Buckshot Racing #77 stainless race cowl torsion clip replacing discontinued Mercury 848126A1 and 99779 for compatible Pro Max 150, 200, 225 HP, SST-120, S2000, S3000, 2.4L EFI, Bridgeport, ModVP, and 2.5L Mercury Racing cowls.
The Buckshot Racing #77 Mercury Race Cowl Torsion Clip is a marine-grade stainless replacement for discontinued Mercury OEM 848126A1 and the earlier Mercury 99779 Offshore cowl clip. This small spring-style component is an important part of the lightweight cowl-support systems used on many classic Mercury Marine and Mercury Racing 2.0L, 2.4L and 2.5L V6 two-stroke outboards.
The 848126A1 torsion clip works with the cowl support, locating pin and retaining hardware to maintain lateral spring tension on the cowling. This helps control side-to-side movement while keeping the cowl properly indexed against its mounting points.
Reducing unnecessary movement helps minimize vibration, rattling and wear around the cowl supports, locating pins and retaining hardware.
Why the 848126A1 Clip Matters
Mercury Racing lightweight cowls operate in a demanding environment. High RPM, rapid acceleration, tunnel-boat operation, aerodynamic loading, offshore chop and repeated rough-water impacts continually transmit movement through the cowling.
A missing, weakened or distorted Mercury 848126A1 torsion clip can allow increased lateral cowl movement and additional stress on the support pin, retaining cable and surrounding hardware.
The Buckshot Racing #77 replacement restores the spring tension originally designed into the Mercury race-cowl system while retaining the factory-style quick-release function.
Mercury Racing 2.0L Applications
The 848126A1 Torsion Clip Assembly is used with lightweight competition cowls found on classic Mercury Racing engines such as the SST-120 and S2000. These approximately 2.0L, 122-cubic-inch V6 race outboards operate at sustained high RPM in tunnel-boat and Formula competition where secure cowl support is especially important.
This style of race cowl is also familiar in Formula One, F1H2O, US F1 and Australian Formula racing. Because cowls and powerheads are frequently swapped between race engines, fitment should be confirmed by the actual cowl-support arrangement rather than decals or horsepower alone.
Mercury Racing 2.5L Applications
The same Mercury 848126A1 torsion clip is used on compatible 2.5L Mercury Racing lightweight cowls, including the S3000, 2.5L Carb, EFI and EFI Offshore configurations.
Common engines associated with this style of cowl include the 245 HP Carb, 260 EFI, 150 Pro Max, 200 Pro Max and 225 Pro Max, along with other Mercury Racing and high-performance 2.5L V6 combinations using the same cowl-support system.
The determining factor is the 848126A1 / 99779-style torsion clip and support-pin configuration, not engine horsepower alone.
Earlier Mercury 99779 2.4L Offshore Clip
The earlier Mercury 99779 cowl clip was used on previous-generation performance and offshore cowl systems, including classic 2.4L EFI, XR2/Magnum and other early Mercury high-performance V6 applications.
Mercury parts information identifies 99779 as an Offshore cowl clip, with 848126A1 becoming the later replacement-style torsion clip. The Buckshot Racing #77 replacement is therefore useful for restoring both later 848126A1 and earlier 99779-style Mercury race cowls.
Marine-Grade Stainless Construction
The Buckshot Racing #77 848126A1 replacement torsion clip is manufactured from marine-grade stainless steel for spring strength and corrosion resistance in freshwater and saltwater environments.
This area is regularly exposed to moisture, spray and condensation. Corrosion can weaken the original clip or reduce its ability to maintain proper tension. Stainless construction provides a durable replacement for racing, performance and offshore applications.
Installation retains the simple Mercury-style design: insert the torsion-clip pin through the corresponding cowl support pin and close the retaining ring. This allows quick cowl removal while keeping the cowling securely retained during operation.
Buckshot Racing #77 Tech Tip
When replacing a Mercury 848126A1 or 99779 torsion clip, inspect the entire cowl-retaining system. Check the support pin, retaining cable, brackets, mounting holes, and attachment hardware for looseness, cracking, or wear.
After installation, verify that the clip provides positive spring tension and that the cowl sits correctly on its locating points without binding.
Replacing a Discontinued Mercury Racing Part
With original Mercury OEM 848126A1 Torsion Clip Assemblies increasingly difficult to find, the Buckshot Racing #77 stainless replacement provides a practical service solution for preserving original Mercury lightweight race-cowl systems.
For compatible Mercury Racing SST-120, S2000, S3000, 2.4L EFI, 245 Carb, 260 EFI, Pro Max, EFI Offshore and other 2.0L, 2.4L and 2.5L V6 race-cowl applications, the 848126A1 / 99779 torsion clip restores the lateral support needed to keep the cowling stable and properly positioned during high-RPM and rough-water operation.
