Kawasaki FS541V-S28 15HP Vertical Small Gas Engine

1-1/8" (28.575mm) x 4-5/16" (108.8mm) • 603cc • Recoil Start

The Kawasaki FS541V-S28 is a commercial-grade 15 HP small engine engineered for equipment that demands long-lasting power, consistent torque, and true reliability in the field. Built around a 603cc 4-stroke OHV twin-cylinder platform, this engine is ideal for zero-turn mowers, walk-behind commercial mowers, residential equipment, and other small machinery that must work in dusty, hot, or high-demand environments.

At the core of this model is a 1-1/8" x 4-5/16" vertical keyed shaft, offering broad compatibility with a range of machinery setups. Paired with recoil pull start, clutch coil, and dedicated choke & throttle controls, the FS541V-S28 supports hands-on use in outdoor job sites where reliability matters more than anything.

A Compact Powerhouse With Commercial-Ready Engineering

• 603cc displacement delivers powerful torque for cutting thick grass, slopes, or heavy workloads.
• 4-stroke OHV V-twin configuration provides smooth output and improved fuel economy.
• Forced-air cooling system protects against overheating during prolonged use.
• Pressurized oil system with filter ensures proper lubrication and longevity under load.
• High-efficiency oil cooler maintains optimal performance in extreme weather or dusty environments.

Every detail of the FS541V-S28 reflects Kawasaki’s commitment to strength, reliability, and long-term durability.

Outdoor power equipment engines face constant abuse: grass debris, dust, inconsistent terrain, vibration, and long duty cycles. Kawasaki designed the FS Series to thrive in those conditions.

The FS541V-S28 includes:

• Rotating grass screen to reduce debris buildup around the cooling system.
• Dual-sealing cartridge air filter to protect the intake system and extend service intervals.
• Clutch coil setup for PTO applications and attachments.
• Keyed straight vertical shaft for easy replacement and stable mechanical connection.

These design elements help reduce downtime, extend equipment life, and ensure predictable performance even in harsh environments.
