I have an aluminum prop which works awesome. I go as fast as I need, and the acceleration is generous. I would like a stainless so I can mow over anything and everything! hah, kdding of course...but I would like a SS for durability, and if I can gain some performance also, then great... Here's the prop It runs 5880rpm at a touch over 30 with me, my kayak, and fishing gear aboard...it ran 5780 and a little over 28 with a passenger and gear...I'd like to keep this performance or possibly improve...The closest 3 blade ss prop I can get on getaprop.com is a powertech 10X11 ...should I get it? will it be a big difference between my current 9 7/8 X 11 1/4?
