First time I have seen a small diameter chopper with so much pitch
Years ago a reworked a large diameter 22 pitch chopper down to 11 1/2 to run on a Pro 50.
I could not make it any smaller and the Pro 50 couldn't turn it.
Provided it is a 22 pitch.....it should work on 50 Tohatsu, 50 yamaha, 55 yamaha/mariner and 60 Mercury both 2 and 4 stroke.
Not a bad price.
https://www.ebay.com/itm/Signature-Chop ... 5b3fb10b4aIF you have a 50 hp Yamaha and can loan a 30 hp lower unit have Ron send you the 30 hp prop kit as well. Make sure you have plastic reeds in the 50 hp motor. The 30 lower unit really changes the performance of the 50 and you need the larger pitch to keep the RPM down.
