i built this and the motor went after a month, the nice thing about it is the cat pump which runs at 3000psi & 38lts a minute, the pump is geared to turn at only 800rpm they cost £2000!!
a new engine and you will have an amazing pressure washer, its not portable and i meant it to be mounted permanently in the van.
its been sat on my patio for 3 months while a new engine came up on Ebay but now its just in the way
