Quicksilver Marine Grease Gun with 3 oz Cartridge 74057Q5 — PTFE Lithium NLGI 2, Corrosion-Resistant

Quicksilver 74057Q5 is a PTFE‑enhanced, lithium‑based NLGI 2 marine grease supplied in a 3 oz cartridge and paired with a dispensing gun for precise application on boats and marine equipment.

Built to meet Mercury Marine’s specifications, this compact grease cartridge and gun combo delivers a corrosion‑resistant lubricant formulated to survive wet environments and heavy loads. The 2-4-C formula blends PTFE for reduced friction with extreme pressure additives, making it a go‑to option for steering cables, tilt mechanisms, prop shaft fittings and trailer bearings. Packaged in a convenient 3 oz tube and including a hand gun for accurate placement, the 74057Q5 is sized for routine maintenance and spot repairs.

What makes this marine grease suitable for saltwater and wet conditions?

The grease is a lithium‑based NLGI 2 formula that resists washout and won’t break down when exposed to water. PTFE (Teflon) lowers friction, while anti‑corrosion properties protect metal parts from pitting and rust. This combination helps maintain moving components even after repeated exposure to splashes, spray and humid storage.

• Water‑resistant lithium thickener prevents grease separation
• PTFE reduces wear on sliding and rolling surfaces
• Corrosion inhibitors shield metal against salt and moisture

Which components on my boat or trailer should I use the 74057Q5 on?

This grease is formulated for general marine and trailer maintenance wherever a multipurpose NLGI 2 is appropriate. Typical uses include steering cables, throttle and shift cables, tilt locks and swivel pins, as well as trailer wheel bearings and propeller shaft fittings. It’s intended for points that require a resilient, non‑migrating lubricant under load.

• Steering and control cables for smoother operation
• Tilt mechanisms and tilt tubes to protect pivot points
• Trailer bearings and swivel pins for reduced wear and heat

How does the included grease gun improve maintenance tasks?

The supplied hand gun accepts the 3 oz cartridge for targeted dispensing without messy handling or over‑application. A small, controlled output lets you reach tight fittings and sealed points while minimizing waste. For quick field servicing or scheduled upkeep, the gun plus cartridge format speeds jobs and keeps grease clean until use.

• Compact gun fits small spaces for precise application
• Cartridge system reduces contamination and waste
• Easy single‑hand operation for quicker on‑boat servicing

Will this grease handle heavy loads and high pressure points?

Yes—the formula contains extreme pressure (EP) additives designed to protect metal surfaces under significant friction and load. While it’s intended as a general‑purpose marine lubricant, the EP package helps prevent metal‑to‑metal contact in pins, shafts and bearings. It’s suitable for many heavy‑duty marine applications, though specialized gear oils or high‑temperature greases may be better for extreme conditions.

• EP additives reduce wear in high‑pressure contacts
• Maintains consistency across a wide temperature range
• Good for both rolling and sliding load points

Who is this for: Boaters, marina technicians and trailer owners who need a reliable, easy‑to‑use marine grease for routine maintenance. If you service Mercury Marine equipment or want a compact cartridge and gun setup for targeted lubrication of steering controls, tilt mechanisms, prop shafts and trailer bearings, the Quicksilver 74057Q5 offers specification‑grade protection in a user‑friendly package. It’s also practical for weekend DIYers who prefer clean, precise application during seasonal checks and repairs.
