The Two-Stroke Water-Cooled Outboard Additive Package is a high-performance blend of ashless additives, rust inhibitors, and detergents, designed to deliver exceptional lubricity, abrasion resistance, and smoke reduction. It meets the stringent performance requirements of NMMA TC-W3, ensuring optimal performance for two-stroke water-cooled outboard engines.

These engines operate under unique conditions compared to four-stroke engines, requiring a specialized mix of additives to achieve superior performance, protection, and durability. This additive package is tailored to address these specific needs.

Key Functions of the Additive Package:

• Detergent Action: Prevents deposit formation on key engine components like pistons, rings, and combustion chambers, ensuring consistent power output and smooth operation.
• Lubrication: Offers effective lubrication to reduce friction and wear between moving parts, helping to extend engine life.
• Corrosion Protection: Guards internal engine components from rust and corrosion, particularly in challenging marine environments.
• Smoke Reduction: Minimizes exhaust smoke and emissions, improving environmental performance and ensuring compliance with regulatory standards.
• Fuel Stabilization: Prevents fuel degradation and oxidation, ensuring stable engine performance and easy starting.

Components of the Additive Package:

• Detergents: (e.g., Calcium sulfonates, magnesium sulfonates) – Clean engine components by neutralizing acids and dispersing sludge.
• Dispersants: (e.g., Polyisobutylene succinimides) – Suspend particles in oil to prevent sludge and varnish formation.
• Anti-Wear Agents: (e.g., Zinc dialkyldithiophosphates, ZDDP) – Form protective films on metal surfaces to reduce wear.
• Corrosion Inhibitors: (e.g., Amine-based inhibitors, calcium sulfonate) – Prevent rust and corrosion by forming a protective barrier.
• Smoke Suppressants: (e.g., Polyisobutylene, PIB) – Reduce visible exhaust smoke.
• Fuel Stabilizers: (e.g., Antioxidants like hindered phenols) – Prevent oxidation and maintain fuel stability.
• Emulsifiers: (e.g., Nonionic surfactants) – Ensure even mixing of oil with fuel for consistent lubrication.
• Solvents: (e.g., Mineral oils, synthetic base oils) – Assist in the dispersion and proper mixing of additives in the fuel.

Application and Benefits:

• Enhanced Engine Performance: Clean and well-lubricated components ensure smoother operation, improved power output, and better fuel efficiency.
• Extended Engine Life: Reduced wear and corrosion offer long-term protection, cutting down on maintenance costs.
• Improved Environmental Compliance: Lower smoke emissions and reduced exhaust visibility help meet environmental regulations and minimize the environmental impact.
• Reliability in Marine Environments: Formulated to perform in harsh marine conditions, including saltwater exposure and fluctuating temperatures.

The Two-Stroke Water-Cooled Outboard Additive Package is an essential component for optimizing the performance, extending the life, and ensuring the environmental compliance of outboard engines. Its comprehensive formulation of detergents, dispersants, anti-wear agents, corrosion inhibitors, and other components offers a reliable solution for maintaining engine efficiency and reducing long-term maintenance costs. Regular use of this additive package is critical to achieving peak performance and maximizing the lifespan of two-stroke water-cooled outboard engines.
