Troubleshooting & FAQ

Which MerCruiser drives will this bracket fit?

This bracket is designed for a wide range of MerCruiser sterndrives from 1983 and newer, including Pre-Alpha, Alpha I, Alpha II, and Bravo series, that require a floor-mounted trim pump.

Is this bracket stainless steel or regular steel?

This aftermarket bracket is made from stainless steel, offering enhanced corrosion resistance compared to the original OEM parts, which were typically painted steel.

How can I tell if my trim pump bracket needs replacement?

Signs of a failing bracket include visible rust or corrosion, cracks in the metal, or the pump assembly feeling loose. A damaged bracket can cause pump misalignment and hydraulic or electrical failures.

Does this part include mounting bolts or screws?

The package contains the bracket only. You will need to reuse your existing mounting hardware or purchase new marine-grade bolts suitable for your specific application.

Will this work for trim pumps older than 1983?

This bracket is specified for applications from 1983 and later. Fitment on pre-1983 models is not guaranteed and would require verifying dimensions and mounting patterns.
