Since you did not say that you wanted to go the cheap route, consider what I did. I have one with a ys 63 four stroke. It is only slightly heavier than a 46 including muffler. The pump on the ys makes all the difference in running performance. Put a 12.25x3.75 prop on it and hover at 1/2 throttle. Works for me, but at $244.00 ouch.
