Installation Guide

1. Safety First: Disconnect the negative battery cable to prevent accidental starting.
2. Remove Lower Unit: Unbolt and carefully lower the gearcase assembly from the outboard engine.
3. Disassemble Old Pump: Remove the bolts securing the water pump housing. Lift off the housing and remove the old impeller, gaskets, and wear plate, noting their orientation.
4. Clean Mating Surfaces: Thoroughly scrape and clean the base of the pump and housing to ensure a perfect seal.
5. Install New Components: Place the new lower gasket and faceplate. Install the new driveshaft key and slide the new impeller onto the shaft, turning it clockwise to seat the vanes.
6. Secure New Housing: Install the new upper gasket and position the new housing assembly. Secure it by tightening the four new M6 x 20 screws to the manufacturer's specified torque.
7. Reinstall Lower Unit: Carefully guide the lower unit back into place, ensuring the driveshaft and water tube align properly. Re-fasten the mounting bolts.
8. Final Check: Reconnect the battery. With a proper water supply, start the engine and confirm a strong, steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

Q: How can I be sure this kit fits my specific Mercury Verado engine?

A: This kit is designed for Mercury Verado models from 200-400 HP. Please consult the 'Compatible Engine Models' table on this page to verify that your specific model and horsepower are listed. Cross-referencing the OEM part number (8M0065072) is the most reliable way to ensure a match.

Q: What are the common signs that my water pump is failing?

A: The most common indicators of a failing water pump are a weak or inconsistent water stream from the engine's tell-tale outlet, or a high-temperature alarm from your engine's monitoring system. A visual inspection of the impeller may also reveal cracked, brittle, or broken vanes.

Q: How often should the water pump kit be replaced?

A: As a general maintenance guideline, it is recommended to replace your water pump impeller and kit every two to three years or every 200-300 hours of operation, whichever occurs first. Regular inspection is advised, especially if operating in sandy or silty water.
