Hi kimcrwbr1.
Yes, that is the impeller. I was hunting for one six months ago and could not find one. After doing the rounds I found one in a boat shop in Perth gathering dust. As it was new, I made a cast in silicon and made some spares for myself. Word got out and I started receiving orders. To be blunt, the early units that I made were awful. I was given the wrong materials for the cores, the blades and the wrong epoxy. It was a nightmare that I don't want to repeat. I nearly threw in the towel but I found a different supplier that actually knew something about the materials I needed. I talked to some Engineers and finally received the information I needed to make these impellers the right way. It's been a long and rocky road.
Anyway, sorry to wander off track, but those are the same impellers. If you need one, I would grab one of those quick smart as they are getting few and far between. I plan to sell mine for around the $55 mark but I want to run one of these brass cored impellers in my own engine for a while before I release them.
All the best and have a safe and Merry Christmas.
Scott.
