Re: 6r74c prop choice differences

You realize of course that is not the stock 9.5hp prop? As for which is better for your situation, try each and see what the results are. The 3 blade will give more blade area for more thrust if you have the horsepower to turn it. But it may present such a load on the 6hp engine that it can’t rev up to it’s potential. Try, see, and report back. My money is on the stock two blade. But I’ve been made a monkey of before.
