Rhino CS177 9HP Gas Engine – Recoil Start, 1" Horizontal Shaft (270cc)
HIGHEST QUALITY GUARANTEED! Same day Shipping!
The Rhino CS177 9HP Recoil Start Gas Engine from Carroll Stream Motor Company is a powerful, reliable, and versatile small engine designed for a wide range of residential, commercial, and industrial applications. Built with a 270cc 4-stroke OHV single-cylinder design, this engine offers dependable performance for equipment that needs strong and steady RPM without a gear reduction system.
This general-purpose 9HP model is ideal for equipment such as pressure washers, air compressors, go-karts, mini bikes, tillers, pumps, trenchers, generators, and compact farm implements. If you need a fast, responsive engine with direct output speed rather than torque multiplication, the CS177 is the perfect fit.
Built for Reliable Everyday Power
The CS177 delivers 9 horsepower at 3600 RPM and 11.4 ft-lbs of torque, offering an excellent balance of speed and pulling strength. This makes it especially effective for rotating equipment, wheeled applications, and machinery where quick response and consistent throttle output are needed.
Easy Recoil Start – Simple & Dependable
The recoil pull-start system ensures fast and reliable ignition in any weather condition. With no batteries or wiring required, this engine is field-ready and easy to maintain — perfect for jobsite, farm, backyard, or workshop use.
Built with a cast iron cylinder sleeve for long-term durability, the Rhino CS177 is engineered to withstand heavy workloads. The splash lubrication system ensures consistent internal oiling, reducing wear on moving parts. A low-oil shutdown feature provides an additional layer of protection during extended use.
Compact, Lightweight & Easy to Install
With a 1-inch keyed horizontal shaft (1/4" keyway) and 55 lb lightweight frame, the CS177 integrates easily into most machinery platforms. Its 15 x 17 x 17 inch compact size fits tight equipment bays while still offering professional-grade performance. Equipped with a 1.58-gallon fuel tank, this engine supports extended operation with fewer refuel stops, making it suitable for continuous-use equipment. The overhead-valve design also maximizes fuel efficiency and ensures clean, consistent combustion.
