Troubleshooting & FAQ
How do I know if this bracket fits my MerCruiser sterndrive?
This bracket is designed for MerCruiser Alpha I, Alpha II, Bravo, and Pre-Alpha sterndrives from 1983 and newer. It directly replaces OEM part numbers 862548A1 and 42419A1. We strongly recommend comparing your old part to our product images and specifications to confirm a perfect match.
What is the difference between this bracket and the original OEM part?
Our aftermarket bracket is constructed from stainless steel for superior corrosion resistance and longevity, whereas the original OEM parts are typically made from painted steel. It is engineered to meet or exceed OEM specifications for fit, form, and function.
What are the signs my trim pump bracket needs replacing?
Common signs of a failing bracket include heavy rust or corrosion, visible cracks in the metal, or the trim pump assembly becoming loose in its mounting. A damaged bracket is a safety concern and can cause failure of the trim system.
