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.

In a full bog down situation, that engine is capable of drawing 22 gallons per hour.
Is it possible the motor could be mounted too low on the transom? Pictures and new thread.

Any suggestions on a prop for my V-21 200 Yamaha 2-stroke? I'm new to the serious boating stuff been aroud them all my life now I'm paying attention. The aluminum prop that came with has no stamp on it indicating what pitch or size it is. I hit 48 Mph on the GPS full out if the tack was right it was 5000Rpm and 33 Mph at 4000 Rpm. Does this sound right or not
 . I want to get to try and find a SS one I'll be doing day trips out to some Islands mostly. I'll be going out with my father tomorrow to see if the tack is on or not hope fully I can pin down some more accurate info.
