Marine Grease 3 oz Cartridges, Case of 10

Keep your boat, trailer, and gear running smoothly with a proven marine-grade grease formulated for the toughest on-the-water conditions. This heavy‑duty grease uses an overbased calcium sulfonate (OBCS) thickener with tackifiers and anti‑wear agents, so it stays put and keeps critical parts protected even when constantly splashed, submerged, or pressure‑washed.

Designed for real‑world marine use, it’s ideal for boat trailer wheel bearings and hubs, trailer chassis fittings, outboards, steering linkages, winches, and other pivot points exposed to moisture. The adhesive, blue grease clings to metal, resists water washout, and helps prevent rust and oxidation, extending service intervals and component life.

Behind the performance is a robust formulation that provides durable film strength under shock loads and extreme pressures. The distinctive blue color helps you spot fresh applications, and the 3 oz cartridges are sized for mini grease guns—perfect for toolbox, dock box, or tow vehicle. Note: not recommended for centralized dispensing systems.

Packaged as a case of ten 3 oz cartridges, this set makes it easy to service multiple fittings before every trip and keep a spare on hand. Formulated and filled in the USA with domestic and global components, it delivers the reliability and pride you want when your weekends on the water count.
