Quicksilver sea water pump body kit 807151A14 for MerCruiser — phenolic resin body, elastomer impeller & wear plate

This replacement kit from Quicksilver includes the pump body, impeller, wear plate, O-ring, and all necessary attaching hardware to restore cooling circulation on compatible MerCruiser engines with one-piece, engine-mounted sea water pump systems. Built using a two-step phenolic resin for structural strength and paired with elastomer impellers designed for broad temperature flexibility, the kit targets durability and dependable performance across the boating season. Follow your engine service manual for installation procedures and replacement intervals.

Which components are included in the 807151A14 kit?

The kit arrives ready to install with every core component needed to replace an engine-mounted, one-piece sea water pump body. Parts are matched to MerCruiser specifications so you don’t have to source separate pieces.

• Replacement sea water pump body specifically shaped for one-piece, engine-mounted designs
• Quicksilver impeller molded from flexible elastomer for consistent sealing
• Wear plate and O-ring to restore proper clearances and prevent leaks
• Attaching hardware to secure the pump body to the engine mount

How does the material choice affect durability and performance?

The pump body is made from a two-step phenolic resin compound selected for strength and dimensional stability in marine conditions. The result is a body that resists distortion and maintains fitment under load, while the engineered impeller elastomer remains flexible across temperature swings for improved priming and longevity.

• Phenolic resin offers high compressive strength and wear resistance
• Two-step manufacturing ensures consistent thickness and rigid mounting surfaces
• Impeller elastomer tailored for seasonal temperature ranges to reduce cracking
• Wear plate minimizes rotor-to-housing friction for extended service life

What engines and installations is this kit compatible with?

This Quicksilver kit is intended for MerCruiser engines that use a one-piece, engine-mounted sea water pump design. Confirm fitment against your engine service manual or parts diagram to ensure correct application before purchase.

• Designed for MerCruiser engines with one-piece, engine-mounted pumps
• OEM replacement part engineered to match Mercury Marine specifications
• Suitable for routine replacement when your service manual indicates pump maintenance
• Not intended for remote-mounted or multi-piece pump assemblies

How should I approach installation and maintenance?

Install this kit following the procedures in your engine service manual; proper torque, alignment and priming are important to avoid cavitation and leaks. Regular inspection of the impeller and housing during the season helps you catch wear early and preserve cooling system reliability.

• Refer to the engine service manual for step-by-step removal and installation
• Inspect the impeller for cuts, cracks or stiffness before reuse
• Replace the O-ring and wear plate whenever the pump body is serviced
• Check for proper torque and alignment to prevent premature wear

Who is this for: Boat owners, mechanics and fleet managers who operate MerCruiser-equipped vessels with engine-mounted one-piece sea water pumps and need an OEM-grade replacement. If you value fit-to-original specifications, rugged materials, and components developed by the maker of Mercury Marine original equipment, this Quicksilver 807151A14 kit provides a straightforward path to restoring dependable raw-water cooling performance.
