The Mooneys I have flown all had the electric gear, but I have seen the manual systems. In my Teal, the gear is similarly completely manual. It's a workout to move it, but as said, totally reliable, and simple to maintain. If the muscle required to operate the gear is tired, and you're flying by yourself, you can cheat a little, and bunt it over to half a G, and timed right, the gear comes up with much less effort!
