Key Features
- Genuine OEM Honda Power Source — Honda GX340 engine delivers the consistent 11hp output your QP-40TH trash pump depends on for sustained high-volume pumping performance.
- Exact OEM Replacement — Sourced directly through Multiquip's authorized parts program, this engine matches the original mounting configuration and output specs of the QP-40TH.
- Confirmed QP-40TH Fitment — Engineered specifically for the QP-40TH trash pump; no guesswork on compatibility when ordering by model.
- Sustained Pumping Capacity — A properly functioning GX340 engine maintains the flow rate and prime recovery speed the QP-40TH is rated for; a worn or seized engine brings the entire pump operation to a halt.
- Fuel System Integrity — As a primary power source replacement, installing the correct OEM engine preserves proper fuel delivery, ignition timing, and throttle response critical to safe pump operation.
The Honda GX340 is a single-cylinder, air-cooled four-stroke gasoline engine that serves as the primary power source for the QP-40TH trash pump. It drives the pump impeller at the speed needed to move high volumes of water and entrained solids on demanding jobsites. When the engine fails — whether through wear, seizure, or irreparable damage — the entire pump is rendered inoperable, making a correct engine replacement essential to restoring full machine function. Installing the right OEM engine ensures proper shaft alignment, throttle calibration, and mounting integrity so the pump runs as designed.
