Tox, I paid $215 bucks to have my prop worked by DAH propeller and that included shipping costs. In my opinion it was worth every penny and then some for the work that was done. It improved every aspect of performance. Before the work was done my boat was a dog out of the hole, porpoised a bit at slow speed, blew out in turns and sometines would slip in rough water. Now it rockets out of the hole, no porposing( i can even trim out some at 20mph and stay there), very little slip in turns, great bite in rough water( better then a 4 trophy blade i tried) and i picked up 2mph over stock. I also do a little better on fuel because everything is more efficent, its not a big increase in fuel milage but enough that i noticed it. I think it was worth every cent of the 215 i paid and then some. I dont think i could ever run a stock out of the box propeller again, thats how much improvement was made.
