Customer photo review of Suzuki ECSTAR Lower Unit Gear Oil SAE 90

Recently purchased new 2024 Suzuki outboard for my pontoon. Getting ready for initial break in oil service. Wanted to use OEM oil, found Boat Max website and their oil was about $14 a gallon cheaper than any oil I could find locally! Placed order and it was delivered to my house 4 day's later. Very easy and convenient. Will definitely use them in the future.
