Product Details
This stainless steel trim pump bracket is designed for MerCruiser floor-mount applications. It provides a corrosion-resistant replacement for the original metal bracket and supports secure installation of the existing trim pump assembly.

Troubleshooting & FAQ
Why use a stainless steel bracket?
Stainless steel offers improved resistance to corrosion in a marine environment compared with a conventional metal bracket. It is intended to help reduce rust-related deterioration of the mounting component.
How can I confirm this bracket fits my boat?
Compare your original bracket's shape, mounting location and hardware arrangement, and cross-reference the original number with 42419A1 or 862548A1. The available catalog evidence identifies the application as a MerCruiser floor-mount bracket, but it does not confirm every model, year or sterndrive variation.
Does this listing include the trim pump?
No. This listing is for the stainless steel mounting bracket. The trim pump, motor, reservoir, hydraulic lines and electrical components are not included.
Are mounting bolts and washers included?
Included hardware is not confirmed by the available product information. Inspect the package contents and verify that the replacement hardware is suitable before installation.
What are the signs of a failing trim pump bracket?
Common signs include visible rust or corrosion, a loose or shifting trim pump, damaged mounting points, unusual movement during operation or a broken bracket. Inspect the entire assembly before replacing only the bracket.
What tools are required for installation?
A suitable socket and wrench set is typically required. Flare-nut wrenches are recommended when disconnecting hydraulic fittings to reduce the risk of rounding them. Follow appropriate marine safety procedures and use eye protection.
Is this an OEM part?
This is an aftermarket stainless steel replacement bracket, not an original MerCruiser component. The MerCruiser numbers shown are original-equipment reference numbers used for identification.
Shipping speed and cost
Shipping availability, delivery time and cost are shown at checkout and may vary by destination and service level.
Warranty and returns
Warranty and return eligibility are governed by the current store policy. Review the applicable policy before installation, and retain the packaging and order details if a return or warranty claim is needed.
Safety & Important Info
- Disconnect the battery before working on the trim pump or its electrical connections.
- Hydraulic systems may be pressurized. Use suitable procedures and eye protection when disconnecting lines.
- Verify the bracket shape, mounting holes and reference number against the original part before purchase.
- Do not assume that every MR, Alpha or Bravo sterndrive uses the same trim pump bracket.
- This is an aftermarket replacement, not an OEM component. Professional installation is recommended when hydraulic or electrical work is required.
