I have one on my 210 CC come out of the hole and on plan instantly, they work well. If you hit something with a stainless steel prop it will not give, if you run shallow water or across the bay in mosquito land I would stay with aluminum. I file the nicks out of mine, and for around 60 bucks I can get my redone, filled in. I always carry a spare with me and cotter pins and nut.
