Solas MC-CD-22/39 Concord 4-Blade Stainless Steel Impeller for Mercury Sport Jet 184mm Pump

The Solas MC-CD-22/39 Concord Impeller is a high-performance, 4-blade stainless steel progressive pitch impeller engineered for Mercury M2 Sport Jet pump systems with a 184mm pump diameter. Built as part of Solas' Power Torque Series, this impeller is a direct-fit replacement that delivers a meaningful upgrade in thrust, acceleration, and overall pump efficiency over the stock unit.

The Concord's large-area blade geometry and radial leading edge are specifically optimized to complement four-stroke engine characteristics, producing strong low-end pull and sustained top-end performance across a wide range of operating conditions — from towing water skiers to wide-open cruising.

Key Features:

• 4-Blade Progressive Pitch Design — 22/39 pitch configuration tuned for mostly stock engine setups, improving low-end acceleration and adding 1–2 MPH at top speed
• High-Strength Stainless Steel Construction — Corrosion-resistant material built for long-term durability in marine environments
• Large Geometric Blade Area — Maximizes water displacement and thrust output through the pump
• Radial Leading Edge — Optimizes water flow entry into the pump housing for improved efficiency across the RPM range
• Power Torque Series — Engineered for rough-water hook-up and bottom-end planing performance
• OEM Cross-Reference — Replaces Mercury OEM impellers 47-877326T and 47-877325T
• Direct Replacement — No modifications required for installation; fits the Mercury M2 pump only

The MC-CD-22/39 is part of Solas' Concord series, recognized as a premium performance upgrade for Sea-Doo jet boats equipped with the Mercury M2 jet drive system. The stainless steel construction and precision blade geometry ensure consistent, reliable performance season after season.
