I'll also vouch for the Max Prop; you should be able to find a lot of information on it and the Auto Prop by searching older posts here at Sailnet (I find doing a Google search with " site:www.sailnet.com/forums" appended works well --- eg. MaxProp or Autoprop?
One thing I like about the Max Prop is that it's quite effective when backing the boat out of the slip (its blades reverse direction so it has a good bite on the water) and has significantly reduced prop walk compared to the same boat with fixed 2 or 3 blade props. This can be very helpful if there's a good crosswind at your slip or for other tricky situations. I've read that folding props are poor in this regard.
