Its polymer-enhanced formula ensures strong adhesion and prevents washout, making it ideal for 4WD vehicles, boat trailers, and marine equipment. Trusted by professionals and rated 4.7 stars, this 14 oz. tub delivers reliable protection in the harshest wet environments. ## Description A blue tacky, aluminum complex grease using a highly refined base oil. It has been formulated with a polymer to provide adhesive, non-blend and water wash-out characteristics. Will resist water under the most severe water conditions. Review: Reliable choice - I recently used the Sta-Lube SL3121 Water-Resistant Marine Grease to repack the wheel bearings on my boat trailer, and overall, I’m quite satisfied. The grease has a thick, tacky consistency and is notably water-resistant, which is crucial for marine applications. After several trips, the bearings continue to perform smoothly without any signs of water intrusion. However, I noticed that the grease is a bit more challenging to clean off compared to others I’ve used, likely due to its water-resistant properties. Despite this minor inconvenience, I believe it’s a reliable choice for protecting trailer bearings in wet conditions. Review: Good product at reasonable price - I got this to lube bearings on a mini bike. It seems to work great. I can also use it on anything that needs grease that might get wet. ## Features - A blue tacky, aluminum complex grease using a highly refined base oil - It has been formulated with a polymer to provide adhesive, non-blend and water wash-out characteristics - Will resist water under the most severe water conditions - Applications: 4WD, boat trailer, marine equipment, and more - Size: 14 oz. tub ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CPJMY8 | | Best Sellers Rank | #34,879 in Automotive ( See Top 100 in Automotive ) #10 in Heavy Duty Vehicle Greases & Lubricants | | Brand | Sta-Lube | | Brand Name | Sta-Lube | | Container Type | Can | | Customer Reviews | 4.7 out of 5 stars 911 Reviews | | Global Trade Identification Number | 30072213312103 | | Included Components | Grease | | Item Form | Paste | | Item Type Name | Marine Boat Trailer And 4 X 4 Wheel Bearing Grease | | Item Weight | 16 ounces | | Liquid Volume | 14 Fluid Ounces | | Manufacturer | Sta-Lube | | Material | Aluminum | | Model Number | SL3121 | | Number of Items | 1 | | Package Information | Can | | Part Number | SL3121 | | Recommended Uses For Product | Water | | Specific Uses For Product | Marine, Freshwater, Saltwater, 4WD, Boat Trailers | | UPC | 072213312102 | | Unit Count | 14.0 Ounce | | Upper Temperature Rating | 469 Degrees Fahrenheit | | Viscosity | 21 sq-mm/s | | Warranty Description | Manufacturer Warranty | ## Product Details - **Brand:** Sta-Lube - **Item Weight:** 1 Pounds - **Liquid Volume:** 14 Fluid Ounces - **Material:** Aluminum - **Package Information:** Can ## Images ![SL3121 Water-Resistant Marine Grease - 14 oz.

I use it on my boat trailer bearings and it holds up great. **Q: Can i use this on swimming pool frame to pervent rust** A: I would think its not the right application to use it for. I like fluid film for something like this. Not sure if it will hold up to chlorine though. I use it under my car as a rust preventer. **Q: Is it non-toxic?** A: No this is not "non-toxic". ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable choice *by J***O on April 5, 2025* I recently used the Sta-Lube SL3121 Water-Resistant Marine Grease to repack the wheel bearings on my boat trailer, and overall, I’m quite satisfied. The grease has a thick, tacky consistency and is notably water-resistant, which is crucial for marine applications. After several trips, the bearings continue to perform smoothly without any signs of water intrusion. However, I noticed that the grease is a bit more challenging to clean off compared to others I’ve used, likely due to its water-resistant properties. Despite this minor inconvenience, I believe it’s a reliable choice for protecting trailer bearings in wet conditions. ### ⭐⭐⭐⭐⭐ Good product at reasonable price *by D***N on September 24, 2025* I got this to lube bearings on a mini bike. It seems to work great. I can also use it on anything that needs grease that might get wet. ### ⭐⭐⭐⭐⭐ Great for Vintage Bicycles *by S***7 on May 11, 2025* I use this for greasing all the bearings (bottom bracket, hubs, headset, pedals etc.) of my vintage touring bicycles. It works very well for this purpose, as the grease seems to resist moisture exposure (rain storms, puddles) better than traditional wheel bearing grease does. The consistency of this grease is slightly different (thicker) than traditional bearing grease. I've noticed no difference in rolling resistance compared to using regular grease.
