## Description

## Who it’s for

A 3/4-inch horizontal-shaft pump is the defining fit for this YAMATIC replacement. It’s designed for compatible gas pressure washers with 180–208cc or 5.5–7 HP engines, giving owners a way to replace the pump rather than the entire machine. If your priority is restoring an existing washer, this axial cam design serves a different need than buying a complete pressure washer. It can be used for household washing tasks such as cleaning walls, sidewalks, and vehicles.

Fit depends on more than the washer’s brand or pressure rating: the engine shaft, mounting pattern, inlet and outlet, and frame clearance must match. The pump is intended for 3/4-inch horizontal shafts and is not designed for vertical engines, 7/8-inch or 1-inch shafts, or idle-down systems. Listed compatible examples include Honda GC190, Kärcher G3050OH and G3200HH, and Generac 0064130, confirm the specific setup against your existing pump and washer before installation.

## Strengths

The pump is rated for up to 3400 PSI and 2.5 GPM, with a maximum speed of 3400 RPM. Its aluminum pump head and brass components make up a compact axial cam replacement for compatible gas-powered equipment. A thermal relief valve releases hot water and draws in cooler water while the pump is in bypass, helping protect it from heat buildup. The adjustable unloader lets pressure be set to suit the engine.

The pump arrives pre-filled with oil, and its easy-start structure is intended to make pull-back starting easier. Standard SAE bolt patterns and included mounting hardware support the replacement process. Customer feedback often highlights the straightforward changeout and fit, reports on pressure performance and long-term durability are mixed, so choosing the correct configuration remains central to a successful replacement.

## Key points

## Practical questions

**Will it fit any pressure washer from a listed brand?** No single brand name determines fit. The washer needs a matching 3/4-inch horizontal shaft, mounting pattern, inlet and outlet arrangement, and frame clearance. Check the specific model and setup, including the listed examples, before fitting the pump.

**Can it be used with hot water?** It is intended for cold-water pressure washing. The thermal relief valve helps manage heat buildup during bypass operation, it does not make the pump suitable for a hot-water system.

**What comes with the pump?** The package includes the pump, a siphon tube with filter, four mounting bolts, a shaft key, and a product manual. The pump is pre-filled with oil.

## Final verdict

For owners of a compatible gas-powered washer, the YAMATIC 10P2923HA offers a focused replacement path with a 3/4-inch horizontal shaft, axial cam construction, and a 3400 PSI maximum rating. Match the connections and mounting setup to your machine, and it’s suited to putting an existing pressure washer back to work on common home cleaning jobs.
