Hmm what about stainless steel? Any better?
Used to be that aluminum props were basic design thrust devices that didn't have all the goodies you'll find in SS props....detailed up at the top of this screen under "Shop" and then go to "Props" and then go to the "Tutorial". Every one of these goodies makes for different outcomes.
SS obviously resists dings better and usually works the engine harder for a given dia-pitch since they are usually built to grabs the water better......a higher performance thrust solution. Some have ports under the blades that deliberately introduce exhaust gasses into the props slip stream to reduce the density of the medium allowing the engine to spin up faster which develops the HP-thrust faster so one can have a higher pitched prop for top end but get a good hole shot ( going from idle to having the boat up on the water) as the prop acts like it has a lot less pitch in the shot.
So folks like Turning Point (company) designed their "Hustler" model alum prop with all the goodies found in SS props less slightly thicker blades, much cheaper price, and aluminum material. Iboats sells them and SS props in that "Prop" section I mentioned above.
Getting the right prop for your boat is like shooting skeet with your eyes closed! It takes time, testing, and most of all usually $$$$$.
