leave the water and keep the pump loaded (called flying the hull)...

What you are talking about can be achieved with a droop. Sorry for the "set back"                          And the pun  .
