Rated Output Question

[bartles]

I have a B&S model 125K02-0477-E1, s/n 04122858. I thinking about replacing it with a Honda engine from a power washer.
What is the rated RPM of the B&S engine? I can locate that data within the B&S website.

Usually 3600 RPM is considered the normal max RPM. But you must consider the max rated rpm of the pump being driven.

Gee, thanks for the crank info! The Honda pressure pump engine is rated at 3400 RPM...should be a good match for power.

he gave you the crank specs because the replacement engine must fit the pressure washer pump. They are not all the same.
