[PSUBS-MAILIST] Diver propulsion vehicle project

[Jon Eide Pettersen]

Thanks for the kind words!

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: 
http://www.dive-xtras.com/cart/pc/viewPrd.asp?idproduct=42&idcategory=7.

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:

I bought the motor from www.goldenmotor.com. 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?
