Boat Lift Hoist Grease — BH-USA
This waterproof grease is designed to resist saltwater exposure while maintaining lubricity at elevated temperatures. It helps prevent transfer of grease onto watercraft, reducing the risk of staining or slippery surfaces and protecting lift components from corrosion and wear in harsh marine environments. Its formulation supports long-lasting lubrication for gear hoists, pins, and bearings integral to boat lifts.
STAR BRITE Wheel Bearing Grease — 026014
This marine-grade grease is engineered to protect trailer wheel bearings from saltwater corrosion, salt air, and atmospheric chemicals. It’s a versatile option for winches, hinges, pumps, and anchor reels in addition to bearings, offering a wide temperature performance range from near-freezing to hot summer days, ensuring reliable lubrication in varied marine conditions.
AtomLube All Purpose Grease 2-Pack — 14 Oz Tubes
This premium all-purpose grease blends heavy-duty, multi-purpose, and marine greases into one versatile option. Made in the USA, it provides long-lasting lubrication with good oxidation resistance and washout protection, suitable for boat accessories, wheel bearings, and other marine and automotive fittings used around lift systems and trailers.
STAR BRITE Marine Grade Wheel Bearing Grease — 14 Oz
Designed for marine environments, this grease provides excellent rust and corrosion protection from saltwater, salt air, and atmospheric chemicals. It’s suitable for trailer bearings, water pumps, hinges, pins, winches, and anchor reels, with a formula that resists wash-out for lasting protection during exposure to water and weather.
Sta-Lube Marine Grease for Boat Trailer Wheel Bearings
Sta-Lube’s marine grease is formulated for water resistance and protection under severe water conditions. The 14-ounce cartridge is designed for boat trailer wheel bearings and marine hardware, offering good protection against rust and corrosion while maintaining lubrication under splash and spray.
STAR BRITE Marine Grade Wheel Bearing Grease — 14 Oz
This variant emphasizes superior protection against rust and corrosion from saltwater and atmospheric chemicals. Its water-insoluble properties resist wash-out, making it well-suited for boat trailers, water pumps, hinges, pins, winches, and anchor chain reels, particularly in marine-duty lift systems where moisture exposure is constant.
Buying Guide: Key Purchase Considerations
Purpose and compatibility: Match grease with your lift components, whether bearings, hinges, or winches. Ensure the grease is suitable for water exposure and high temperatures common in marine settings.
Water resistance vs wash-out resistance: Some formulations emphasize water resistance, while others focus on resistance to wash-out. Marine environments require both, especially near saltwater or spray zones.
Temperature range: Lifts can heat during operation. Choose a grease with a broad temperature tolerance to prevent grease run-off or hardening in extreme heat or cold.
NLGI grade and additives: Common NLGI #2 greases offer versatile performance. Look for corrosion inhibitors, rust protection, and compatibility with metal bearings used on trailers and lifts.
Volatility and maintenance interval: Higher oxidation resistance translates to longer service life and fewer re-lubrication cycles, reducing maintenance downtime and labor.
Brand and availability: Reputable marine brands provide formulations tested for marine use. Consider availability in your region and whether you prefer single-tube purchases or bulk options for frequent lubrication.
Application and tooling: Some products are designed for use with grease guns, while others come in cartridges or tubes. Ensure your lubrication method aligns with the product packaging.
Environmental considerations: If you handle watercraft near sensitive ecosystems, select a grease with minimal leaching and low solubility in water to limit environmental impact.
