    Just did the first 100 hr service on my new Yamaha VF90. Manual called for 90 but this 75w-90 is all that’s offered from Amsoil. Hopefully it’ll be fine.

    The best available
    By  JEFF,  a  Verified Buyer  from  Colorado  on  November 23, 2022
    Amsoil is the only gear lube I'll use in our sterndrives. Our old boat had an Alpha 1 and our new boat has an Bravo 3. It's comforting to know we can count on Amsoil to get us through another problem free year on the water.

    Yes, I would recommend this to a friend.

    OEM Full Synthetic Equivalent
    By  MICHAEL,  a  Verified Buyer  from  NJ  on  November 01, 2022
    The lower unit of my Yamaha SHO outboards is always filled with Amsoil gear lube. It exceeds Yamahas specifications for lower unit oil and it the perfect replacement for OEM options. As a bonus I have noticed less noise since I started using the lube when placing the motor in forward/reverse.
    Bottom Line
    Yes, I would recommend this to a friend.
