Upgrade your Mercury V6 2-stroke outboard with a premium Socket Head fastener kit designed specifically for the exhaust divider plate. This 40-piece bolt and washer kit is built for reliability, corrosion resistance, easier service, and a cleaner race-ready appearance, making it an excellent choice for routine maintenance, restorations, and high-performance rebuilds.
Purpose-built for the Mercury exhaust divider plate
This kit is designed to replace and upgrade the fasteners used on the Mercury V6 2-stroke exhaust divider plate. Correct hardware matters in this area because the divider plate is exposed to constant heat cycles, vibration, moisture, and corrosion. Using quality fasteners helps maintain clamp load, improves serviceability, and gives the engine a more refined, professional look.
Premium stainless steel bolts
The kit includes twenty (20) stainless steel socket-head Allen bolts (2 sizes) made from 18-8 stainless steel. These bolts provide excellent corrosion resistance for marine use and are a major upgrade over old factory hardware. The socket-head Allen design also makes installation and removal easier, especially in the tight space around the exhaust divider and adapter plate.
High-quality gold zinc-plated AN washers
This kit also includes twenty (20) specialty-sized AN washers with a 0.030-inch thickness and 0.565-inch outer diameter. These washers are made in the USA and finished in gold zinc plating for corrosion resistance and a clean, race-ready appearance. Beyond looks, they help distribute clamp load more evenly across the mounting surface.
Why this kit is a worthwhile upgrade
Replacing old exhaust divider plate fasteners with stainless bolts and quality AN-style washers improves both durability and serviceability. Corroded factory bolts are often difficult to remove, and worn hardware can make future maintenance more frustrating than it needs to be. This kit helps solve those problems while upgrading the appearance of the powerhead at the same time.
Applications and Mercury model coverage
This kit is designed for the Mercury V6 2-stroke exhaust divider plate and fits a wide range of 2.5L Mercury 2-stroke outboards and related high-performance applications. Common model names and search terms include Race, ROS, EFI, XRi, Carb, XR6, SST-120, S3000, S2000, 135 HP, 150 HP, 175 HP, 200 HP, 225 HP, 245 HP, 260 HP, 280 Offshore, 150 Pro Max, 200 Pro Max, 225 Pro Max, and 300 Drag outboards, as well as SportJet and other jet-drive applications.
Replaces Mercury OEM fasteners, including NLA parts
This kit replaces Mercury and Quicksilver fasteners commonly listed in parts diagrams and rebuild notes, including: 848496, 10-848496, 848497, 881190, 10-881190, 8263561, 10-8263561, and 826356.
It also replaces the matching Mercury OEM washer 847526.
Both Mercury OEM bolt 848496 and Mercury OEM washer 847526 are No Longer Available (NLA) in many OEM supply channels, making this kit an ideal replacement for obsolete factory hardware.
Exhaust divider plate assemblies are commonly associated
This fastener kit is commonly tied to divider plate assemblies and listings such as:
840760T, 840760T01, 815552A1, and 815552T1.
Technical specifications
The bolts are 18-8 stainless steel with a socket-head Allen design. The washers are gold zinc-plated AN-style washers, sized 0.030 inch thick with a 0.565 inch outer diameter, and are made in the USA. The kit is intended specifically for the Mercury V6 2-stroke exhaust divider plate.
Kit contents
Each kit includes twenty (20) stainless steel socket-head Allen bolts and twenty (20) gold zinc-plated AN washers, for a total of 40 pieces.
Note on AN hardware
The term AN stands for Army-Navy, a long-established specification standard originally developed for military and aerospace applications. AN-style fasteners and washers are known for precision sizing, consistency, and reliability, which is why they remain popular in aviation, motorsports, and high-performance marine applications.
