I get 2100 at low end and 13000 tuned down to 12,400 for high end with my 46AX. You shouldn't need any more RPM than that.
State your prop size else you're post is useless.
I spin a 11x6 prop on my 46and it's 2800 or so at idle and about 12,200 at full open. this is a LOT of power for my 4*40..
12x5. Lots of pull, and still lots of speed (everyone says my Dolphin is a rocket!)
