Troubleshooting & FAQ
Why is this bracket stainless steel when the original was not?
The original OEM bracket was made of regular steel, which frequently rusts and deteriorates in the marine environment, leading to pump failure. This aftermarket bracket is made from corrosion-resistant stainless steel to provide a much longer service life and prevent rust-related issues.
How can I confirm this fits my specific boat?
This bracket fits a wide range of MerCruiser sterndrives from 1983 to present, including MR, Alpha I & II, and Bravo I, II, & III models. The key is to cross-reference your existing part number with the ones listed in our Part Number Matrix (42419A1, 862548A1, etc.). Also, verify your drive does not use the quick-release wiring harness.
What are the signs of a failing trim pump bracket?
Common signs include visible rust and corrosion on the bracket, the trim pump becoming loose or shifting, or a complete failure where the bracket breaks and the pump detaches. This can cause the trim/tilt system to stop working entirely.
Is this a complete kit or do I need other parts?
This kit includes the stainless steel bracket and the necessary mounting bolts and washers. You will reuse your existing trim pump, motor, and reservoir. No other parts are required for the bracket installation itself.
What tools are required for installation?
You will typically need a basic socket/wrench set to unbolt the old bracket and install the new one, along with tools to disconnect hydraulic lines (flare nut wrenches are recommended to prevent stripping fittings). Safety glasses are also highly recommended.
