Vanguard 300

The Vanguard 300 horizontal shaft engine delivers 7.5 gross kW (10.0 HP) of rugged single-cylinder performance, tailored for high-demand applications including high-pressure pumps, generators, and industrial-grade uncrewed systems. Designed from customer feedback, it integrates advanced start-up capabilities, longer maintenance intervals, and a drop-fit design for effortless replacement of standard engine formats—all backed by a 3+1 year commercial-use warranty.

  • Lower noise. Less vibration. Increased user comfort: Engine construction reduces both sound and vibration levels to boost productivity and comfort in extended-use environments.
  • Low TCO, reduced downtime: Extended 600-hour air filter and doubled oil change intervals drive longer uptime and fewer service disruptions.
  • Ideal for simple replacement: Directly replaces the most common engine models—no modifications needed.
Features & Benefits
  • Simplified 3-Step Starting
    Redesigned recoil system shortens pull distance and lowers force needed for ignition. Validated to start reliably in conditions down to -29°C.
  • Eliminate Fuel/Oil Dilution
    The patented TransportGuardâ„¢ 3-in-1 switch halts both ignition and fuel flow simultaneously, eliminating oil contamination from fuel seepage during transport or storage.
  • Optimized Fuel Management
    Enhanced fuel system improves stability when using older or degraded fuel, keeping the engine ready for action at all times.
  • Advanced Engine Protection
    Internal oil level sensor prevents damage by triggering shutdown during low-lubricant conditions—extending engine life in rugged field use.
  • Outperforms in All Terrains
    Optional 45° High Inclination Package ensures full power and oil distribution on steep grades, suitable for uncrewed platforms operating in variable topography.
  • More Efficient Power Management
    Governed idle maintains consistent output during low-load conditions, supporting precise control and efficient fuel consumption.
  • Fewer Air Filter Changes
    Cyclonic filtration design allows 600-hour air filter intervals—twice the service life of industry-standard units, increasing uptime and lowering replacement costs.
  • Longer Oil Maintenance Intervals
    Extended oil change cycles reduce downtime and cut oil waste by up to 50%, helping lower both maintenance costs and environmental impact.
  • Zero Overhang Muffler (Optional)
    Flush-mount muffler creates a flat surface for easier integration and replacement, improving compatibility with compact installations.
  • Reduced Noise and Vibration
    Engine balancing and structural improvements deliver significantly quieter operation and smoother performance under load.
