We had a Campbell prop on Grace for a number of years and it performed quite well. But we replaced it with a Brunton Autoprop and were immediately aware of more power, both forward and in reverse. We replaced the prop to maximize fuel economy and I think it's been a wise choice. I have been impressed with the Autoprop's ability to get me off groundings when I thought for sure I was going to get to know the local TowBoatUS guy.
