YAMAHA Yamalube 2M Outboard 2-Stroke Oil 1 Gallon — NMMA TC-W3, Semi-Synthetic Protection

Yamalube 2M Outboard TC-W3 is a semi-synthetic 2-stroke oil formulated to protect and optimize outboard marine engines in corrosive, high-demand water environments.

Designed by Yamaha for use in 2-stroke outboard motors, this 1-gallon Yamalube 2M delivers NMMA TC-W3-approved lubrication with additives that fight ring stick, carbon deposits, wear, and corrosion. The formula balances synthetic and mineral components to provide reliable protection under variable loads and saltwater exposure while supporting consistent engine performance.

How does this oil help engines perform on long marine runs?

Yamalube 2M helps maintain engine efficiency on extended trips by minimizing deposits that reduce power and by reducing friction between moving parts. Its semi-synthetic composition sustains stable lubrication at different temperatures, so the engine breathes and revs more predictably during long runs.

• NMMA TC-W3 approval for broad outboard compatibility.
• Additives that reduce ring stick and carbon buildup.
• Improved shear stability for sustained lubrication under load.

Will this oil protect my outboard from corrosion and wear?

The formula includes targeted anti-wear and anti-corrosion agents to shield crucial internal parts from moisture and salt exposure common in marine settings. By lowering metal-to-metal contact, it helps extend component life without affecting normal engine operation.

• Anti-corrosion additives guard bearings, crankcases, and liners.
• Wear inhibitors reduce friction on rings, pistons, and gears.
• Protective chemistry suited for saltwater and freshwater use.

Is this oil right for my vessel and engine type?

This product is intended specifically for 2-stroke outboard engines and meets the NMMA TC-W3 specification that many manufacturers require. It is not recommended for land-based engines, personal watercraft like WaveRunners, or sport boats that use different oil formulations or direct-injection systems.

• Perfect for 2-stroke outboards requiring TC-W3 approval.
• Not formulated for WaveRunners, sport boats, or onshore engines.
• Sold in 1-gallon size for convenient service intervals.

How should I use and store this 1-gallon container?

Follow your engine maker's oil-to-fuel ratio and mixing or injection instructions. Store the sealed gallon in a cool, dry place away from direct sunlight and extreme temperature swings to preserve additive effectiveness and shelf life.

• Observe the OEM-recommended mix ratio or injection requirements.
• Keep container tightly closed when not in use to prevent contamination.
• Store upright in a ventilated area, away from heat sources.

Who is this for: Yamalube 2M Outboard TC-W3 1-gallon is aimed at boat owners, professional mariners, and fleet operators who run 2-stroke outboard engines and need a dependable, NMMA-approved semi-synthetic oil to limit deposits, reduce wear, and resist corrosion in marine environments. If you operate a 2-stroke outboard and want a manufacturer-backed lubricant tuned for saltwater and freshwater use, this product is a practical choice; if you run personal watercraft, sport boats, or land engines, consult your engine manual for the correct oil type.
