Can't comment on the boat in particular, but I've seen people learn on anything from an 8' Optomist Pram, (myself), to larger keelboats, (J 24's). So I think you can learn on just about anything...
As far as motor size goes-my 7300# displacment 27 footer does fine with a 9.9-(I wouldn't want a larger motor, but some have mentioned going with a 15for similarly sized boats).
So I would think a 6 HP on the 23 footer ought to do fine. There's something I heard about not getting too large a motor, because then you run it in the lower rpm range most of the time, and you're more likely to foul the plugs, (I suspect this has more to do with 2 cycle then 4 cycle motors).
And then there's hull speed-you can only push a displacement hull so fast, no matter how big the motor, and with applying more power after you've reached hull speed, you're basically just using more gas and not going much faster.
And if I could get away with using a light 6 hp instead of my heavier 9.9 I would, because hoisting the 9.9 out off the transom for service is no pleasure...
