I think you'll do OK since my motor's even older (1970!) and the aluminum prop works fine, especially here in South Florida where you have to run quite a bit in the shallow waters of Biscayne Bay until you can hit the pass and get out to deeper waters. Going through some shallow areas I've already banged up the prop in sand, small stones, coral and such. The aluminum absorbs the shock a lot better than SS and it's cheaper to repair or replace the prop than the lower unit! Good luck with yours!
