Troubleshooting & FAQ

Q: How do I confirm this bracket fits my sterndrive?
A: This bracket is designed for MerCruiser Pre Alpha, Alpha I, Alpha II, and Bravo sterndrives from 1983 and later. Please check the ""Compatible Engine Models"" table and cross-reference your OEM part number (862548A1 or 42419A1) to ensure a perfect match.

Q: What is the advantage of this stainless steel bracket over the painted steel OEM version?
A: The original OEM brackets were typically made of painted steel, which can corrode and rust over time, especially in saltwater environments. Our aftermarket bracket is made from stainless steel, offering superior corrosion resistance and durability for a longer service life.

Q: What are common signs that my original trim pump bracket needs replacement?
A: Telltale signs include visible rust or corrosion, stress cracks in the metal, or the bracket physically breaking, causing the pump assembly to become loose. A failing bracket can lead to pump misalignment and further damage.

Q: Does this bracket include mounting hardware?
A: The package contains the bracket only. You will typically reuse your existing mounting bolts and hardware. Please verify the condition of your hardware before installation and replace if necessary.
