The Multiquip 22996 is a genuine OEM Engine Subaru 9.0 HP EX27 designed for Whiteman walk-behind power trowel models B46S90, B46, BH90C, BH11C, and BS90C. As a direct OEM replacement sourced through Multiquip's authorized parts program, the 22996 ensures exact engine fitment with no guesswork on compatibility. Keeping your trowel powered by the correct Subaru EX27 engine maintains the performance characteristics the machine was engineered around, from consistent blade speed to dependable startup in demanding field conditions.
Key Features
- Certified OEM Power Source — Genuine Multiquip-sourced Subaru EX27 engine built to the same output specification as the original, delivering the correct RPM range and torque curve your trowel depends on.
- Direct Engine Replacement — Engineered to mount directly to B46S90, B46, BH90C, BH11C, and BS90C trowel frames using the original mounting footprint and shaft dimensions.
- Broad Whiteman Trowel Compatibility — Confirmed fitment across five Whiteman walk-behind power trowel models, making this the go-to engine replacement for fleets running mixed configurations of the B and BH series.
- Consistent Blade Drive Performance — A correctly matched 9.0 HP Subaru EX27 engine sustains the blade speed needed for proper concrete finishing; an underpowered or mismatched engine leads to uneven troweling and surface defects.
- Fuel System and Ignition Integrity — Replacing a failed or worn engine with the OEM-specified unit restores correct fuel delivery and ignition timing, reducing the risk of hard starts and rough running on the finishing floor.
The Subaru EX27 is an air-cooled, four-stroke gasoline engine commonly used to power walk-behind concrete finishing trowels. It drives the gearbox that spins the trowel blades, so the engine's output directly determines blade speed, finishing consistency, and overall machine responsiveness. When an engine begins to lose compression, develops starting problems, or fails entirely, the trowel becomes unusable — a complete engine replacement with the OEM-specified unit is the most reliable path to restoring full operation.
