The tilt tube in an outboard motor is a critical component that facilitates the engine’s tilt and trim functions, allowing the motor to pivot smoothly. This hollow tube connects the outboard engine to the transom of the boat, ensuring a reliable steering mechanism and reducing unwanted vibrations.
 
Over time, stock tilt tubes tend to corrode internally, making it difficult for steering rods to function properly. Additionally, excessive wear on these tubes can lead to unwanted movement in the midsection, adversely affecting handling and overall performance.
 
For owners of Mercury Marine and Mercury Racing High-Performance Single Ram Trim Transom Bracket assemblies, an upgraded stainless steel tilt tube provides a durable, corrosion-resistant alternative.
 
The Custom Stainless Tilt Tube from Buckshot Racing #77 is a high-quality replacement that addresses these issues, offering improved longevity and resistance to wear.
 
This custom stainless steel tilt tube is designed to fit a wide range of Mercury Marine and Mariner outboard engines, including 2.0L, 2.4L, 2.5L, and 3.0L V6 models. It is also compatible with inline 3-cylinder and 4-cylinder Mercury outboard motors, ensuring broad applicability across different power ranges.
 
This replacement upgrade is ideal for high-performance Mercury models such as the V-175XRI, V-200, Pro Max, 300X, 200 HP 6-CYL,  6-CYL, and 225 EFI Pro Max, as well as mid-range models like the 80 JET, 100 HP (4 CYL), 115 HP EFI, 75 HP EFI, and 90 HP Carb.
 
By replacing a corroded or worn-out tilt tube with a stainless steel alternative, boaters can restore smooth steering, reduce midsection instability, and enhance the overall handling performance of their outboard motor.
 
These engines, especially high-performance models like the 260 EFI, 280 ROS, 300 Drag, 300X, 300XS, 225 Pro Max and 200 EFI Super Magnum, demand robust and precise steering mechanisms to handle extreme conditions.
 
The stainless steel tilt tube prevents excessive play in the midsection and ensures optimal alignment of the steering system, which is essential for high-speed operation and maneuverability.
 
Compared to the OEM826125 tilt tubes, which are more susceptible to internal corrosion and galling, the Buckshot Racing #77 upgrade offers superior strength and durability. The 1.035 OD stainless steel tube ensures proper fitment across a wide range of single-ram trim transom brackets.
 
For high performance boatlooking to replace their Mercury or Mariner tilt tube, the following OEM part numbers indicate compatibility: 826125A1, 826125A2, 85366, 99170A1, and 99170A2.
 
Ensuring the proper part fitment helps maintain smooth steering, optimal trim operation, and reduces midsection instability in outboard motors ranging from 75 HP EFI to 300 HP EFI Pro Max configurations.
 
Add Two (2) Thin Jam Nylon Insert Lock Nuts (NTE), one for the big end and one for the small end. Our nuts are hardened steel zinc-plated, making them corrosion-resistant and rarely prone to gall when compared to stainless on stainless.
