At Buckshot Racing #77, we offer a selection of quick-connect fittings to upgrade the water outlet systems on Mercury Marine and Mercury Racing 2.0L, 2.4L, and 2.5L outboard engines.
 
These fittings are ready-to-install components trusted across marine, automotive, and industrial sectors for their performance, and reliability. The NPT threads are directly compatible with both OEM Mercury thermostat housings and our precision-machined #77 Billet Water Outlets.
 
90-Degree Elbow Quick-Connect Fittings
 
Our elbow quick-connect fittings feature a 1/2-inch outer diameter (OD) tube connection and a 1/4-inch NPT male thread, providing a compact, 90-degree routing solution for cooling systems. Constructed from durable plastic and copper materials, these fittings are rated for working pressures from 0 to 145 PSI, making them ideal for marine cooling applications exposed to harsh elements.
 
These elbow fittings are not only widely used in the marine industry but also serve in automotive, medical, and aerospace environments—supporting applications like air suspension systems, pneumatic controls, and cooling lines where quick serviceability and leak resistance are vital.
 
Compatible with popular OEM Mercury part numbers such as 75692, 75692Q2, and 75692T3, these fittings integrate seamlessly with your outboard's existing hardware. Whether you're replacing worn factory elbows or outfitting a high-performance racing setup, this fitting delivers a clean, professional solution that installs in seconds.
 
Tee Push-to-Connect Fittings
 
Our Tee-style quick-connect fittings are built from robust PBT plastic and feature three 1/2-inch OD push ports in a classic “T” configuration.
 
These fittings are ideal for branching water lines—perfect for dual water outlets, bypass circuits, or flow splitting. With a zinc alloy ferrule and an ergonomic POM elliptical quick-release button, these fittings allow 360° tube rotation and simple, tool-free disconnection for hassle-free maintenance or configuration changes.
 
Just like our elbow fittings, these tees are rated for 0 to 145 PSI, ensuring consistent performance under pressure. They're widely used in both low-pressure hydraulic systems and pneumatic applications across the automotive and medical equipment industries, offering a flexible and dependable solution wherever precise fluid control is needed.
 
These fittings are directly compatible with Mercury OEM part numbers such as 62386, 90390A1, 687271, 68728, 475331, 47533, and 90390. They are a smart choice for installers looking to maintain OEM reliability while improving the modularity and accessibility of their water systems.
 
Pair with Buckshot Racing #77 Translucent Red or Blue Hose
 
For the cleanest and most efficient installation, we recommend pairing both the elbow and tee fittings with our Buckshot Racing #77 translucent red water outlet hose. This hose is specifically selected for its flexibility, high visibility, and durability under marine operating conditions, making it easy for visual inspection flow, detect issues early, and keep your setup looking sharp.
 
Whether you're upgrading a Mercury outboard for racing, customizing a cooling system, or replacing OEM components, these quick-connect fittings offer the right blend of performance, convenience, and broad industry compatibility. Trusted across marine, automotive, aircraft, and medical applications, they deliver plug-and-play simplicity with pro-grade results.
