Thanks for the kind words!<br>

The nozzle/shroud has an inside diameter of around 303mm at the
narrowest. Both the nozzle and the prop are replacement parts for
the commercial DPVs made by dive-xtras. The shroud cost 70.50$,
while the propeller kit is 67$. I bought it directly from dive-x
here:

A nice feature with the propeller is that it has variable pitch, and
that the blades can be replaced individually. However, the blades
are plastic and I'm not sure how well they would survive an impact
or entanglement. The scooters from dive-x have a clutch to save the
prop in case this happens. Here is a drawing of the propeller
assembly used by dive-x:

<br>
I bought the motor from <a class="moz-txt-link-abbreviated" href="http://www.goldenmotor.com">www.goldenmotor.com</a>. I'm not impressed by
the build quality, but it was very cheap and hopefully it will work.
They also have 650w and 800w editions of the same motor, perhaps
this would be suitable for use in a submersible?

<div><br>
</div>
<div>Welcome! That is a nicely documented project, and
very timely since we recently had threads about kort
nozzles and magnetic couplers. Quick question... could
you tell me what diameter that nozzle (aka shroud) is
and how much it and the prop cost? I'm curious about
adapting those to trolling motors.</div>

I'm currently designing and building a diver
propulsion vehicle with a magnetically coupled
drive. I will use a 48v 500w BLDC motor intended for
electric trikes, powered by 4 SLA batteries coupled
in series.<br>
<br>
I'm posting my progress at my personal website, <a

<br>
Anyway, hope you find this interesting! I hope to
build a submersible in the future, but this will
suffice until I have the funding and knowledge
needed :)<br>
