Yoursme Marine Steering Tube Grease Nut 7/8" Thread — Anodized Black, OMC 2861 Fit, Double O-Ring Seal

Yoursme's Marine Steering Tube Grease Nut is a 7/8" threaded replacement designed to seal and lubricate OMC-style outboard hydraulic and cable steering systems.

This compact, aircraft-grade aluminum grease nut fits OMC 2861 / FSM068 applications and other cable or side-mount hydraulic steering setups, providing a clean access point for controlled lubrication. The anodized black, fully hardened body resists corrosion in marine environments while an integrated double-high pressure O-ring helps keep water and contaminants out of the steering tube.

How does this grease nut improve steering system maintenance?

By providing a sealed grease port directly on the exposed steering rod threads, the grease nut allows targeted lubrication of internal components without disassembly. Regular greasing reduces friction and helps prevent buildup that causes stiff or greasy steering rods.

• Enables use of a hand-pumped grease gun for precise greasing.
• Seals with double-high pressure O-ring to limit water intrusion.
• Helps keep rod threads and inner tube clean from contaminants.

Will this part fit my boat’s OMC steering setup?

The grease nut is machined with a 7/8" thread specifically to match OMC 2861 / FSM068 dimensions and similar outboard steering rods. Confirm thread size on your unit before purchase to ensure proper fit.

• Thread: 7/8" standard for compatible OMC rods.
• Designed for cable and side-mount hydraulic steering systems.
• Check exposed threads — three or more threads recommended during installation.

How do I install and use the Yoursme steering tube grease nut?

Installation is straightforward and typically completed with basic hand tools. Wipe the steering rod clean, secure the grease nut on exposed threads, ensure the grease fitting faces outward, then apply grease with a hand pump — avoid over-lubrication.

• Remove tiller rod linkage nut and separate tiller rod.
• Clean the steering rod and fit the grease nut onto exposed threads.
• Use 1 full grease shot, 2 max; reconnect tiller rod afterward.

What are the material and durability benefits of this grease nut?

Constructed from aircraft-grade aluminum with an anodized black finish, the grease nut is hardened for precision and longevity. Its corrosion-resistant surface holds up to marine exposure while the sealed design reduces internal wear on steering components.

• High-grade aluminum for low weight and high strength.
• Anodized finish for corrosion and saltwater resistance.
• Hardened machining for reliable thread engagement and longevity.

Who this product is for: boat owners, mechanics, and marinas that service OMC-style outboard engines or side-mount hydraulic steering systems and want a durable, easy-to-install grease access point. If you maintain cable steering or hydraulic side-mount systems and prefer tidy, controlled lubrication to prolong cable life and reduce messy steering rods, the Yoursme grease nut is a practical upgrade. Confirm your steering rod thread size before ordering. Yoursme supports the product with a 30-day return policy and a 12-month warranty for added peace of mind.
