Simple...We have been in business since 2005, and our engines are fully rebuildable with all parts available. We have a USA (Michigan) based team that are professionals in the industry, and are ready to answer your questions right away.The Rehlko Command Pro EFI ECH749-3126 is a premium 26.5 HP 747cc V-Twin commercial engine built for demanding mower, turf, and industrial applications that require dependable power, efficient fuel delivery, and long-term durability. Formerly sold under the Kohler name, Rehlko continues that same trusted engine platform with advanced engineering for commercial users who need strong performance and reduced downtime.
Designed with a flush crankshaft and configured for E16 Walker applications, this engine is a strong replacement option for compatible commercial equipment where fit, performance, and reliability matter. With Electronic Fuel Injection (EFI), the ECH749-3126 provides more precise fuel management than traditional carbureted engines, helping improve starting, throttle response, fuel efficiency, and overall consistency across a range of working conditions.
At the heart of this engine is a 747cc 4-stroke OHV V-Twin design built to handle long operating hours and heavy-duty use. The EFI system automatically adjusts fuel delivery based on engine demand, which helps reduce common carburetor-related issues and provides more dependable operation in changing temperatures and workloads. For commercial cutters, grounds crews, and equipment operators, that means less interruption and more confidence in the field.
The heavy-duty electric start system provides reliable key-start ignition, while the engine’s pressure lubrication system, remote air cleaner, and forced air cooling help support long service life in tough environments. Integrated durability features like the oil cooler, mechanical governor, and robust internal components make this engine a solid choice for users who expect their equipment to perform day after day.
Because this model uses a flush crankshaft, it is especially important to verify equipment compatibility before purchase. If you are replacing an older engine on a Walker mower or other commercial machine, Carroll Stream Motor Company can help confirm fitment before you order. That extra support can help prevent downtime, returns, and installation issues.
Carroll Stream Motor Company has been serving engine customers since 2005, providing high-quality small engines, replacement engines, and expert support from a knowledgeable Michigan-based team. Every engine sold is backed by real product knowledge, access to parts, and a commitment to helping customers choose the correct engine for their application.

Frequently Asked Questions
What is the Rehlko ECH749-3126?
The Rehlko Command Pro EFI ECH749-3126 is a 26.5 HP 747cc V-Twin small engine with Electronic Fuel Injection (EFI) and a flush crankshaft, commonly used in commercial mower and industrial equipment applications, including E16 Walker setups.
Is Rehlko the same as Kohler?
Yes. Rehlko is the new name for Kohler Engines. The Rehlko brand continues the same commercial engine platform and support network that many buyers already know from Kohler.
What are the benefits of EFI on this engine?
EFI helps provide more precise fuel delivery, easier starting, improved throttle response, and more consistent operation compared to many carbureted engines. It can also help reduce maintenance issues commonly associated with carburetors.
What does flush crankshaft mean?
A flush crankshaft means the crankshaft does not extend outward like a traditional keyed shaft. This style is used for specific OEM equipment applications, so it is important to verify compatibility before ordering.
Does this engine have a warranty?
Yes. This engine includes a 3-year consumer warranty and a 3-year commercial warranty.
Can this engine replace an older Kohler or other commercial engine?
In many cases, yes, but replacement compatibility depends on the equipment, mounting pattern, crankshaft setup, and application. Carroll Stream can help verify fitment before you buy.
