My original pump was failing. It was not developing pressure, and it sometimes locked up so that the starter cord was difficult to pull. I disassembled the pump, but nothing was obviously wrong. Rather than refurbish it with new check valves and fittings, I thought it would be easier to buy a new replacement pump entirely. This pump works very well. It's a straightforward replacement of the original. Three bolts are all that need attention.

I recently purchased the YAMATIC 7/8" Shaft Vertical Pressure Washer Pump as a replacement for my pressure washer, and I have been extremely impressed with its performance.First of all, the build quality of this pump is top-notch. It feels sturdy and durable, and I have no doubts that it will last for a long time. The 7/8" shaft size was a perfect fit for my pressure washer, and the installation process was quick and hassle-free.In terms of power, this pump delivers outstanding performance. It provides a maximum pressure of 3000 PSI, which is more than enough for tackling even the toughest cleaning tasks. Additionally, the 2.5 GPM flow rate ensures that water is delivered at a consistent and strong rate, providing efficient cleaning results.One of the standout features of this pump is its smooth and quiet operation. It runs quietly, which is a significant improvement over my previous pump. I appreciate being able to use my power washer without the loud rumbling of most pressure washers.I highly recommend this for your next replacement!

I used this to replace a pump unit that had failed. It works great, fit perfectly and develops plenty of pressure. It might be slightly more powerful than the OEM pump. I like it.

Installed easily and worked with no adjustments. Used for 10 min 2 times - only time will tell how long it will last.

Ordered this for a Simpson 2800PSI, 2.3 GPM, model MS60773 pressure washer. Water pump # was 510015. Pump arrived on date specified. My original pump had a round ring or plate with three mounting holes that also aligned with motor housing. The replacement had three legs that lined up with the mounting holes. Used the new bolts supplied but did not need spacers on my model. Have only used for about twenty minutes and worked fine. Seemed to have a little more spray force than before. As a side tip: I forgot to drain the water out of pump after not using during the winter months and had single digit temps for a few days and pump split where the sprayer hose connects. The shaft would not slide off. Sprayed lubricant to seep down shaft and let sit overnight. The next day it came off easily and was easy to attach replacement.

I bought this to replace the second pump I have installed on my Honda GCV160 engine pressure washer. This pump appears to be of lesser quality than the Annovi Reverberi pump that I installed after the OEM pump failed. With that said it is working. For now. Time will tell how long it last. The Annovi pump was very expensive and appears to be up much higher quality than this pump. Of course time will tell if this much cheaper pump survives for any reasonable length of time. I will say that the GCV160 is only rated for 5.5hp and this pump is recommended for a 6.5 hp or higher engine. So far my GCV160 seems to be keeping up but there are signs of it struggling. Time will tell if this combination holds together for any real length of time. So far I have only used it for about 20 minutes in total. With that said it does seem to be working well. I will update this review after I have a few hours of use. Unfortunately that probably won't be until next summer since we are heading into the winter here in NE and I don't use the pressure washer often in the winter.

I was just going to throw my 2600 psi Sam’s Club washer away once black sludge came out of the bottom and fouled my wooden deck I was trying to wash. Thought it was the engine, but found it was the pump itself that was leaking.Ordered the replacement and it fit right in the same bolt holes. Came with all new bolts, washers, 2 keyways, and spacers and a new suction hose with a filter for your soap reservoir. Didn’t need any of that and just used my old hardware. Installed it in about 15 minutes.Hooked it up and made sure water was going through it before starting the engine. It’s pumping like a champion and I washed for over two hours with no problems. Just remember, none of these pressure washers should run for over 30 seconds at a time without the trigger on the wand spraying. More than that and you risk overheating the pump and ruining it. I’m pretty sure that’s what happened to the first pump and made the seals fail and oil poured out.
