Yamalube

Yamalube marine grease is a high-performance lubricant engineered by Yamaha for all grease fittings on outboard motors. This thick, waterproof grease protects moving parts from wear, vibration, and corrosion in both saltwater and freshwater. Ideal for prop shaft splines, steering linkages, cables, and bushings, Yamalube grease extends component life and keeps steering and drive systems running smoothly.

• Highly water-resistant – won’t dissolve or wash out even when submerged in saltwater
• Anti-corrosion formula – shields metal surfaces against rust and oxidation, even in harsh marine environments
• Lithium-Calcium base – combines the benefits of lithium and calcium thickeners for excellent mechanical stability
• Will not break down under high heat or pressure – maintains consistency in extreme conditions
• Compatible with most other greases – can be mixed if necessary without issues

High-quality GL4 (SAE 90) gear oil specifically developed by Yamaha for outboard engine gearcases. It provides outstanding wear and corrosion protection, even in harsh saltwater and high-humidity conditions. An ideal choice for small to mid-size outboard motors that require a GL-4 specification gear lubricant.

• API GL-4 rating – safe for gearboxes with yellow metal (brass/bronze) components.
• Premium mineral base with stable viscosity – ensures reliable lubrication across a wide temperature range.
• Excellent corrosion and rust protection – shields gears in marine environments (saltwater, high humidity).
• Low-foaming formula – maintains effective lubrication and cooling inside the lower unit.

Premium Yamalube GL5 (SAE 90) gear oil designed to withstand extreme pressures in the gearcases of the most powerful outboard engines and sterndrive systems. Developed and approved by Yamaha for V6/V8 outboards (including the flagship V8 F350) and other applications requiring GL-5 specification. It features enhanced extreme-pressure additives for high load protection, superior corrosion resistance, and stability under high temperatures.

• GL-5 heavy-duty formula – provides exceptional oil film strength under extreme pressure and shock loads between gears.
• High-power protection – specifically engineered for large outboards (V6, V8) and sterndrive gearcases where standard GL-4 oils are insufficient.
• Strong anti-corrosion properties – shields the lower unit’s internals from rust and corrosion, even with prolonged saltwater exposure.
• Excellent thermal and oxidative stability – resists breakdown at elevated temperatures, prevents deposit formation around seals, and retains viscosity for reliable lubrication.

Yamalube 10W-40 is a genuine Yamaha 4-stroke engine oil engineered for optimal performance in Yamaha outboard motors and personal watercraft. This latest-generation synthetic oil exceeds API SJ and NMMA FC-W standards, providing superior protection against corrosion, wear, and deposits in the harsh marine environment.

• Specifically developed and tested by Yamaha for 4-stroke outboard engines and WaveRunner personal watercraft, ensuring perfect compatibility and performance.
• Synthetic API SJ formula with strong anti-wear additives extends engine life even at high RPM and heavy loads.
• Excellent oxidation stability – the oil protects parts from varnish and sludge formation, keeping the engine clean and maintaining full power output.
• Ensures easy cold starts and stable oil pressure even during prolonged idling/trolling at low speeds or frequent load changes.
• NMMA FC-W certified marine oil – a guarantee of reliable anti-corrosion protection in saltwater and compliance with all modern manufacturer requirements.
