    Great gear lube!
    By  JEFF,  a  Verified Buyer  from  Highlands Ranch, CO  on  November 01, 2021

    Describe the issue

    We've used this gear lube in our previous boat and our current boat. Our old boat had the Alpha One in it and the new one has the Bravo Three. We've never had any sterndrive issues with either boat. They both ran nice and quiet and every time I changed the lube it still looked like honey.
    Bottom Line
    Yes, I would recommend this to a friend.
