Pro Super Sport Piston Kits from Buckshot Racing #77 are a premium aftermarket solution tailored for Mercury 3.0 Liter EFI and carbureted 2-stroke outboard engines.
Renowned for their precision and durability, these piston kits are engineered to provide a reliable, high-performance alternative to OEM Mercury Marine parts and components.
Constructed using high-grade aluminum alloys, Pro Piston Kits are specifically designed to meet the rigorous demands of old-school 2-stroke outboards. The high silicon content in the alloy enhances wear resistance and optimizes thermal expansion properties, minimizing the risk of seizing during high-temperature operation.
For long-term durability, these pistons are treated with advanced anti-corrosive coatings, which protect against oxidation and pitting caused by saltwater air exposure getting into the motor. The manufacturing process ensures precision machining for exact dimensional tolerances, enabling seamless integration into Mercury 3.0 Liter outboard engines.
The Piston Kits are designed to maximize the performance of Mercury 3.0 Liter EFI and Carbureted (WMH and WMV Carbs) outboards. Their shape is crafted to match the combustion chambers of these engines, promoting efficient fuel combustion and boosting power output.
The precision-machined ring grooves improve oil control and reduce blow-by, resulting in cleaner combustion and extended engine life.
Despite their robust construction, these pistons are lightweight, reducing reciprocating mass for smoother engine operation and the ability to achieve higher RPMs.
When installed in Mercury 3.0 Liter EFI and carbureted outboards, Pro Piston Kits provide great performance. The high-silicon aluminum alloy construction ensures excellent heat dissipation, preventing the formation of hot spots that could lead to piston failure.
These pistons are capable of handling the high rotational speeds typical of the Mercury 3 liter 2-stroke outboard engines, ensuring reliable performance even under heavy loads. Their resilience to pressure fluctuations reduces the risk of detonation damage, a common concern in high-performance boating applications.
Combined with superior wear resistance and compatibility with cylinder bore materials, these pistons significantly extend the engine's operational life.
Specifically engineered for Mercury 3.0 Liter engines, the Kits from Buckshot Racing #77 are compatible with both EFI and carbureted models.
They are available in a range of sizes and configurations to suit different bore dimensions and compression ratios.
1) Standard (3.625")
2) +15 Over Bore (+0.015")
3) + 30 Over Bore (+0.030")
Each kit includes essential components such as wrist pins, circlips, and piston rings, providing a complete solution for engine rebuilds or upgrades.
Proper installation and maintenance are essential for achieving the full potential of Pro Super Sport Piston Kits from Buckshot Racing #77.
Engine cylinders should be honed to the correct crosshatch pattern for optimal ring seating and oil retention.
The piston rings are gapped to Mercury’s specifications to avoid issues like binding or blow-by but should be checked to your bore sizing. Torque settings for wrist pins and connecting rods should follow factory guidelines, and a controlled break-in period is crucial for allowing the pistons and rings to acclimate to the engine.
