    no other can compare
    By  MICHAEL,  a  Verified Buyer  from  Pensacola Fl  on  January 03, 2025
    have been using this product for years and I'm very happy with this gear lube. It says what it supposed to do easy shifting and no ware on the parts even if water does penetrate the system. when I drain the lower unit there is no metal filings on the drain plug that tells me it is doing its job.
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent
    By  STEVEN,  a  Verified Buyer  from  Quebec  on  November 01, 2024
    The best that any out drive and lower drive any marine engine could get, would be good to have 1 liter bottles instead of 1 quart( as often you need 2 litres, and i have to buy 3 instead of 2 to top off)
    Bottom Line
    Yes, I would recommend this to a friend.
