Installation Notes

Ensure the engine is off and the stern drive is in a safe, accessible position. Using a trim support is recommended.
Remove the existing trim cylinder pin that secures the cylinder to the gimbal housing.
Carefully press or knock out the old, worn bushing from the trim cylinder eye.
Clean the bushing housing to remove any debris or corrosion.
Align the new bushing and use a suitable press or socket to gently press it into place until it is fully seated.
Re-install the trim cylinder pin and secure any retainers.
Test the power trim system to ensure smooth and correct operation.

Troubleshooting & FAQ

What is this bushing's function on a MerCruiser Bravo drive?

This bushing is installed in the eye of the power trim cylinders. It provides a smooth, low-friction pivot point for the pin that connects the trim cylinder to the transom assembly, allowing the stern drive to be tilted up and down.

How can I tell if my trim cylinder bushings need to be replaced?

Signs of worn bushings include excessive play or "slop" in the trim system, jerky or uneven trim movement, and audible clunking or grinding noises when trimming the drive up or down. A visual inspection may also reveal a visibly elongated or deteriorated bushing.

How many bushings are required for a complete service?

While this part is sold individually, a complete service of a Bravo drive's two trim cylinders typically requires four bushings in total (two per cylinder: one upper and one lower). Please verify the quantity needed for your specific repair.

Is this a direct replacement for OEM part 23-807073?

Yes, this is a direct aftermarket replacement for MerCruiser part number 23-807073 and also cross-references to Sierra 18-4288 and A.A Power 23-44165.

Is any special tool needed for installation?

Installation is a "press-fit." While a dedicated bushing press is ideal for safe and even installation, a proper-sized socket and a vice or clamp can often be used to carefully press the new bushing into place.
