The Buckshot Racing #77 Race Cowl Support Bracket is a precision-engineered, high-performance upgrade for Mercury Racing 2-stroke V6 outboards.
 
CNC-cut from aerospace-grade 6061-T6 billet aluminum, this lightweight bracket delivers exceptional strength, corrosion resistance, and durability—making it ideal for competitive and high-output marine applications.
 
Designed as a direct replacement for multiple Mercury Racing OEM part numbers—including 71852, 74758, 8218791, 8218771, 821877-A2, 821878, and 821880-A3—this bracket offers drop-in fitment with no modifications required.
 
It’s compatible with a wide range of Mercury 2.5L racing outboards, including the SST-120, S2000, F1, Champ, 260 EFI, 245 Carb, 2.5 Liter ROS (Race Offshore), S3000, Pro Max, 300 Drag, and like-kind powerhead models.
 
The stainless steel OEM racing cowl brackets are no longer available (NLA), so we decided to CNC-machine the part from solid billet aluminum for consistent strength and reliability.
 
Its lighter weight reduces upper cowl movement and helps prevent the risk of damaging or losing your valuable race cowl—especially in high-speed, high-vibration environments like tunnel hull racing, drag racing, and offshore competitions.
 
The 6061-T6 aluminum construction is glass-beaded before anodizing for an improved finish and enhanced fatigue resistance, making it highly suitable for both freshwater and saltwater use.
 
This bracket is a go-to solution for racers, marine technicians, and outboard enthusiasts looking for reliable Mercury outboard upgrades, billet racing parts, or performance support brackets.
 
It maintains factory mounting geometry for easy installation while offering a true performance upgrade over discontinued or failure-prone OEM components.
 
Whether you’re prepping a vintage 280 EFI for the next race or replacing a worn cowl mount on a 300 Drag, the Buckshot Racing #77 delivers the race-proven performance you can trust.
 
This kit is designed for top racers and performance enthusiasts who demand top-tier reliability, reduced weight, and improved performance.
 
Includes one (1) Buckshot Racing #77 Race Cowl Support Bracket (as pictured) with a glass-bead finish before anodizing, available in red, blue, or black, for enhanced durability, corrosion resistance, and a clean, professional look.
 
Installation: Ensure you have the needed supplement parts, adjust the bracket pin height to best fit your cowl setup, and tighten the sandwich nuts with a touch of Red 271 Thread-Locker or equivalent.
