Troubleshooting & FAQ
How do I know if this shift plate fits my MerCruiser engine?
This kit is designed for MerCruiser sterndrive and inboard engines equipped with EFI (Electronic Fuel Injection). The most reliable method of confirming fitment is to match the part number 864364A1 to your old part or your engine's service manual.
What are common signs of a failing shift plate?
Symptoms of a worn or damaged shift plate include difficulty shifting into or out of gear, grinding noises during shifting, the drive popping out of gear, or a loose or sloppy feel in the shift handle.
Can I install this shift plate kit myself?
While installation is possible for those with mechanical experience, professional installation is recommended. Proper alignment and adjustment of the shift cables are critical for correct and safe operation.
