Quicksilver 8M6010334 impeller is developed specifically for Yamaha 4.2L 200–300 hp outboard motors with 25–30 inch shafts, where precise and stable cooling water flow is essential to protect the high-output engine components. The impeller is manufactured to OEM specifications, ensuring a precise fit and reliable operation throughout the engine’s entire rpm range, whether the motor is running under heavy load while planing or during extended operation at cruising speed. According to manufacturer data, this model is designed to provide continuous cooling for the large 4.2L engine blocks and is compatible with Yamaha’s OEM reference number 6CE‑44352‑00‑00, ensuring full interchangeability without the need for modification. The advanced elastomer construction provides high resistance to heat, cavitation, and mechanical wear—factors that large engines expose the impeller to through strong water flow. The impeller is a critical part of the engine’s cooling system, where even small reductions in water flow can lead to increased engine temperature and the risk of damage to the cylinder head, exhaust passages, and thermostat system. Quicksilver 8M6010334 therefore ensures optimal pressure stability in the water pump and gives the engine the operating conditions it was designed for, even under heavy loads such as tow lines, heavy cargo, or demanding offshore boating. The construction resists deformation from vibration, high rpm, and temperature fluctuations, making it especially suitable for large engines with high hydrodynamic loads. Benefits:

• OEM-compatible impeller developed specifically for Yamaha 4.2L 200–300 hp engines.
• Designed for engines with 25–30" shafts for optimal fit and reliability.
• High-performance elastomer that resists heat, cavitation, and vibration.
• Ensures stable cooling water flow and prevents overheating.
• Direct replacement for OEM units – no modification required.

Quicksilver 8M6010334 is therefore the safe and technically optimal solution for larger Yamaha engines, where maximum cooling efficiency and operating stability are essential for both performance and engine life.
