I found an aluminum adjustable pitch prop in the bottom of an old boat I recently purchased along with a 1963 Johnson 40 HP. I assume that it was once used on this same motor It has a half dime-sized nick out of one of the blades but it should be repairable. I'm not familiar with this type of prop and I haven't been able to find anything helpful on the net. It is stamped as "Omni-Pitch" and has an adjustment range from 7 to 15. Pics are attached showing the ID and the range of adjustment. If anyone can tell me anything about this equipment and whether it would be worth repairing I would greatly appreciate it.
