Multiquip 520766 Honda 13HP Electric Start Engine - OEM Replacement Part

This Honda 13HP electric start engine delivers reliable power for hydraulic plaster and mortar mixers in demanding concrete application environments. Designed as a direct replacement for the original Honda GX390RT2-QNB2 engine, this EPA-compliant power plant features a 389cc air-cooled 4-stroke design with a horizontal shaft configuration optimized for hydraulic pump operation.

The engine produces 11.7 hp at 3,600 rpm maximum output with 9.0 hp continuous operation, providing consistent hydraulic pressure for drum rotation and dump action in professional mixing applications. Key specifications include an 88mm × 64mm bore and stroke, electric start ignition system, centrifugal fly-weight speed control, and a 5.0 gallon fuel tank capacity for extended runtime. The crankcase holds 1.16 quarts of lube oil and requires regular maintenance inspection of hardware connections to prevent early component failure.

This replacement engine is compatible with the following Multiquip models:

• PRO12/PRO12E51
• PRO12C/PRO12E51C
• WBH-16
