Engines
High Power. High Performance. Genuine.
Genuine Maruyama Power. Maruyama designs, engineers and builds engines in three distinct classes. Each is the product of years of hard won, field-proven experience in two-stroke technology. Each is high performance and highly serviceable, full of quick, high torque power and long-term reliability. And each is a model of the extraordinary quality that is the foundation of our products and our reputation.
- The Iron 5 commercial warranty. The only 5 year commercial-use warranty in the industry.
CER Class Engine
Incredibly fuel efficient!
The MARUYAMA CER series 2-Stroke engines are the latest in our line of ultra-clean models using our revolutionary HERE (High Efficiency Recirculator Engine) technology. With this technology, we can meet or exceed today’s ultra-low Tier3/Phase3 CARB and EPA engine regulations. With 30cc and 42cc models, this is done without the need for a catalytic muffler. For all CER models, this is done using fewer components and a proven, less-costly single-venturi rotary Walbro carburetor. The most significant visible change is internal; a pair of recirculator grooves across the exhaust face of the piston. These engines produce excellent power and torque characteristics with fuel economy as much as 50% lower than prior models.
- Made from the highest quality materials and components using state-of-the-art CNC and robotics.
- Incredibly fuel efficient; Best in class fuel economy. As much as 50% better than prior models.
- Crankcase volume configured to provide max. efficiency of recirculator (HERE) design.
- Larger flywheel and cylinder fin area for max. cooling.
- Walbro 1-pc. PCI ignition on some models; Internally advances timing for optimum performance and lowest emission output.
- Hard chrome-plated cylinder for an even LONGER engine life.
- Heavy-duty, washable foam air filter.
- Ultra-smooth polished chrome surface for lowest possible emissions.
- Inside the engine, the piston recirculator grooves are the key to the patented HERE low-emission system.
- All ball and needle-bearing construction inside engine.
- Stainless steel mufflers designed for best performance and low noise.
- Forged, chrome-moly 3-pc. crankshaft with forged conrod.

VENOM Engine
Incredibly fuel efficient; About 50% savings over non-compliant engines!
The new MARUYAMA VENOM Series 2-Stroke engines are much more technologically advanced than their predecessors. We have implemented our state-of-the-art HERE PHASE2 (3rd Generation Recirculator design – High Efficiency Recirculator Engine) technology in the creation of these ultra-clean modeled engines.
The VENOM B42 and B30 engines meet today’s ultra-low Tier3/Phase3 CARB and EPA engine regulations. With these 41.5cc and 30.2cc models, this is done without the need for a catalytic muffler. Our VENOM brush cutters cut with a vengeance.
