Impeller Kit

Volvo Penta Impeller Kit M21951362 | Boat Supply Store

Maintaining consistent engine operating temperatures is critical for preventing costly damage and ensuring reliable performance in harsh marine environments. This genuine Volvo Penta impeller kit directly addresses cooling system inefficiencies caused by worn or damaged impellers, which can significantly restrict raw water flow. It is engineered with specific material densities and vane profiles to meet the exacting demands of D4 and D6 series marine diesel engines, providing superior volumetric flow rates essential for preventing overheat conditions in applications such as offshore trolling or extended cruising on the Gulf Coast. Replacing your impeller routinely, typically every 1000 hours or two years, directly preserves the integrity and efficiency of your marine propulsion system.

Specifications

Who This Is For

This kit is essential for owners of Volvo Penta D4 and D6 series marine diesel engines who prioritize reliable engine cooling. It is specifically designed for boaters performing routine maintenance to prevent premature engine wear and ensure consistent operation.

How It Compares

Common Concerns Answered

How often should this impeller be replaced?

Volvo Penta recommends replacing this impeller every 1000 operating hours or every two years, whichever comes first, to maintain optimal cooling system performance and prevent premature engine wear.

Can I use a generic impeller kit on my Volvo Penta engine?

While generic kits may fit physically, they often lack the precise material composition and vane geometry required for optimal flow and longevity in Volvo Penta D4/D6 series engines, potentially leading to overheating and reduced engine life.

What are the signs of a worn impeller?

Symptoms of a worn impeller include rising engine temperatures, reduced water flow from the exhaust, and unusual noises from the raw water pump. Prompt replacement is crucial to avoid engine damage.

Frequently Asked Questions

What specific Volvo Penta engine series is this impeller kit designed for?

This impeller kit is engineered for Volvo Penta D4 and D6 series marine diesel engines.

What is the primary function of this impeller kit?

The primary function is to efficiently pump raw water through the engine's cooling system to dissipate heat and maintain optimal operating temperatures.

Does this kit include all necessary components for replacement?

This kit typically includes the impeller itself. It is advisable to check if a new wear plate or seal is recommended for your specific engine model and service interval, which may be sold separately.

What is the material of the impeller vanes?

The impeller vanes are constructed from a proprietary rubber compound specifically chosen by Volvo Penta for its durability, flexibility, and resistance to wear in marine cooling environments.

What is the recommended replacement interval for this impeller?

The manufacturer's recommendation is replacement every 1000 operating hours or every two years, whichever occurs first.
