Has anyone had any experience with a CDI feathering prop? This is a true feathering prop, not the plastic one they sell for the 2GM 20. I have one on my H33, and it seems to work well, but even though CDI shows it on their web site, they don't seem to want to send any information on the prop. It has two blades attached to a metal hub, that appear to be some sort of plastic or very dense nylon, and are adjustable as to pitch, and feather when sailing - pitch reverses when backing, so has good backing performance, although strong prop walk. What I am interested in is if anyone knows anything about this prop, and especially a source of spare parts and instructions?
