Troubleshooting & FAQ
How do I know which shims to use from the set?
The specific shims required depend on your application and the measurements taken during installation. Always refer to your Mercruiser service manual for the correct shimming procedure and clearance specifications.
What are the signs that my sterndrive needs new shims?
Symptoms can include excessive vibration, unusual noises (grinding or whining) from the drive unit, or difficulty shifting gears. Incorrect alignment, which shims correct, can lead to premature wear on gears and bearings.
Can I reuse old shims?
It is not recommended. Old shims may be worn, compressed, or damaged, which can prevent you from achieving the correct tolerances. Always use new shims for critical alignments.
Is this shim set for the upper or lower unit?
This versatile shim set is used in various locations on Mercruiser Bravo drives and transom assemblies for setting bearing preload and gear backlash. Check your manual to confirm the specific application for your repair.
