Key Features

• Genuine OEM Power Source — An authentic Briggs and Stratton 8HP engine sourced through Multiquip's authorized parts supply, matched to the original engine specification for these mixer models.
• Broad Mixer Compatibility — Fits EM-700P, EM-900S, EM-700S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P plaster and mortar mixers.
• Drop-In Engine Replacement — Engineered to the same mounting and output configuration as the original, allowing direct installation without custom adaptation.
• Sustained Mixing Performance — A correctly rated 8HP engine delivers the torque needed to turn heavy mortar or plaster loads continuously without bogging or stalling.
• Fuel System and Ignition Integrity — A fresh OEM engine eliminates fuel delivery, compression, and ignition issues that accumulate in high-hour or damaged units, restoring clean, dependable starts.

The engine is the primary power unit on a mortar or plaster mixer, driving the gear reduction system that rotates the drum and keeps material moving at the correct speed and consistency. An 8HP Briggs and Stratton engine provides the torque necessary to handle dense mixes without overloading the drivetrain. When an engine loses compression, develops fuel system faults, or fails entirely, drum rotation becomes erratic or stops altogether — halting production until the unit is replaced. Installing part number this part restores the correct power output and gets the mixer back to full working capacity.
