Quicksilver Impeller Repair Kit 8M0137219 for MerCruiser V6/V8 (2000+ brass pumps) — shorter heavy-duty impeller & wear plate

Quicksilver 8M0137219 is a dedicated replacement impeller repair kit engineered for MerCruiser V6 and V8 sterndrives (2000+ brass seawater pump models) to restore cooling circulation when the pump housing front is worn.

The 8M0137219 kit supplies a shorter heavy-duty impeller plus an over-molded inner (front) wear plate to address erosion or gouging at the seawater pump inlet. It’s designed for MerCruiser 305, 350, 496 and 502 CID engines fitted with brass seawater pumps manufactured 2000 and later. This kit is not compatible with Mercury/MerCruiser 4.5L or 6.2L engines. Use your engine’s parts list or service manual to confirm fitment before ordering.

How does this repair kit fix a worn seawater pump inlet?

The kit replaces the flexible impeller with a shorter, tougher design that maintains seal and flow in a damaged housing, while the over-molded front wear plate fills and protects the front face where debris has worn the inlet. Together they re-establish reliable suction and reduce cavitation caused by gaps or scoring in the pump housing.

• Includes heavy-duty, shorter impeller to compensate for housing wear
• Over-molded inner wear plate restores a smooth pump inlet surface
• Helps reduce turbulence and restore consistent cooling flow

Will this kit work on my MerCruiser engine?

Fitment is specific: the kit is made for MerCruiser V6 and V8 305, 350, 496 and 502 CID engines from 2000 onward that have a brass seawater pump. It does not fit Mercury/MerCruiser 4.5L or 6.2L models. Always verify with your owner’s manual or the engine parts diagram for the exact part number match.

• Compatible: MerCruiser V6/V8 305, 350, 496, 502 (2000+ with brass pump)
• Not compatible: Mercury/MerCruiser 4.5L and 6.2L engines
• Confirm via service manual, parts listing, or engine tag before purchase

What does the kit include and how does it improve durability?

The kit combines a reinforced impeller with an over-molded inner wear plate engineered to OEM standards to maximize life in compromised housings. Manufactured to meet Mercury Marine original equipment specifications, the components resist abrasion and extend the service interval when compared with a standard impeller alone.

• Shorter heavy-duty impeller reduces slippage in worn housings
• Over-molded front wear plate restores inlet geometry and protection
• Produced to Mercury Marine OEM-quality for reliable performance

How should I approach installation and maintenance?

Installation requires basic mechanical skill and adherence to your engine service manual. Inspect the pump housing and drive key, replace the gasket or seal if required, and check the impeller clearance and rotation direction during reassembly. Regular seasonal inspection of the impeller and strainer helps avoid overheating and premature damage.

• Follow the engine service manual for torque and alignment specs
• Inspect housing, keyway, and seals; replace any damaged parts
• Test-run engine and verify steady water discharge after install

Who is this for: Boaters and marine technicians who own MerCruiser V6 or V8 sterndrive engines with brass seawater pumps (2000 and newer) and who need a targeted repair when the front of the pump housing shows wear from debris or erosion. Choose this kit if you want an OEM-spec repair solution to restore cooling performance without replacing the entire pump assembly, and always confirm fitment with your engine documentation before purchase.
