What the difference means
- Torque is what you feel in a tiller, pump or go-kart pulling from low speed: 7.6 vs 9.1 lb-ft at 2,500 rpm.
- Mounting: both share Honda’s same engine family, so overall size is close (12.2 × 14.3 × 13.6 in (312 × 362 × 346 mm) vs 12.6 × 14.8 × 13.6 in (321 × 376 × 346 mm)). Still check the bolt pattern and shaft for your exact type before swapping.
- Shaft: both come in several PTO shaft types (straight, tapered, threaded, reduction). The type letter after the model name on the engine label tells you which.
- Fuel use rises with load and displacement; the bigger engine only costs more fuel when you actually use its extra power.
Rule of thumb: pick the smaller engine when the equipment maker lists it as an option and you run it at part load; pick the larger one for pumps, splitters and karts that run near full load for long periods.
