I just installed my new OJ 14.75 x 15.5 prop last night and ran it today. It was a huge improvement over the stock 14 x 20 prop. While I was changing it, I noticed a couple things. One was my old prop was bent on the back side a couple inches from where it mounts on the shaft. I did not even notice this until I removed it. The other was a blue plastic washer on the shaft. I was wondering what it is for and if it is doing any good. I did notice there is some kind of rubber gasket behind it in the shaft itself that looked to be a little cracked. Unsure of what the gasket is for too.
