Great product at a reasonable price
Size: 32 Oz Quart Style: 90W Hypoid
At SailQuest.ca we use Star Brite products almost exclusively on our yacht. We have found them to have superior products that do the job they are intended to do, quickly and easily... the FIRST time around! Despite them being marine products, and products that work really well, they are very reasonably priced. This gear lube is used for the lower end on our outboard. The outboard is a required piece of equipment on board so we looked long and hard for a good product to keep it safe in this harsh environment. ... show more

Great Longevity
Size: 32 Oz Quart Style: 90W Hypoid
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.

Great price & quality
Size: 32 Oz Quart Style: 90W Hypoid
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.
