Specially formulated to meet the rigorous standards for MIL-PSF-2105E, API MT-1, API GL-5, MACK GO-J, MACK GO-H, this 80W 90 gear lube ensures optimal performance under various conditions.

Adhering to SAE J2360 specifications, it's the perfect choice for those seeking reliable, high-quality maintenance for their marine engines. DIRECTIONS: Refer to Manufacturer's Engine Service Manual for flushing and filling instructions. If none are available: 1) Remove upper and lower plugs on lower unit gear case and completely drain old oil. 2) Install fill tube into the lower hole. We recommend using STAR BRITE Lower Unit Quart Pump (#27410) or Lube Tube (#28600) for 10 ounce tubes. A 10 mm Adapter is available for conections that are not the standard 3/8" or 8 MM fitting. 3) Slowly refill unit with new lubricant until fluid appears at the lip of the upper hole. 4) Replace upper plug and tighten securely. 5) Remove fill tube from lower hole and replace lower plug. Tighten securely.

Review: Good product - Good product
Review: Gear lube - Very handy tube for adding or replacing lower unit gear lube in a small outboard motor. Cut small section of tube nozzle off and then nozzle fits tight in the filler hole with no leakage. Screw cap works well to seal tube when saving extra not used for another fill up. My vintage outboard (1970) called for this type of gear lube.
