Multiquip 22618 Honda GX630 20HP Engine - OEM Replacement Part

This Honda GX630 gasoline engine delivers 15.5 kW (20.8 HP at 3600 rpm) to power Multiquip ride-on power trowels through demanding concrete finishing operations.

Designed specifically for high-output ride-on trowels, this engine supports equipment operating at 616 lbs with dual rotor configurations running at 138 RPM on dry concrete. The engine's 2.3-gallon fuel capacity provides extended runtime for large-scale finishing jobs. Engine oil capacity is 2 quarts (1.9 liters) with a new filter, and regular maintenance should follow daily pre-operation checklists including oil level verification before each use.
