    Yamaha Ring Free, in Merc 150 4 Stroke??

    Is it safe to use Yamaha Ring Free in A 2015 Merc 150 4 Stroke? I have a couple of bottles of ring free left over from my Yamaha days. Or Should I stay with Merc products?? Thanks..

    If you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!

    Years ago- the two products were virtually identical. Ring Free was reformulated, and now differs from Quickleen. I would recommend sticking with the Quickleen.
