The Buckshot Racing #77 Billet Race Starter Motor Brackets are engineered for Mercury Outboard Motors enthusiasts who demand strength, precision, and style.
Designed with the performance and durability needs of both racers and serious anglers in mind, these starter brackets are CNC-machined from high-grade 6061 billet aluminum and offer an ideal blend of lightweight performance and structural integrity.
Compatible with Mercury Marine, Mariner, and Mercury Racing 2.0, 2.4, and 2.5 Liter V6 2-stroke engines, these brackets offer a sleek upgrade for a wide range of displacements and horsepower levels.
Each billet bracket mount is meticulously finished with a hard-anodized coating available in Red, Blue, or Black to provide maximum corrosion resistance and an eye-catching appearance. The black anodized option remains the most popular for those looking to maintain the classic Mercury Racing aesthetic, but all finishes are engineered for long-lasting performance in both freshwater and saltwater environments.
This high-performance replacement set eliminates the factory flywheel cover mount point and front-facing oil reservoir mount, making it ideal for stripped-down race configurations or custom fishing builds. Whether you're running a stock Mercury 135 HP Black Max or pushing a high-output 300 HP Drag engine, these brackets deliver enhanced fit and finish for virtually all Mercury Outboard Motors in the 2-stroke V6 lineup.
Our race-proven billet mounts are compatible with multiple factory part numbers, including Mercury 8M0088723 for the upper bracket, 76866 for the lower starter cover, 76867 cover variant, and 42249 engine mount.
These part numbers correspond to a wide array of OEM starter bracket configurations used on Mercury / Mariner outboards ranging from 135 to 300 horsepower, including the XR2, XR4, XR6, XRi, 175 HP, 200 HP, 225 Pro Max, 245 Carb, 260 EFI, 280 ROS, and the legendary 300 Drag engines. Covering production years from 1976 through 2015, these brackets provide broad compatibility and a performance-focused replacement solution.
Included in each complete set are four stainless steel socket head bolts, four matching lock washers, and a classic-style Mercury Racing cowl decal—delivering not just function, but a nod to Mercury's iconic legacy in high-performance marine propulsion. With better-than-OEM quality and enhanced visual appeal, Buckshot Racing's billet brackets offer the ideal upgrade for any serious Mercury outboard build.

7 disciplines we employ on every Billet part!
1. We select and use high-quality cutting tools designed for aluminum machining to minimize tool wear and achieve a smooth finish.
2. We work to optimize speeds and feeds, adjusting cutting speeds and feed rates to achieve the optimal balance between material removal and surface finish.
3. We employ coolant or lubricant to dissipate heat and reduce friction during machining, which helps prevent tool overheating and improves surface finish.
4. We ensure our tool runout is minimized to reduce vibration and chatter, which can negatively impact surface finish.
5. We implement proper tool paths including climb milling, to minimize tool deflection and achieve a better surface finish.
6. We perfect ramping, profiling, or contouring to find the most suitable approach for each part.
7. We properly calibrate and align our CNN machines to achieve accurate cuts, which enhances surface finish. This includes inspecting and maintaining utilized CNC machines and tooling to ensure optimal machining every run.
These Made in the USA practices have helped us enhance the precision and the surface finish of our Buckshot Racing #77 Speed Store CNC machined 6061 aluminum billet parts, to the highest level.
