[QUOTE="bellman, post: 399200, member: 20102"] OK, I finally got around to taking the best pics of my pump/prop/rideplate/intake grate setup that i could. It also shows the steering and trim system. I also took a couple of pics of a stock stator section so the differences can be seen. Keep in mind The pictures of the mag pump are taken through the exit and steering nozzles from the rear because I'm far too lazy to take it out just for a few pics. Hope this makes all this easier to visualize. This is a setback 12 vane 140mm. Notice the short length & very gentle curve of the vanes. The stock stator vanes almost look like the letter j compared. There is also a considerable amount of tuning done at Skat after casting where every vane is shaped and all flash and obstructions are cleaned up. It's design is much more efficient because the water is not forced to make such sharp bends and it also is passing over thinner, more hydrodynamic vanes than impede water flow much less. Charles P.S. You can also see the rideplate I made. It's 1/4" al and is about 2" longer than the transom and nozzle. I've found myself floating backwards into rocks many times and it would crack the steering nozzle into a million pieces if the nozzle hit first. This should take the brunt of those hits. It's mounted with an inch thick piece of super hard rubber between it and the pump tunnel so it can absorb some shock and not disturb any adhesives. [/QUOTE]
