I've been searching the web for a supplier of Kort nozzles, but all I can find is custom jobs for ocean going ships. I did find www.propguardmarine.com, but what I'm really after is known as a Marin 19A type nozzle, in a size of around 15" ID. I would try and turn a nozzle on my lathe, but the lathe is a couple of inches too small. Has anyone given thought to fabrication methods for this other than machining out of solid material?
thanks,
Alec
