LIYYOO Water Pump Housing & Impeller Repair Kit for Mercruiser Bravo 46-807151A14 — Phenolic Housing, OEM-Profile Impeller

LIYYOO's 46-807151A14 Repair Kit is a complete sea-water pump housing and impeller set engineered to replace Mercruiser Bravo 46-807151A14 components and restore reliable cooling flow.

When a Bravo-series raw water pump starts to leak or lose flow, swapping worn parts quickly prevents engine overheating and expensive damage. This LIYYOO kit includes a phenolic-resin housing and a matching impeller sized to fit the Mercruiser Bravo applications listed, offering a straightforward way to refresh the raw-water circuit with durable components compatible with several aftermarket cross-references.

What parts are included and how do they match Mercruiser models?

The kit provides a molded phenolic housing and a precision impeller manufactured to fit the same mounting pattern and internal clearances as the Mercruiser 46-807151A14 unit. It’s intended as a drop-in replacement for Bravo raw water pumps when the original housing or impeller is worn or damaged.

• Phenolic resin pump housing sized for Bravo mounting points
• Elastomeric impeller molded to OEM profile for proper flow
• Compatibility with Mercruiser Bravo 46-807151A14 and cross-referenced aftermarket numbers

How durable is the housing and what materials are used?

The housing is produced from a two-step phenolic resin compound, chosen for its resistance to seawater erosion and dimensional stability under heat. That construction balances rigidity with reduced corrosion risk compared with metal housings exposed to saltwater.

• Two-stage phenolic resin for improved wear resistance
• Stable under typical engine bay temperatures and saltwater exposure
• Less prone to galvanic corrosion than some metal alternatives

Will installation require special tools or modifications?

Installation is typically straightforward for anyone familiar with Bravo pump swaps and basic marine engine maintenance. The kit is designed to align with existing bolt patterns so no machining is normally necessary, but standard hand tools and marine sealant practices are recommended.

• Drop-in fit for compatible Mercruiser Bravo pump locations
• Standard hand tools suffice for removal and reinstallation
• Inspect gaskets, seals, and impeller timing during service for best results

How does this kit help prevent common pump failures?

Replacing both the housing and impeller at the same time addresses wear points that reduce flow and promote leaks. A new phenolic housing reduces internal scoring and maintains correct impeller clearance, while a fresh elastomer impeller restores vane flexibility and sealing.

• Restores correct internal clearances to improve water flow
• Replaces hardened or torn impeller vanes that cause cavitation
• Prevents seawater intrusion and reduces leak-related damage

Who is this for: This LIYYOO repair kit is aimed at boat owners, marine mechanics, and service yards maintaining Mercruiser Bravo outdrives or anyone who needs a reliable, phenolic housing and impeller set compatible with Mercruiser 46-807151A14 and equivalent aftermarket parts. Choose this kit when you want a durable, ready-to-install replacement to restore raw-water pump performance without extensive modification.
