Not really.
The only way I've ever seen them was the way mine was .
The O-ring around the bowl came to within a 1/4 of inch from the outside of the T/A
The others have had Jacuzzi's in them.
I actually got the opportunity to go look at this boat .

It had a Jacuzzi with the energizer kit on it.
When I went to see it, it was having some work done to it so it was in pieces.
That boat acually has 2 small rudders on either side of the intake that turn damn near 45 dgrees.
1" stringers, and a foot operated ride plate that also operated the diverter nozzle .
Years back when it was originally rigged by Jack McClure , the only diffrence was that the nozzle was fixed.
So it got all of it's steering from the 2 small rudders.
2002ish Tim Demerit (Nuckin Futs) drove it in the Parker 300 and he said it turned like a flat bottom and from what I gathered he liked it over all.
That coversation was a few years ago so I cant really remember how it went.
Jim Rich said it was a great boat, just the slowest thing in the world.
Josh ran across one also with a Jacuzzi but not set-back either and Ray (IIRrebel) has one with a Jacuzzi
For what it's worth Tom, the builder of the Saguaro bought the molds from Beisemeyer and was also good freinds with the owners of Kona boats.
The deck has alot of Kona designs
The bottom has more Beisemeyer influence than Kona.
Jim Brock I want to say picked up the mold to my boat after Saguaro's owner died in a plane crash and probably knows more than I do about it.
He told me lots of good stuff about them but I dont think a set back was going to be a huge benefit.
I could only see it making the boat more stable at higher speeds.
I can go on and on .....
My favorite part is how these two pictures came out almost 40 years apart.
