I have a 6hp, 3450rpm, 3/4 shaft motor. will this motor work with this pump rated at 3400rpm. Or can you recommend a single phase motor for this pump. Thanks.

Answer
Thanks for your inquiry. Yes, this pump will work on your engine. However, this is a bare pump without the inlet and outlet fittings. It also does not include the thermal relief valve. I would recommend purchasing the fully plumed pump model SLP4PPX30GSI-057. I have attached a link for you to view the same pump just fully plumed and ready to go.

can the 4PPX25GSI pump fit the northstar gsx 160 pressure washer

Answer
No, a Honda GX 160 does not have enough power to drive this pump. With your unit, I would recommend the General Pump model SLPTP2530-401. I have attached a link for you to view that item.
