well, used the 15x16 over the weekend.....what a piece of crap
I still have no idea which way to go but I am definately putting the SS 14 1/2x21p back on. It outperforms the Aluminum 15x16 which question. I got the following numbers on the 16p prop over the weekend:
25mph - 3800rpm
32mph - 4200rpm
Couldn't seem to push much beyond 4400rpm so I didn't try. Absolutely sucked through the gas like nobodys business. I didn't realize that I have either a bad fuel guage or fuel sender until late on Sunday when I had to call Sea Tow to come and get my butt
I am going to start a separate thread about how to test those two components to see which one is bad.
