BLUE MARINE FAT 400gr

Function and technical context

Blue marine grease is a lubricant specifically formulated for nautical environments, where constant exposure to salt water, humidity and temperature variations require superior protection than any conventional grease. Its field of application covers tail shaft bearings, rudder ball joints, propeller bushings, steering joints, tail gears and all those lubrication points that work submerged or in frequent contact with the marine environment. This grease acts as a barrier against galvanic corrosion and water ingress, keeping metal surfaces lubricated and protected throughout the boating season. Poor lubrication in these components can lead to premature wear of the bushings, seizure of joints, accelerated corrosion and, in the most serious cases, loss of maneuverability or structural damage to the propulsion system.

When to replace or reapply this grease?

The most common symptoms that indicate that the grease points need attention are: squeaking or resistance in the steering, unusual vibration in the tail shaft, difficulty moving the rudder, or excessive play in the steering ball joints. It is recommended to check and reapply marine grease at all greasing points at the beginning of each boating season and after any prolonged stranding, as exposure to salt water degrades the lubricating film over time. Preventatively applying grease at every seasonal maintenance is the most effective practice for avoiding costly breakdowns at sea and prolonging the life of propulsion and steering components.
