Troubleshooting & FAQ

How do I know if this anchor pin fits my sterndrive?

This pin is specifically designed for all MerCruiser Bravo models, including Bravo I, II, III, X, XR, and XZ. To ensure a perfect match, always compare the part numbers (e.g., 17-44166, 18-2461) and dimensions listed on this page against your existing part before ordering.

What are the signs of a failing rear anchor pin?

Common signs of a worn or failing pin include excessive play or "slop" in the sterndrive when trimmed up, clunking sounds during trim operation, or visible corrosion, pitting, and wear on the pin and bushings.

Is this a difficult part to replace?

This task is moderately difficult as it requires securely supporting the full weight of the sterndrive. If you lack the proper equipment or are not comfortable with the procedure, professional installation is highly recommended for safety and to prevent damage.

How often should the anchor pin be inspected or replaced?

It is good practice to inspect the anchor pin and its related hardware (bushings, nuts) annually for any signs of wear, looseness, or corrosion. Replace it immediately if any issues are found to avoid stress on the transom and trim assemblies.
