The 100-piece 8-inch Radial Hose Zip Ties Kit from Buckshot Racing #77 are heavy-duty marine cable ties designed as a direct replacement for Mercury 54-816311T / 816311 in compatible hose- and wire-retention applications.
Built for demanding marine service, each tie is made from UV-resistant, non-corrosive nylon and is rated at 50 lb tensile strength. The 8-inch length and radial locking profile make it well suited for securing fuel lines, water hoses, bleed hoses, control lines, and electrical wire bundles throughout Mercury, Mariner, Force, and SportJet applications.
Unlike a basic hardware-store cable tie, this radial hose tie uses a rounded head and curved locking profile that wraps more evenly around the hose or harness. That helps reduce concentrated pressure points while maintaining a firm grip in areas exposed to vibration, heat cycling, and moisture.
50 lb Tensile Strength for Marine Service
Each tie is rated at 50 pounds of tensile strength, giving it significantly more holding capacity than many light-duty household cable ties.
That strength rating is especially useful in under-cowl applications where hoses and wire bundles are constantly exposed to engine vibration and movement. The added holding strength helps keep routing stable and prevents hoses or wiring from shifting against brackets, engine castings, or other components.
Designed for Fuel Lines, Water Hoses & Wiring
The 816311-style tie is commonly used throughout Mercury applications for securing fuel hoses, cooling-water hoses, siphon hoses, bleed lines, and electrical harnesses.
The Buckshot Racing #77 replacement is designed for the same type of service and is particularly useful during fuel-system rebuilds, water-hose replacement, ignition service, powerhead assembly, and complete engine restorations.
The radial profile helps the tie sit more naturally around soft hose compared with a standard square-head cable tie, making it a better choice for marine engine work.
Built for High-Performance & Racing Applications
High-performance outboards put extra demands on under-cowl hardware because they run at higher RPMs and vibration levels.
For Mercury Racing, offshore, drag-race, tunnel-boat, lake-race, and endurance applications, secure hose and wiring management is essential. A loose fuel line, water hose, or ignition lead can quickly become damaged by abrasion or contact with moving and hot components.
These ties provide a clean, durable way to maintain organized routing without adding bulky clamps in locations where a tie strap is the proper retention method.
Broad Mercury, Mariner, Force & SportJet Use
The 816311 / 816311T-style tie is used across a wide range of Mercury-family engines. It can be found on many Mercury and Mariner two-strokes, Optimax DFI engines, SportJet systems and selected Force outboards, depending on the hose or wiring assembly.
Because the same tie can appear on many different engine families, fitment is best confirmed by the original part number or by comparing the size and style of the existing tie.
Common Cross-Reference Numbers
Common part-number references include 54-816311T, 816311T, and 816311.
Additional interchange numbers may include 21465, 369843980M, 5030347, 5035626 and 5040220.
Buckshot Racing #77 Tech Tip
Do not reuse old nylon ties during a major engine service. Heat, fuel vapor, UV exposure, and age can make old ties brittle even when they still look acceptable. Replacing them during routine service is inexpensive and helps eliminate another potential failure point.
Route hoses naturally without kinking them, tighten the tie firmly without crushing the hose, and trim the tail cleanly so no sharp edge is left near wiring, fuel lines, or service areas.
The Buckshot Racing #77 8-inch Radial Hose Tie offers a stronger, cleaner, more professional replacement for aging Mercury 816311T-style ties in fuel, cooling, and electrical applications.
Specifications: 8-inch length, 50 lb tensile strength, UV-resistant marine nylon, rounded radial locking design, black finish, and 100 ties per package. Compare to Mercury at $60 MSRP per 100.
