When it comes to maintaining peak performance in high-output Mercury outboards, Buckshot Racing #77 offers a superior, cost-effective solution with its high-quality replacement rubber bleeder caps.
 
Specifically engineered to replace Mercury OEM part number 26852, these durable caps are a direct-fit upgrade for a wide range of Mercury, Mariner, Mercury Racing, and Quicksilver 2-stroke V6 outboard engines.
 
Constructed from heat- and fuel-resistant EPDM rubber, each cap is designed to provide a secure, leak-free seal over your vacuum bleed check valves—ensuring consistent engine performance, protecting against air leaks, and preventing lean conditions that can damage internal components.
 
Each kit includes twelve (12) bleeder caps, enough to fully replace all bleed line seals on most V6 2.0L, 2.4L, and 2.5L Mercury outboard engines, making it ideal for rebuilds, restorations, or regular preventative maintenance.
 
Engineered for Reliability and Long-Term Performance
 
Buckshot Racing bleeder caps stand apart from inferior vinyl or hard nylon alternatives. They are made from premium-grade EPDM rubber, a material known for its exceptional resistance to high temperatures, fuel exposure, and harsh marine environments. This ensures a long service life and consistent performance, even in extreme conditions.
 
The flexible yet durable design creates a tight, leak-free seal on vacuum bleed check valves and elbows, eliminating the risk of air intrusion that could compromise fuel-air ratios and combustion efficiency.
 
Installation is quick and hassle-free, saving time during regular maintenance or engine overhauls. By preventing vacuum leaks in the bleed system, these caps help maintain the proper fuel-air mixture, resulting in smoother operation and improved engine efficiency.
 
Over time, this reduces wear caused by improper combustion and helps protect critical engine components, ultimately extending the overall life of your outboard.
 
These caps also ensure reliable engine behavior during acceleration and under heavy loads, supporting consistent power delivery in demanding marine environments. In terms of long-term value, the durability of Buckshot Racing #77 caps means fewer replacements, lower maintenance costs, and a better overall return compared to OEM options.
 
Wide Compatibility Across Mercury V6 2-Stroke Outboards
 
Buckshot Racing #77 bleeder caps are compatible with a wide array of Mercury outboard models. They serve as a direct replacement for Mercury OEM part number 26852 and support engines across both recreational and racing segments. Popular applications include the 240 HP Bridgeport, Mod VP, SST-120, SST-140, 245 Carb, 260 EFI, 280 ROS, S3000, F1, and the legendary 300 Drag Mercury Racing engines.
 
Additional compatible outboard configurations include the 175XR2 Jet Drive (pump) with serial numbers from 0E151580 through 0E433153, the 200 DFI Jet Drive (powerhead) with serial numbers from 0E384500 through 1B321669, and the 240 EFI Jet Drive (powerhead) with serial numbers starting from 0E384500 and up.
 
These caps also fit the V-135, V-150, V-175, and V-200 2.5L outboards across a variety of serial ranges. They are a reliable sealing solution for XR2 and XR4 high-performance models as well as the SportJet series, which includes engines used in jet boats ranging from 175HP to 240HP. The bleeder caps are equally effective in Black Max 2.0L and 2.4L outboards, widely known for their torque and acceleration.
 
Built for Every Marine Environment
 
Whether you're offshore fishing, racing at high speeds, or enjoying casual recreational boating, Buckshot Racing #77 bleeder caps offer dependable performance. For anglers, they ensure engine reliability during long trips or competitive tournaments.
 
For racers, they support peak combustion efficiency and throttle response during intense competition. For everyday boaters, they provide peace of mind with every start and run, helping prevent engine hesitation or surging caused by vacuum leaks.
 
Exceptional Value Compared to OEM
 
Each Buckshot Racing #77 kit includes twelve (12) rubber bleeder caps for just $12.00, translating to only $1.00 per cap. In comparison, the Mercury OEM equivalent (Part #26852) is priced at $45.60 per set—or $3.80 per cap—offering over 70% savings. This makes Buckshot Racing the smart, budget-conscious choice for marine technicians, performance tuners, and DIY enthusiasts alike.
