I have a Tahatsu 6hp kicker I recently purchased on my CD-22 Cruiser.
I'll copy some information I placed in another thread that might help you:
... I have found that at 3/4 throttle, or at about 4000 RPM I'm getting about 4.5 mph on the GPS. Run it up to full throttle, which right now is only giving me about 4400 rpm, and I can just get to 5mph. ...This motor is suppose to run 5000-6000 rpm at WOT. The prop that came with it is a 7.8x8 (8 being the pitch.)
...The Tach I'm using is a nice little one I just recently purchased. Hardline HR-8061-2.

Seems to be pretty accurate. At least if the Kicker is idling where the factory says it's suppose to be. (Around 1300, which is what the little hour/tachometer reads when it's at idle.) (I ended up running the wire thru the grommet where the front shifter rod comes out, and then tie stripped the gauge to the bar across the front of the motor.) As I break the motor in, I'm getting about 4 mph at 3/4 throttle, which is probably where I would run it (or slower) while trolling. (Also, I don't really seem to gain much more speed by running WOT.) My WOT RPM concern is that if the engine isn't able to produce the spec'd 5000-6000, then perhaps it's working too hard with the prop that's on it. I did go ahead and order a 7.8 x 7 (one size down) Solas Prop from iboats. I'm hoping that prop works a little better...
I did get that prop, and now getting 5200-5400 rpms at WOT. Speed is about the same, max being 5mph. Colby
