I know this has probably been asked but I couldn't find any results when searching. I have an Etec 200 and just got a Trophy plus prop but I'm looking for a Cavitation ring for. I see Quicksilver has prop seal part# 878421, I know it fits the prop and works with Merc lower units but will it work fine with my Etec as well? I have also heard that an Etec will melt the ring, is this true?
