When This Part Needs Replacement
Replace the power steering pump if it leaks fluid, whines or growls during steering, causes heavy steering effort, produces foamy or contaminated fluid, or fails to provide consistent hydraulic assist.
Installation Notes
This pump is supplied without the pulley. Inspect the existing pulley, belt, brackets, hoses, fittings, and fluid condition before installation. Use the correct pulley removal and installation tools to avoid damaging the pump shaft, and refill/bleed the steering system according to Mercury service procedures.

Parts Desk Insight
The “without pulley” detail matters on this pump. The pulley, bracket alignment, and belt layout need to match the engine setup, so verifying the serial number and original pump configuration before ordering helps avoid install-day surprises.
