Outboard engines lack air filters due to their on-water marine design, making them particularly susceptible to contaminants during motor rebuilds, storage, or transport. This is especially true for legacy 2-stroke outboards, which often accumulate dirt and grime from fuel and oil residue under the cowl and in the airbox.
These contaminants can migrate into the carburetor, infiltrating critical components such as fuel passages, reeds, bearings, pistons, cylinders, and cranks, leading to premature wear and engine damage.
The Buckshot Racing #77 Center Pull Tab Carb Caps are engineered to address these vulnerabilities, offering essential protection for all Mercury WH, WMH, and WMV series carburetors, which are found on all 2.0, 2.4, 2.5, and 3.0-liter V6 2-stroke outboards produced from 1976 to 2005 present.
Made from durable red high-density polyethylene (HDPE), these carb caps resist impacts, UV exposure, fuels, and oils, ensuring long-lasting performance in harsh conditions.
Their tapered design provides a tight seal, preventing debris and contaminants from entering the carburetor during storage or transport. The center pull tab is molded for easy, tool-free removal, protecting the carburetor opening from unnecessary debris.
The Buckshot Racing #77 Red Center-Pull Tab Carb Caps are a helpful accessory for protecting legacy Mercury WH, WMH, and WMV model carburetors and ensuring the longevity of legacy V6 2-stroke outboards during rebuilds, storage, and transport.
They combat the effects of grime and debris under the cowl and airbox, reducing maintenance requirements and extending the life of your Mercury 135 HP, 150 HP, 175 HP, 200 HP, 225 HP, 250 HP, XR2, XR4, XR6, SST-120, SST-140, and old school Black Max carb outboards.
These caps fit under the stock sound attenuator plate, in the stock carb barrels, billet carb stacks, and setups with Mercury SST-120 and SST-140 plates. This includes all larger and smaller bore venturi variations.
Each set includes six (6) red center pull carb caps, buy three (3) sets (18 total) and save $15 for complete protection for multi-powerhead carb setups. These caps help preserve carburetor cleanliness, prevent clogs and wear, and maintain optimal engine performance.
