Mmm the whole unit can be used plug ‘n play on a sub.

Inside Diameter of the Kortnozzle is 250mm or 9,84 something inch.
Protection grid forward and aft are just fix with clips.

Alec,
Don't count it out just yet, I went to Gavin via the link you provided and
had an epiphany! Note well the inside surface vs the outside surface of that
Kort nozzle!!
The model I quoted was solid material!!
I know what I'm doing tonight!

Sounds like David has just saved me the work of taking a 101 apart and
measuring it, thanks! As for the 101 prop size, it's 11" diameter.
Before you go off spending $760 on a nozzle, you might want to look up these
folks: http://www.gavinscooters.com/ I can't help notice Emile used a
Gavin, and it looks like Gavin Scooters, Inc. is right in your neighborhood.
Best,
Alec

Hey Joe,
I will send you my cad files on the Minkota 101 Saltwater. I have measured
my new 101s and weed 2 prop. I have also worked out the Marin 37 Kort
nozzel design and attachment to the thruster for use on the SeaQuestor
project. I will be most likely sending it to my fiberglass fabricator who
will cut the assembly in foam on their 5 axis cnc, ready for a fiberglass
overlay.

Ok gentlemen first round of quotes for a Marin 19A Nozzle only in ABS
plastic (White) for a 6" prop and not accounting for prop clearance is $760.
This is using FDM process.
Same nozzle in cast urethane,.. $ 3,700,.. what is cast urethane? Dont want
it anyway!!!
I need to know the exact diameter of a Weedless wedge 2 prop for a 4" motor
in order to get the quote exact.

Scott,
I use weights from a weight lifting set, the steel ones. They could go
outside on a peg so to speak. The only problem is you want them at the
bottom of the sub. That means hauling the sub unless you want to get wet.
Maybe a slide system. I thought the same thing to put the air outside,
that would kill my sleek and slippery-ness. :-)

Hatch closure from both sides deffenetly a good one. I would say adjustable
exterior weights. I hate the idea on chucking weights on the floor and then
sitting on them. I am torn between that and moving the hp air tanks to the
exterior to allow alot more room on the inside.
Thanks,

Joe,
Why don't you take a vote on what the best improvement would be for a k
sub or alike. My vote would be for a hatch closure from both sides.

Never thought much about doing it at small scale.
I suppose I would set up something like a wood lathe or a potter's
wheel
and work in some very soft material like low-density foam. Once I had
the shape that I wanted, I suppose one could pour a mold around the
master, melt or dissolve out the pattern and cast the final part in some
suitable plastic, or even in aluminum if you were ambitious.
3D printing seems like the ultimate way to do it, though - the accuracy
available is already better than what we would need, and if the inital
results are not perfect, making changes and printing out another
prototype is very quick.
