Solas YJCD1217 Concord Impeller YJ-CD 12/17 for Yamaha TR-1 144mm PWC

The Solas YJ-CD-12/17 Concord Impeller is a high-performance upgrade designed for Yamaha personal watercraft equipped with the 1,050cc TR-1 engine and a 144mm diameter wear ring. Built for modified craft, this impeller is a featured component in Stage 1 performance kits for the Yamaha SuperJet and EX series, delivering a significant step up from stock pump performance.

Solas engineers the Concord line around its power-torque blade philosophy — combining a large blade area with a precision geometric blade design and a radial leading edge to generate remarkable thrust and extraordinary pump efficiency. The progressive pitch design, moving from a smaller pitch at the leading edge to a larger pitch at the trailing edge, allows the blades to aggressively grab water and accelerate it through the pump for improved response across the RPM range.

Key Features:

• Progressive pitch: 12° leading edge / 17° trailing edge for balanced acceleration and top speed
• 144mm pump diameter compatibility with Yamaha TR-1 engine applications
• Large overlapping blade area maximizes water draw-through and pump vacuum
• Superior hub design improves mechanical efficiency and durability
• Ultra-high-strength stainless steel construction — corrosion resistant and cast in a one-piece mold for precise blade geometry
• Includes nose seal
• Impeller installation tool sold separately

The Solas Concord series is purpose-built to complement modern four-stroke PWC engine characteristics, enhancing both low-end thrust and high-end performance. Whether building a Stage 1 setup or fine-tuning an already modified craft, the YJ-CD-12/17 is an excellent choice for riders seeking measurable gains over the factory impeller.
