Re: 8x4 or 7x4 smaller prop= more revs in water versus larger prop and yes, you will lose some speed, but then again longtails aint built for speed anyway.

Re: 8x4 or 7x4 I think at 3700 you should be good, I would rather have more speed and keep the r's down a little. Valve springs will last longer too.
