STAR BRITE Star Tron High Viscosity Lower Unit Gear Lube 80W90 - Anti-Wear, Rust & Corrosion Inhibitors, Ideal for Outboard Motors & Stern Drives - 32 OZ (027032)

Great reliable gear oil. I use it in my Yamaha SHO 115. It cost less and easier find available. With quick delivery.

Bought this for lower unit lube in my small outboards. Seems like good stuff so far!

After a year in my boat I just replaced the fluid. The fluid looked almost new after 1 year of use. Definitely recommend this fluid and I will use it again.

Could find no where locally and needed for my boat. great price and delivered next day. Awesome.

Seems good

Seems like a good quality lower unit oil.

Purchased this high-viscosity oil for my bow thruster. This brand also has “EP” (extreme pressure) additives which usually is found only on the more expensive brands.

Works great
