The Buckshot Racing #77 next-generation F1 / Drag Forged Race Piston Kits (Single Ring) are precision-engineered for Mercury Racing 2.5 Liter Outboards, specifically designed to enhance the performance of high-output models such as the 260 HP, 280 ROS, 300 Drag, F1, and S3000 race motors.
 
These complete piston kits serve as direct replacements for OEM pistons, rings, wrist pins, and circlips, offering advanced features tailored for competitive racing environments.​
 
Each kit includes forged, top-pinned pistons that are angle-cut, lightened, balanced, and coated to minimize friction and wear. The inclusion of lightened wrist pins and single gold rings further reduces reciprocating mass, contributing to improved engine responsiveness.
 
The pistons are compatible with standard Nikasil-plated cylinders and feature top locator pins to ensure precise ring positioning, enhancing combustion efficiency.​
 
The comprehensive kit is priced at $1,995 and comprises six full sets, each containing pistons, rings, wrist pins, and circlips.
 
This pricing offers a significant cost advantage compared to current Mercury OEM market prices, which are listed at $2,895. For engines equipped with steel sleeves, chrome-faced dual rings are available as an alternative.
 
Both gold and chrome single-ring options are offered to accommodate various performance requirements. Additionally, Buckshot Racing provides Nikasil and steel sleeves to match different cylinder configurations.​
 
These piston kits are compatible with and can replace several Mercury Racing OEM part numbers, including 848200A12, 840663A12, 848201A12, 827352-8, 827353T20, 827353T9, 827352-6, 827353-6, 827352-8, 8273538, 827352T20, 2717-827352-8, 827352T9, 827352A13, and 827353A13.
 
This compatibility ensures seamless integration into existing engine assemblies, providing racers and performance enthusiasts with a reliable and high-quality piston solution.
